Does the Loading Bar work in your games? I'm still trying to figure out how Unity splits scenes for loading, would be great to have a very gradual loading bar.
What about circular loading bar?? Or continue playing song on loading screen which was running on last scene On another words, Can you show me is it possible or not If any song is playing on first scene, before I jump on another scene I'll get loading screen with that song which was running on last scene without being stopped Hope you understand what I actually mean
Make sure your game object that is playing the music is not Destroyed on Load with the function DontDestroyOnLoad(gameObject); docs.unity3d.com/ScriptReference/Object.DontDestroyOnLoad.html
Unity loads the scene for 0%-90% and then the final 10% is for the scene activation. (So for tiny scenes like that it will load to 90% within one frame.) I would recommend perhaps lerping the fill amount so that it will smoothly increase upwards and look nicer overall.
A differente way... Create a scriptable object to keep the scene name intended to switch. Create generic Scene with a method in Start that will read the scriptable object to get the scene name and call a load scene.
Man, you have original way to do even simple things. I used prefab as scene loader but yours is much better... I could never thought to use new scene to load another scene... hahaha That's why, even when topic seems to be known, it's better to watch your video!
You made this way more complicated than it needs to be. I realize you don't like CoRoutines, but you can get rid of all that delegate hackiness by just having a yield return wait until next frame in a coroutine. You're already including it, so why not use it?? Also, a dummy class just to have access to monobehaviour? You could just make it a static method on a loader class that extends monobehavior. You don't need to instantiate it to access static methods, so the method signature should be the same.
I'm glad you liked it! Actions/Delegates are super useful, I also covered them in more detail here if you want to learn more th-cam.com/video/3ZfwqWl-YI0/w-d-xo.html
The reason it's at 90% isn't because of some fancy 90% loading frequency. (this will come later) Its cause you preset the loading bar to load in at 90%. I would maybe suggest this line on your LoadingProgressBar class // Awake image = transform.GetComponent(); image.fillAmount = 0f; That way you can be sure to start at 0f load fill. . . . AND you need to add the LoadingProgressBar script to your image. This might be off camera, but is also not added in the code download.
I've been playing around with this, and I'd say (Unitys Code is broken.) It gets only to 90%. if you allowActivation to be false, it won't even finish the load and have to run a >= 0.9 as presented in this documentation. docs.unity3d.com/ScriptReference/AsyncOperation-progress.html The isDone never gets sets to true. (With activation) I think maybe you could do an additive scene, and then set to 100% and fade in and out to swap scenes. With a fade image covering your background scene. BUT then you have to account for a scene being loaded, but not ready and not running, sounds and gameplay, SUCH as most games do anyways. Overall its a bad part on Unity.
Yeah I tried many things to try to understand how unity breaks scenes apart and I just couldn't do it. I made a script that created thousands of game objects on start, went 0 to 90; Tried creating textures and copying millions of pixels, 0 to 90; Tried a massive scene that I imported from one of the unity graphics projects, 0 to 90; So I really don't understand how the core engine breaks scenes apart for loading.
hello codemonkey, I have question about different time scales for different additive scene. is it possible to pause or slow down a scene while maintaining 1.0f scale for another additive scene? I mainly have a normal scene in which monsters will chase players and perform tasks and a battle scene. As you can imagine I need the normal scene to pause when i enter battle scene, but when I finish battle I was to resume everything in the normal scene. Is there a way to do that?
I use this. Arbitrary, but works. if (image.fillAmount < Loader.GetLoadingProgress()) { image.fillAmount += 0.01f // depends on the size of the scene you want to load }
Hi ! Good content. Let me know, why do you use [6:34] a delegate (onLoaderCallback) while you can handle the current scene with a simple member variable like you done in KitchenChaos tutorial.
Remember there are always many ways to solve any problem, I don't remember how I handled it differently in Kitchen Chaos but there's always more than one solution.

Been watching some of your videos over the last few days, as im interested in getting to learn the Unity engine. I just wanted to say thank you so much for making these amazing videos on your channel, keep it up dude. Got one question one program do you use to create your textures for your assets in Battle Royale Tycoon ?
The code works perfectly, but I've got 2 issues. I have a main GameScene, where I switch to another scene for playing a puzzle minigame.

The other issue is that I want to implement a crossfade transition between the scenes, but I can't implement the animation in a static class.
Yup when you load a scene it will load exactly as that scene was saved, if you spawn objects dynamically and reload the scene they won't be there. You need to save that data somewhere and then load it when reloading that scene. Simplest way to save data is with a static field, alternatively you can use the same logic for saving to a file th-cam.com/video/6uMFEM-napE/w-d-xo.html
I really want to know about changing the image of canvases of all the scenes on click of a button which is present at the main menu scenes it's like applying a theme in the game but I am totally confused and there's not a single tutorial available anywhere
Hello Code Monkey, I've watched hundreds of your (awesome) tutorials, but there's one basic topic I don't think you've expanded upon much: what are the best practices for handling the relationship between scenes? For example I've never seen you use the singleton pattern that persists objects through scenes, is it because it's a bad idea? Or is it simply because your tutorials usually only have a single scene? How would you handle something as basic as moving a Player object from Scene 1 to Scene 2 while persisting some of its data? Or how would you get in Scene 2 the information that the Player entered from Scene 1 and not Scene 3? By the way I'm commenting on this video since it's the only one I could remember where you broached the topic, but if I've missed another could you point me to it?
In my own games I normally just have one Game Scene so I don't necessarily have too much direct experience with that topic. For transferring data between scenes, like which Save file to load, for that I normally just use a simple static field so that's one option. Another option is to use a game object and just mark it as DontDestroyOnLoad(); that way it will persist even as you change scenes so you can use that to transfer any data. Making that object a singleton would make it very simple. So for the player, if you have just one player you could use a static field "private Scene lastPlayerScene;" or a dedicated script to handle cross-scene references and store some regular field there.
maybe im stupid idk, but i dont understand why it works... if the line "SceneManager.LoadScene(scene.ToString());" STARTS the loading of the 2nd level, why, when it's called on the first frame of the loading-scene, the actual loading is already completed? What am i missing? In my imagination it would switch from the loading to the level scene and still do the freeze...
Yes it does freeze but it freezes on the loading scene, so it freezes while the screen is saying "Loading" which makes it clear to the player what is happening in the background. So it loads the Loading scene, waits 1 frame just to have it rendered onto the screen, then loads the final scene.
In getLoadingProgress if the asyncOperation is null then you should return 0 not 1. and you missed to add LoadingPrgress script to the progress bar image
I agree with both points.....(return 1 not 0) Otherwise it can sometimes briefly show 100% first, then drop back which looks weird. Unless we both missed something.

I have a question. I’m trying to make a level editor for my game and I want to make it where you press a button and it creates a new scene and then switches to that scene and instantantiats everything needed for the level editor. I have the level editor already finished in a separate scene but how do I make it so you click on a button and it like create a new scene or duplicates the level editor scene. I am using visual scripting and I I tried using the “create scene” unit but It won’t work, it won’t let me connect it to “load scene async” because there are no “scene manager, load scene async” units that have a scene input, they all either have an input for the scene name or build index and whenever I connect the “create scene” scene output to “set scene name” scene input. And then the scene name output from the “set scene name” unit to the “load scene async” scene name input, and then run my game. The unit just turns red and it doesn’t work. I’ve been stuck on this all day
You don't dynamically create a scene, you just make a script that runs on that final scene, and that script constructs the level. All you need is for that script to know what the level should look like. In Visual Scripting perhaps use application variables that persist between scenes
im in unity 2020 and i did all of your code that you said to do but when i press my button it goes to the loading screen fine and the bar fills all the way, but after that it just stays on the loading screen and doesnt go to my game scene. i dont know what i did wrong, so any help would be appreciated
Depends on how you're handling the enemies. If you have some kind of health system like my own then you can listen to the event when the enemy dies and trigger the scene change unitycodemonkey.com/video.php?v=tf8NhUgORQg

what version of unity? all the tutorials I have read or watched has"using UnityEngine.SceneManagement;" but my version of unity kicks out the error that SceneManagement does not exist in that namespace. I'm still in unity 4.9 - thats as far as I could upgrade without trashing my very old project
@@CodeMonkeyUnity I started this game on version 3.5 many years ago. Many many years ago. It's just something I dabble in over the years. I upgraded periodically and got to version 4.9. But when 5.0 came out and I upgraded EVERYTHING broke. The code syntax or something changed because unity spit out too many error messages for the game to even play - too many to go back and change everything. My goal is to someday finish it and it's about 3/4 of the way there. I've done builds and it plays fine so I am pushing forward with 4.9 on this project. The load time isn't so long that I need to preload or use scene management but if it was available I would
Not sure why but when I type SceneManager.LoadScene into visual studio, it doesn't like that and says "CS0117: 'SceneManager' does not contain a definition for 'LoadScene'"... Why is that?
I need help i copyed the same code and it wont work this is the code i usedusing System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.SceneManager; public class SceneSwitch : MonoBehaviour { public enum Scene { Scene 2, } public static void Load(Scene scene) { SceneManager.LoadScene(scene.ToString()}; } } Please tell me if i did anything wrong
Thanks for the great tutorial! I followed it all along but at around 13:40 I think you forgot to assign the "LoadingProgressBar.cs" Script to the loadingbar gameobject. The progressbar only seems to work because you set the "Fill Amount" to fixed 0.928. But after fixing this mistake another error occurs: When the loading scene gets loaded the progressbar is shortly 100% filled even when the initial fill amount is set to 0. Solution could be to only render the progress bar after the loading scene is fully loaded?
I've tried tons of approaches and none of them really worked, it really depends on how Unity decides to split up your scene for loading so don't think there's anything you can do to make the loading bar perfect.
the code does work for me but the loading screen stays only for 1 frame such that it isn't really loading unless you pay keen attention which I guess most players won't
If the final scene is simple and loads in 1 second the yes the loading scene will only show up for one second. If you want to add some kind of pause or wait for player input before loading the final scene then look into Scene Additive Loading.
Hey , i know it's kinda late to ask but i want to make a Boot Scene , how can i change the Loader to acomodate that , do i add the Awake function in the Loader?
What do you mean by Boot scene? The loader doesnt care what scene is being loaded, it just loads the target scene. That can be your MainMenu, your GameScene or any scene you want.
I have a question. Why my scene transition is not smooth? There's like a break in between. It will froze for like 1-2 seconds then it changes. Could it be because of my pc? My pc is on the low end btw.
The Loading scene should be completely empty so it should load almost instantly, if it is already empty then there's not much else you can remove to make it faster.
I dont want to show loading scene every time. as example scene 1 > 2 I want loading scene between, but while 2 > 3 I dont want to show loading scene. How can I do this?
I think I saw a feature where they had scenes within a scene. Can you do a sort of tutorial on scenes within a scene and maybe if it's possible to stream it in (example, as you walk closer to a town, it loads the scene with the town models and scripts)
Iver been searching for 2 days for this answer: why does my visual studio not have 'using UnityEngine.Scenemanagement' namespace? Ive given up looking.
Hey Code Monkey, It is a bit since you uploaded the video. However, I really liked your design since it since a static class. However, there is a issue with chaining levels and going fourth and back. Imagine the chain goes like that: A B C. Using your code and expanding on it wasn't difficult. The problem is, when I go from B to C, it brings me back to level A not C. Digging into it, I saw the problem. It executes the Load function but skips over the Action/Callback onLoaderCallback and repeats the previous function (e.g. OnClick) and changes the parameters thus choosing a different level. How can this be fixed?
In the script Im trying to call the Loader class to, pops an error saying that Loader doesn't exist, even tho Ive made it publica static class. Any help?
But wait, when do scenes get unloaded? I'd like to tell my scenes to load asynchronously and I could draw a loading icon, but if I am always loading through asynch, isn't that going to cause the last level to remain loaded?
Hi. Maybe this helps: “If LoadSceneMode.Single then all current Scenes will be unloaded before loading” docs.unity3d.com/ScriptReference/SceneManagement.SceneManager.LoadSceneAsync.html
Ok so what iv dose is quite different i think. I load my lvls and prototypes in from an xml scripyt. so instead iv made a list of actions to callback one at a time updating the loadbar as they complete. my question is about the update to make sure a frame update happens. how exactly dose that work? i tried to implement it but im pretty sure iv done it wrong.
The screen only refreshes when there's an update, so the LoaderCallback script has a Update and only triggers the function that will load the target scene on that first update. Its really just the bool isFirstUpdate to test if its the first update and calling the function.
Please don't use a ToString() on an enum, it really unhealthy. Just create a static class with getters for the strings you need (don't use public consts).
Well, for enums ToString is very expensive, GetName is at least two times faster. Although it's not very important if we use it once per several minutes, ie for loading scenes.
Hi! Thank you very much, the video was very helpful. I was only thinking, I'm switching from one level to another through a bool that returns true when two targets are within the trigger area (a sphere collider). I have the script and the sphere collider under a game object. So I need the trigger to load the loading scene and then load the target scene which should be the initial scene. Is there any way to work with this something like GetActiveScene().buildIndex + 1 perhaps? These level completion zones will be different for different scenes and that's not a problem since I'm not changing the script, I'm just changing the position of the LevelEndZone game object; but for each of my levels, level loaded after the loading scene is fixed atm, as I'm no calling different scenes through different buttons etc... like you are here. I would very much appreciate the help! Thank you!
I don't know who told you that but it is not true. Go ahead and test for yourself, do 1 million iterations of a private void and then a private static void and see how long they take.
Yes very useful when you use a singleton pattern since you can access functions and logic in that class without needing to keep a direct reference to it. So perfect for any class that you only have one instance of, like Loader, CameraSystem, EnemySpawner, HealthBarUI, etc.

The action is just a variable that can hold a function. So in this case the function stored in the variable gets executed when the LoaderCallback function is called.
Its a holdover for when the code becomes real. Your going to want to respond to things that happen. The actions, stand in for this. Really nicely. Now you can write a few things that respond to that action, and not have to have a list of all the functions you need to call.
Yup exactly what @Micaiah Stevens said, it gives you more options to do things when the screen refreshes. You could store the target scene in a variable instead of an Action and load that target scene, that would work but would be limited to just loading a scene and nothing else. But with an action you could for example write to a log "Started Loading Scene " + scene; or play a sound effect so the player knows the scene is loading or anything you can think of.
How so? The video is titled Scene Manager and the video deals with making a Scene Manager to manage how you load various scenes. What is a Scene Manager to you?

Nice demonstration of the unity3D loading progress bug ! :P
Really nice video on the Load Scene and how to chain events together to make sure you have your assets loaded.
The reason it's at 90% isn't because of some fancy 90% loading frequency.
(this will come later)
Its cause you preset the loading bar to load in at 90%.
I would maybe suggest this line on your LoadingProgressBar class
// Awake

That way you can be sure to start at 0f load fill.

I’m trying to make a level editor for my game and I want to make it where you press a button and it creates a new scene and then switches to that scene and instantantiats everything needed for the level editor. I have the level editor already finished in a separate scene but how do I make it so you click on a button and it like create a new scene or duplicates the level editor scene. I am using visual scripting and I I tried using the “create scene” unit but It won’t work, it won’t let me connect it to “load scene async” because there are no “scene manager, load scene async” units that have a scene input, they all either have an input for the scene name or build index and whenever I connect the “create scene” scene output to “set scene name” scene input. And then the scene name output from the “set scene name” unit to the “load scene async” scene name input, and then run my game. The unit just turns red and it doesn’t work. I’ve been stuck on this all day
You don't dynamically create a scene, you just make a script that runs on that final scene, and that script constructs the level. All you need is for that script to know what the level should look like. In Visual Scripting perhaps use application variables that persist between scenes
im in unity 2020 and i did all of your code that you said to do but when i press my button it goes to the loading screen fine and the bar fills all the way, but after that it just stays on the loading screen and doesnt go to my game scene. i dont know what i did wrong, so any help would be appreciated
For some reason I get a NullReference when I run the game. I checked my scene name and the name of the button that has the GameSceneUI script
On what line? Use Debug.Log to find out what is null unitycodemonkey.com/video.php?v=5irv30-bTJw
@@CodeMonkeyUnity I figured it out. It was a really simple mistake. I never attached your Button_UI script to the button. Thanks for the help
How can I trigger next scene after last enemy is destroyed?
Depends on how you're handling the enemies. If you have some kind of health system like my own then you can listen to the event when the enemy dies and trigger the scene change unitycodemonkey.com/video.php?v=tf8NhUgORQg
Hi,
How can i pass the scene names dynamically ?
scenes = new string[]{"Assets/*unity"}
Something like this.
pass to where? One way to hold data through scene changes is make it static
Or keep the data in some object that has DontDestroyOnLoad();

thank you
what version of unity? all the tutorials I have read or watched has"using UnityEngine.SceneManagement;" but my version of unity kicks out the error that SceneManagement does not exist in that namespace. I'm still in unity 4.9 - thats as far as I could upgrade without trashing my very old project
That version is ancient, why are you using it? Unity is free, just download the latest LTS version
@@CodeMonkeyUnity I started this game on version 3.5 many years ago. Many many years ago. It's just something I dabble in over the years. I upgraded periodically and got to version 4.9. But when 5.0 came out and I upgraded EVERYTHING broke. The code syntax or something changed because unity spit out too many error messages for the game to even play - too many to go back and change everything. My goal is to someday finish it and it's about 3/4 of the way there. I've done builds and it plays fine so I am pushing forward with 4.9 on this project. The load time isn't so long that I need to preload or use scene management but if it was available I would
Not sure why but when I type SceneManager.LoadScene into visual studio, it doesn't like that and says "CS0117: 'SceneManager' does not contain a definition for 'LoadScene'"... Why is that?
Do you have a different class also named SceneManager?
You should be using UnityEngine.SceneManagement.SceneManager
I need help i copyed the same code and it wont work this is the code i usedusing System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManager;
public class SceneSwitch : MonoBehaviour {
public enum Scene {
Scene 2,

Please tell me if i did anything wrong
Thanks for the great tutorial! I followed it all along but at around 13:40 I think you forgot to assign the "LoadingProgressBar.cs" Script to the loadingbar gameobject. The progressbar only seems to work because you set the "Fill Amount" to fixed 0.928. But after fixing this mistake another error occurs: When the loading scene gets loaded the progressbar is shortly 100% filled even when the initial fill amount is set to 0. Solution could be to only render the progress bar after the loading scene is fully loaded?
I've tried tons of approaches and none of them really worked, it really depends on how Unity decides to split up your scene for loading so don't think there's anything you can do to make the loading bar perfect.
the code does work for me but the loading screen stays only for 1 frame such that it isn't really loading unless you pay keen attention which I guess most players won't
does anybody know the solution?
If the final scene is simple and loads in 1 second the yes the loading scene will only show up for one second.
If you want to add some kind of pause or wait for player input before loading the final scene then look into Scene Additive Loading.
@@CodeMonkeyUnity I managed to add a timer in the loader callback script. Here's how.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class LoaderCallback : MonoBehaviour
{
bool isFirstUpdate = true;
float loadingScreenCountdown = 60 * 3;
void Update()
{
if (isFirstUpdate && loadingScreenCountdown == 0)
{
isFirstUpdate = false;
Loader.LoaderCallback();
}
else
{
loadingScreenCountdown -= 1;
}
}
}
@@kinda_history_nerd This is not ideal, your timer is frame dependent which means on a faster machine it will count much quicker.
I was wondering how to add a fading effect before the loading screen. Any Idea ? Thanks !
You could have a simple Image in the UI stretched to occupy the whole screen then animate the alpha and when it gets to 1 you start actually loading.
Hey , i know it's kinda late to ask but i want to make a Boot Scene , how can i change the Loader to acomodate that , do i add the Awake function in the Loader?
What do you mean by Boot scene? The loader doesnt care what scene is being loaded, it just loads the target scene. That can be your MainMenu, your GameScene or any scene you want.
I have a question. Why my scene transition is not smooth? There's like a break in between. It will froze for like 1-2 seconds then it changes. Could it be because of my pc? My pc is on the low end btw.
The Loading scene should be completely empty so it should load almost instantly, if it is already empty then there's not much else you can remove to make it faster.

I dont want to show loading scene every time. as example scene 1 > 2 I want loading scene between, but while 2 > 3 I dont want to show loading scene. How can I do this?
I think I saw a feature where they had scenes within a scene. Can you do a sort of tutorial on scenes within a scene and maybe if it's possible to stream it in (example, as you walk closer to a town, it loads the scene with the town models and scripts)
Additive Scene Loading is something I'd like to cover in the future but first I need to do some research since I've never actually used it.
Is there any way I could call those functions on Unity's own Button's OnClick() function?
Sure, you can call the static functions from anywhere
@@CodeMonkeyUnity but in the inspector I can't find the function
When I import the package of this video in the scenes "MainMenu" and "GameScene" there is a "Missing prefab". 2019.2.18f1
Iver been searching for 2 days for this answer: why does my visual studio not have 'using UnityEngine.Scenemanagement' namespace? Ive given up looking.
the correct name is UnityEngine.SceneManagement;
Unity freezes after loading scene 2 and it says "not loaded" in the hierarchy
Can you load the scene normally by double clicking it? Any errors in the console?
Hey Code Monkey,
It is a bit since you uploaded the video. However, I really liked your design since it since a static class.
However, there is a issue with chaining levels and going fourth and back.
Imagine the chain goes like that: A B C.
Using your code and expanding on it wasn't difficult.
The problem is, when I go from B to C, it brings me back to level A not C.
Digging into it, I saw the problem.
It executes the Load function but skips over the Action/Callback onLoaderCallback and repeats the previous function (e.g. OnClick) and changes the parameters thus choosing a different level.
How can this be fixed?
Use Debug.Log to understand what your code is doing, seems like you have something in your code running in the wrong order
In the script Im trying to call the Loader class to, pops an error saying that Loader doesn't exist, even tho Ive made it publica static class. Any help?
It turns out I had to have both scripts in the same folder hehe oops
I dont like this one boss. seems a bit messy
In which gameobjects do u put the first two scripts "Loader" and the "GameSceneUI" ?
Loader is a static class and you don't put it in any object
i keep getting error CS1061, "transform" doesnt have a definition for "find". Please Help.
The function name is Find()
A tutorial about Additive Scene load Or multi scenes ?
I want Battle scene to be additive to MainScene. didnt figure out yet how to do that.
But wait, when do scenes get unloaded?
I'd like to tell my scenes to load asynchronously and I could draw a loading icon, but if I am always loading through asynch, isn't that going to cause the last level to remain loaded?
Hi. Maybe this helps: “If LoadSceneMode.Single then all current Scenes will be unloaded before loading” docs.unity3d.com/ScriptReference/SceneManagement.SceneManager.LoadSceneAsync.html
There is also: SceneManager.UnloadSceneAsync

Ok so what iv dose is quite different i think. I load my lvls and prototypes in from an xml scripyt. so instead iv made a list of actions to callback one at a time updating the loadbar as they complete.
my question is about the update to make sure a frame update happens. how exactly dose that work? i tried to implement it but im pretty sure iv done it wrong.
The screen only refreshes when there's an update, so the LoaderCallback script has a Update and only triggers the function that will load the target scene on that first update.
Its really just the bool isFirstUpdate to test if its the first update and calling the function.
@@CodeMonkeyUnity ok yeah i figured it out. i didnt force it to run through update. i got it now. thanks
Ahhh...well it started simple enough
Please don't use a ToString() on an enum, it really unhealthy. Just create a static class with getters for the strings you need (don't use public consts).
Why do you say enum.ToString(); is unhealthy and why do you dislike public consts?
Well, for enums ToString is very expensive, GetName is at least two times faster.
Although it's not very important if we use it once per several minutes, ie for loading scenes.
Volume needs to be louuuder......
How would i reload the current scene using this Scene Manager?
Just Load the current scene. So in this case if you're in GameScene and you want to reload just call Loader.Load(Scene.GameScene);
Hi! Thank you very much, the video was very helpful. I was only thinking, I'm switching from one level to another through a bool that returns true when two targets are within the trigger area (a sphere collider). I have the script and the sphere collider under a game object. So I need the trigger to load the loading scene and then load the target scene which should be the initial scene. Is there any way to work with this something like GetActiveScene().buildIndex + 1 perhaps? These level completion zones will be different for different scenes and that's not a problem since I'm not changing the script, I'm just changing the position of the LevelEndZone game object; but for each of my levels, level loaded after the loading scene is fixed atm, as I'm no calling different scenes through different buttons etc... like you are here. I would very much appreciate the help! Thank you!
You should null the asyncOperation as well in some point
since it's a local variable of a coroutine, it should become null after the coroutine is ended
I think using too much static functions/methods may decrease game performance.
Why do you think that? There's no inherent cost to making a function static.
Code Monkey people say it decrease you game performance if used static more
I don't know who told you that but it is not true.
Go ahead and test for yourself, do 1 million iterations of a private void and then a private static void and see how long they take.
Haha ok....thank you for this tut.
Static function can be called from any script right? Mainly used for Singleton and one instance right?
Yes very useful when you use a singleton pattern since you can access functions and logic in that class without needing to keep a direct reference to it.
So perfect for any class that you only have one instance of, like Loader, CameraSystem, EnemySpawner, HealthBarUI, etc.
You don't mention how to link the buttons
What do you mean? You can call the function from anywhere

Water Cat I can understand you but it is hard for me. Is it possible to rewrite it?
@@arsylgames ok no problem thenx meny time wean comments is hard understand thenks for telling that I will make more clear
@@arsylgames ok now thing my question more clearly
Why do you use actions? I can`t really understand what they exactly did.
The action is just a variable that can hold a function.
So in this case the function stored in the variable gets executed when the LoaderCallback function is called.
Its a holdover for when the code becomes real. Your going to want to respond to things that happen. The actions, stand in for this. Really nicely.
Now you can write a few things that respond to that action, and not have to have a list of all the functions you need to call.
Yup exactly what @Micaiah Stevens said, it gives you more options to do things when the screen refreshes.
You could store the target scene in a variable instead of an Action and load that target scene, that would work but would be limited to just loading a scene and nothing else.
But with an action you could for example write to a log "Started Loading Scene " + scene; or play a sound effect so the player knows the scene is loading or anything you can think of.
Doesn’t even work smh
What doesn't work?
title doesn't match the video content
How so? The video is titled Scene Manager and the video deals with making a Scene Manager to manage how you load various scenes.
What is a Scene Manager to you?
