Hey, for anyone new to godot using a newer version (like me), in case it looks like the code isnt working after some moment in the video, try to check if the code hasnt changed how some things are called.
Heres some examples:
-"export" is written as "@export" now
-"InputMap.get_action_list" became "InputMap.action_get_events"
-"scancode" now is "keycode" (yes it applies to "get_scancode_string" too)
-"is_action_just_pressed" didnt change name (at least not in the version I'm using)
Appreciated!
also, if your interact input accepts physical input (like "E"), you have to scan for physcal keycode, like so:
keyname = OS.get_keycode_string(action.physical_keycode)
Another thing, if you guys are trying to set the path following platform in the tween_property it's not
"unit_offset" anymore, it's "progress_ratio"
@@maks-yn5xg for some reason it shows just "[]" instead of the key "E"
@@binyot5505 probably they changed it again in godot 4.2, so maybe look into change log for anything about inputs
This tutorial is really awesome. Your humor mixed with learning keeps it interesting! Please make more!
Really like your humor, please go on and do more of these tutorials! :)
Well explained, good pace, scalable, humorous. I love it!
Very nice tutorial. I like how scalable and efficient this is for larger games. Never knew you can define custom class names :D
dude keep making these videos, you're doing incredibly well
Your tutorials are not only informative, as they are absolutely hilarious!
i try... to make them informative, I mean
Fantastic tutorial. Just what I needed and I've been working for hours to learn how to do this. Thank you so much!
I really enjoyed this tutorial. Thank you so much Nagi. I'm working with Godot 4 so I had to look up and translate a few things but it's fun. You're a good instructor.
Thanks that means a lot. Also it means I'm doing something right! I'll be posting Godot 4 tutorials soon, working on a different type of video right now so stay tuned :)
@@NagiDev Yes, thank you. I can't for the life of me figure out how to get the interact Key to return to the player in Godot 4. (Sub'd btw) I need to slow down your tutorials to 75% and they work great. Especially how you created the door with the bones.
@@GaryParkin Can you please explain what you mean by making the interact key return to the player?
@@NagiDev The code in get_prompt around 3:20 where you use InputMap.action_get_events(prompt_action). I can get the key by using InputMap.action_get_events( actions ), but OS.get_scancode_string is no longer valid. It doesn't connect to any variable coming from InputMap.
I have a question pending in the forms. The closest I've gotten is var actions = InputMap.get_actions().find(prompt_action)
i like ur videos, im a new sub from the fps mouvement video, continue : )
One of the best paced video tutorials I've ever seen. Thank you for respecting the viewers time. It allows people like me who used other engines to quickly pickup what the new function names, general behaviors, and workflows are without having to lug through all the zero-to-hero overhead the docs and other tutorials do. Even with the tutorial being for Godot 3, its taken less time to translate it to Godot 4 than it would to listen to most others drone on about its principles, long wind up jokes, and uncut clicking and loading.
Cool Tutorial, and love that funny and laid-back style of yours! Keep up that good work 😄
Amazing Godot tutorial, I have not see something like this for a long time
I have watched 30 seconds and let me tell you. Your video editing hilarious and your English is very good nice tutorial!
Awesome video and helped clear many things for me as a Godot beginner. Thanks
bro you deserve 100k atleast... thank for such an amazing video
really i was out of my mind and then i see this it amaze me.. thank for tutorial and sharing you knowledge
with us i really means a lot (and also i dont comment on some one's video you are the first one )thank you
Looking good my man! Can't wait for that ice wall tutorial! :D
One ice wall tutorial coming right up!
THIS WAS SOOOOO HELPFULLLLLL
I did interact with the subscribe button. Entertaining tutorial format.👍
Did it change color?? (Asking for research purposes 🧐)
@@NagiDev It did! Unbelievable, but it did! It not only changed the color, it also changed its label - slightly at least.
I am very impressed by that. Blew my mind. Made POOOF in my head.
Much subscribe. Very liked. So upvoted. Just wow.
@@dueddel I think we should share this magic with others! Time to bamboozle the world (in a good way)!
Why is your channel so underrated!?
Maybe because of my inconsistent upload schedule
🙏 very good tutorial
Very nice tutorial, really a good work!
Very useful video, keep the good work.
One aspect in Godot and in 3d I'm personally struggling of is light, in particular interior light.
I find very difficult set the enviroment light and in case of rooms the interior light.
I'm glad you found the video useful. As for interior lighting, even I'm a beginner at that. I'll try to post something if I get it right, but for now all I can suggest you is to play around with every setting in the environment settings as possible ( at least that's what I do ).
Amazing!
Love you tutorials ♥
Good stuff, thanks. I, for one, welcome the godot4 stuff.
This is really awesome tutorial
I don't use Godot but this is comedy gold! nice tutorial
which engine do you use?
@@VickylanceMedia well I use max2d for mobile but I'm thinking of moving to GDevelop
@@AeroZone Nice never heard of Max2d interesting
Yea it's a really cool app for mobile devs
I had been chilling for a while🤣
Really help full
For anyone using Godot 4:
- Instead of "InputMap.get_action_list(action)" use "InputMap.action_get_events(action)"
- Instead of action.scancode use "key_name = OS.get_keycode_string(action.physical_keycode)"
ty
Awesome!
drink your cookies and eat your milk, perfect tutorial only a little fast and one time you didn't said what you did and I got a mistake but i found it :D
Okay, I'm still pretty new to this. I'll try to make less mistakes next video! Thanks!
You are awesome. Thank you
THANK YOU SO FUCKING MUCH I WAS TRYING TO FIGURE THIS OUT LIKE ABOUT 2 HOURS
he he happy fo help!
THB some (not all) jokes in the video were a bit irritation for me (maybe I'm too old for it).
But this channel is definitely very underrated: great demonstration, polished results, simple explanations.
Thanks. Will wait for more videos.
I know my jokes are bad and I try to keep them to the minimum. I'm glad folks are finding my videos useful and I'll try to post the next video asap.
Cheers!
please tell me u are still working on the fixed godot 4 vers of this vid, you are the only person that explains well and has what im looking for😭
I am lol
@@NagiDev thank god 🙏🙏🙏
Solid!
Hey Nagi! Thanks for this tutorial, but im having some difficulties with the Interactable type, i'm on version 4.2.2. it just says "could not find type "interactable" in the current scope . if you know how to fix this, please let me know. Thanks!
Edit: Nvm, it somehow just worked lol. But now when I place my crosshair over my cube/button it doesn't say anything
thank you bro
can i make a suggestion you go really fast in these tutoirals and it makes it hard to follow sometimes i dont know if anyone else has the same issue but if you could slow it down just a bit that would be nice
Yeah, a few people have pointed that out and I've tried to slow down a little on my newer tutorials for Godot 4. Please let me know over in those videos if the speed still feels too fast. I'll keep on working on the speed of my tutorials.
at 3:25 line 13 Im getting an error message "Static function "get_scancode_string()" not found in base "OS"." Does anyone have a fix. (I am using godot 4.0)
This tutorial was made for Godot 3, I'll be posting one for 4.0 soon
I've changed some of the strings / nodes etc. so you may need to update to your own project or to match the ones used by Nagi in the tutorial; hope this helps. Thanks to Nagi for a great tutorial and the humour, this was the only code I was able to get to work with a few tweaks, while trying to learn Godot 4, first week trying the engine or game making for that matter :D haven't been able to get the platform working in 4 yet as tween code needs updating, sure I'll figure it out.
All thanks to Nagi (www.youtube.com/@NagiDev) for his tutorial, I just updated for Godot 4
####Interactable .gd - script
extends StaticBody3D
class_name Interactable
signal interacted(body)
#prompt message i.e. keymapping to press
@export var prompt_message = "Interact"
#Keymapping (Input mapping, project settings)
@export var prompt_action = "Interact"
func get_prompt():
var key_name = ""
for action in InputMap.action_get_events(prompt_action):
if action is InputEventKey:
key_name = OS.get_keycode_string(action.keycode)
return prompt_message + "

func interact(body):
#Print to console for debugging - optional
# print(body.name, " Interacted!")

@export var open = false
var playback = null
func _ready():
playback = $AnimationTree.get("parameters/playback")
func toggle_door(_body):
open = !open
if open:
playback.travel("DoorOpen")
else:
playback.travel("DoorClose")
####InteractRayCast3D - script
extends RayCast3D
@onready var prompt = $Prompt
func _ready():
add_exception(owner)
func _physics_process(_delta):
prompt.text = ""
if is_colliding():
var detected = get_collider()
if detected is Interactable:
prompt.text = detected.name
prompt.text = detected.get_prompt()
if Input.is_action_just_pressed(detected.prompt_action):
detected.interact(owner)
Note there are some compatibility updates required for 4.0 like updating 'extends nodes' to what you may have used, updating player.gd e.g. removing move_and_slide() arguments and updated functions. I'd created my own code at first but struggled with getting doors to work using alternative methods (different types of doors than the ones used in this tutorial but close enough for this guide to work with updates and without using bones.
@@Xeno-Morpehus you are amazing!
@@Xeno-Morpehus Thanks i was really stuck and this helped me
@@Xeno-Morpehus you saved me, thanks man!
I have interacted with the like and subscribe buttons
what do you think about 3D in godot !
I like games like puppet combo games or fear to fathom
do you think godot can handle this type of games !
many say it will lag and bad performance
so i really want to know what do you think !
your tutorials are really helpful keep up
Looking at the gameplay of fear to fathom, I don't think you'll have any problem making a game like it. The only aspect I've seen Godot struggle in is handling a huge number of physics objects (pretty rare case for most game projects) and even that can be solved by using low level languages to handle those parts. So, yeah, go ahead and give Godot a try! You would have a lot of fun ;)
HOW DID YOU CREATE TEXT, or that is 3d object?
btw, god damn cool video editing, wow
Pls how did you set up the lighting here. It looks simple and clean.
I just use an environment node and a directional light. Then I tweak a bunch of settings for both to get the look I like. You can look into the project to see what settings I change. Also, I change a few rendering options in the project settings.
@@NagiDev Oh. Just realized the project was actually available to download. Thanks a bunch.
Could you do one for godot 4?
Its confusing now.
Already on it, will post one soon
Hello i need some help!! i have been trying to find a way on how i can trigger the doalogue box when i collide with something can u please help me out or tell me how i can achieve that
Hey!
You can add an Area node to the object with the CollisionShape slightly larger than the object's CollisionShape. Then trigger the dialog (dialog.start) whenever a bodyEntered signal is triggered on the Area node.
@@NagiDev I did but i seem to get the error “no dialogue data” also i had some other questions is there anyway i can reach i tried to on your twitter but it seems like i can’t dm you there
If you're trying to use the Dialogue Node addon like I did, I suggest you follow my tutorial on that. I think you haven't added the dialogue file through the inspector.
@@NagiDev yea i just noticed 😭😭😭 TYSM also one last question how can i trigger different starting nodes using one dialogue box or do i add different dialogue boxes
@@ruumroom. You can add any number of start nodes to one dialogue file, each must be assigned a unique ID. In the dialogue, while calling the start function, provide the ID of the start node you want to use. Example: start("MY_UNIQUE_ID")
por favor, haz tutoriales de Godot 4! o una serie para un diario de desarrollo de juegos, de un juego independiente completo (tamaño pequeño)
Estoy trabajando en un diario de desarrollo. ¡Lo mostraré muy pronto!
I still haven't figured out how to Import a Object in Godot Scene
Can you make a version for godot 4 plz
Definitely, I'm already working on it
This is a great tutorial but I'm currently a bit stuck at 3:28 where im just getting errors saying that static function "get_action_list()" not found in base input map. I assume this is because I'm working in godot 4 instead of 3 but do you have any idea of what code to write instead?
Wait nevermind I figured it out thanks to @Xeno-Morpehus
could you do this for godot 4? its really nice but im using 4
Yes, I'm already in the process of making an updated tutorial
For some reason once the animation is activated it won't stop?
Check the animation player, the animation track shouldn't be set to loop.
@@NagiDev thanks for the comment, though I did end up fixing it and Im pretty sure it was the animation loop being enabled so thanks
This tutorial was great btw it's allowed me to implement so many other things into my game
i need help, i get "is_action_just_pressed: the InputMap action "F" doesn't exist." and i dont know what to do
you'll have to go to the Input Map in project settings and define an new action there. Then you can use the name of the action in your is_action_just_pressed function.
Tried adding the prompt.text = "" but I receive an error about the Identifier prompt not being declared
Check if you've spelt the variable the same as the onready declaration. Also, did you declare it in the first place?
@@NagiDev I didn't thank you
So is the issue resolved?
@@NagiDev yea
Invalid set index 'text' (on base: 'null instance') with value of type 'String'. me falla eso me sale :(
Can you please check if you added the Label node in your scene and that it's not renamed and/or placed as a child of a different node than the one shown in the tutorial?
yes is perfec nodesl@@NagiDev
what's the name of the game that played at the start of the video? I really wanna make interactable buttons like that
Outer Wilds. It's an amazing game!
hello, can u make this tutorial for godot 4
Hey! Definitely, I'm working on remaking all my Godot tutorials for Godot 4. Stay tuned!
ok so I commented earlier but since then deleted it because I fixed it.
however, now when I attach class_name Interactable to multiple scripts I receive the Class "Interactable" hides a global script class
is there a way to fix this?
You can only assign a class_name to one script. If you want to have multiple scripts with the interactable functionality, you'll have to inherit from the Interactable class.
Hello, I'm currently using the Godot 4.1 version. I've got some issues even though I used the same code (with the corrections on the things that changed). For example I can't figure out why, when I detect the object, it just gives me the prompt message, but not the key code. Another issue I have is that the character still moves when the dialogue is displayed, don't know why. Could you help me with that?
Hey! The prompt message not showing the key in Godot 4 is probably because you set the input map to use physical keys (which is default in 4).
You will have to edit Interactable.gd script to have:
for action in InputMap.action_get_events(prompt_action):
if action is InputEventKey:
key_name = action.as_text_physical_keycode()
As for the character still moving, there could be a number of reasons. Please feel free to contact me on Discord or Twitter so I can help you out.
Hope this helps!
@@NagiDev maybe I can send you the code on discord so you can help me out! Do you have a link so that I can contact you, or do I find you with the same name? Sorry to bother, it's just I'm doing a project for my degree, and I want to understand better in order to fix everything
@giorgiaalloisio0309 you can contact me on Discord at nagidev
@@NagiDev Thank you for this!! i was actually stuck trying to figure this out and scrolled down a but I thin you should put this change into the description or pin it XD
@DwarvenDoesThings my dude I'm working on remaking the whole video for Godot 4...
The platform doesn't want towork :( the method create_tween() is not declared in this current class
Are you using Godot 3.5?
@@NagiDev no but 3.4.4 is there such an huge difference :(
@@crabbite3093 I'm using the new tween system, which was introduced in 3.5 You can update to 3.5 if you want, it's totally worth it
Alternatively, if you want to stay with 3.4, you can add a tween node in the platform scene, and run that tween instead.
@@NagiDev thx, i will try that
Any idea how to get this working with Godot 4?
Hi, yes, I'm currently working on an updated tutorial for the same. The video would be up in a few weeks.
can u tell us how we can implement the dialog box using dialogic
I'm not sure what format Dialogic uses to store dialog data. Even if it was JSON data (like in my add-on), I don't think the two would be compatible. Sorry :/
im stuck in a specific part of this it keeps say "invalid call. non existant function 'interact' in base 'static body (button.gd)' the button.gd is the interactable script i just named it wrong.
You'll have to make sure the static body you're interacting with has a script, and that script has an `interact` function.
@@NagiDev thank you for replying but the problem persists, the object has the script attached but still whenever i click the interact button, it kicks me out and gives me the error.
@@sadisticallyme8379 Have you excluded the raycast from detecting the player itself?
You can debug by printing the name of the collider to check which object you're actually interacting with.
print(raycast.get_collider().name)
@@NagiDev ah yes nevermind me i went thru the script and found a spelling mistake I wrote interact instead of Interact so the hole thing just didnt work.
my ray isn't going up and down its only going left and right
did you add the raycast as a child of the head node?
@ yes but i solved the problem it was just my camera control script being bad
oki doki
Are you using the android version of godot?????
not in these tutorials, but yes, I do work on it sometimes
Hi I have a problem with the get_prompt() function.
sure, lemme know the full problem and I'll try my best to help you
@Nagi Everything's is good I'm just a bit distracted
I have to assume based on the comments that this actually worked at some point, but it absolutely does not anymore. Gotta love Godot bragging about all the features they add, and never mentioning all of the things they needlessly changed or removed that render a decade worth of tutorials valueless.
Hi, I have mentioned it in the title: this tutorial is for Godot 3. Godot developers maintain older versions of their engine for a while since people working on long game projects can't afford to switch to the next major version. I'm sorry I haven't posted a tutorial for Godot 4 yet, but this tutorial is still useful for people working with Godot 3.
Cheers!
@@NagiDev I apologize if you thought I was complaining about your tutorial. My complaint was about Godot needlessly changing minor things and breaking basically every tutorial and answer you can find online.
It's alright Ken. I understand your point but it's a normal thing for most software to change in every major update. Blender 2.8 comes to mind as an example. But being a long time user of both software I managed to update my knowledge of Blender and Godot without any trouble.
Now, I understand this can be frustrating for beginners and I am here just to help with that. I have a bunch of tutorials in the works for the latest version of Godot. I just need some time to put them all out, so stay tuned!
Aw man… thx for bringing this to my attention before I apply it to my game.
