#unity #csharp #tutorial
Lemme explain some of you guys issue with the tutorial.
1-)A lot of people complaining about bullets hitting something and that object dissappears. Thats because bullet script set like that and you can change that part.
void OnCollisionEnter(Collision collision)
{
Destroy(collision.gameObject);
Destroy(gameObject);
}
2-)Bullets flying up or going to another direction. Thats because gun in the video points different from your gun. You can solve that by changing your BulletSpawnPoint's rotation value depending on your characters rotation.
How would i fix problem number 2?
@@Frowgster if you see in the video he changes the axis XZY on the blue arrow that is the z axis...and rotates on -90 you can change te direction doing this. On the script you instantiate the bullet on this axis and thats why the bullet goes out there. Check those 2 things
how to fix number 1 when i change the part it doesnt work.
The reason its destroying everything is because oncollisionentier that means as soon as it hits a collider it destroys it i recommend adding a tag and modifying your script to match the following:
if (collision.gameObject.CompareTag("Destroyable"))
{
Destroy(collision.gameObject);
Destroy(gameObject);
}
You can make the tag whatever you want as long as you change it inside script and inspector
@@ZifowkBrother can you explain it a bit in depth, please? like I want to destroy an object named Enemy only so what changes do I have to make can you please tell me if you don't mind?
Short, simple and clear. Good job
Thank you so much! I am a noob, and after 1 week of research and trial and error I finally got my gun to work thanks to you!
meanwhile some dude have 10 hour tutorial.....
and i watched it even i am a good game developer but im weak in gunss.. little so i watched a 3hr video and i litterally not learned a single thing. i just can just make a model but this person is a lifesaver
@@Hecker634 those Loong hour video is usually didnt teach you anything beside giving inspiration. Bad tutorial for beginner lol. But for us in the phase of learning, it can show us something new
@@skarhabekgreyrukh8601 k...... thx bro
Thank you so much for this, it relieved much frustration for this noob. After I applied this script my bullets worked but destroyed everything they touched, so I modified with a simple if/else so they only kill the objects tagged as Enemy. It doesn't sound like much, but I am feeling very pleased :)
tomorrow i gona make tutorial for the gunshot and enemy subscribe to see it.
straight to the point, very good tutorial, thank you so much soldier

I'd like to be specific with bullets it can be a 5.56, 7.62, 12.7mm, 20mm, 30mm so I made a code for each bullet. The higher the caliber the more powerful the impact
using System.Collections;
using UnityEngine;
public class Bullet : MonoBehaviour
{
public float speed = 10f;
public float maxDistance = 100f;
public LayerMask collisionMask;
public ParticleSystem impactParticles;
public AudioClip impactSound;
public float destroyDelay = 10f;
private AudioSource audioSource;
private Rigidbody rb;
private void Start()
{
rb = GetComponent();
rb.velocity = transform.forward * speed;
audioSource = gameObject.AddComponent();
audioSource.spatialBlend = 1f;
audioSource.minDistance = 50f;
audioSource.maxDistance = maxDistance;
audioSource.playOnAwake = false;
audioSource.clip = impactSound;
StartCoroutine(DestroyAfterDelay());
}
private void FixedUpdate()
{
// Move the bullet using physics forces
rb.velocity = transform.forward * speed;
}
private void OnCollisionEnter(Collision collision)
{
// Check if the collision object is in the collision mask
if (collisionMask == (collisionMask | (1
and this is a good straightforward tutorial video instead of 10 minutes of nonsense
As always GOD mode!
Thanks for making things so simple. Everyone else made it over complicated! I have one question if you wouldn’t mind answering. What if I wanted to spawn different style bullets with different keys? Thanks for your time either way.
Create a prefab for each type of bullet. Then In Gun script, create a GameObject field for each bullet prefab. Now just shoot the desired bullet with desired key.
@@Unity3DSchool perfect! This is exactly what I was going to try and do first!
this is the easiest tutorial to follow ever. and also the most useful one for me :)
tomorrow i gona make tutorial for the gunshot and enemy subscribe to see it.
Thank you bro! Works just fine!
this was the best tutorial that i have ever watched you are really good congrats i am very impressed
i agree !
tomorrow i gona make tutorial for the gunshot and enemy subscribe to see it.
It worked for me. Thank you!
@Unity3D School do you have a tutorial for damage?
Im trying to make a damagemanager so i can modify and manage various enemies and weapons and its hard to understand how they correlate with the manager..
How to add a shoot limit plz
I am making a 2d game and I switched everything with 2d. However, bullet doesn't move. Just spawns without motion.
change the code to instead of rigidbody do rigidbody2d and add a rigidbody2d on the bullet instead
@@TheRocketTurtle I already was doing that
I have the same problem did you find the reason why?
This helped me a lot thank you
thanks so much this was really helpful (im subing)
Thank you so much. Your video helped me upload my video game today
Idk why but tbe gun only shoots when i hit space
I tried fixing by changing things in the scripts but nothing works
Any tips ?
Great tutorial!
Thanks! I needed something simple and this did the trick!
tomorrow i gona make tutorial for the gunshot and enemy subscribe to see it.
i just realize making fps game in unity are more easier than making in roblox
How does it have to look like for 2D shooting upwards?
Thank you a lot mate
can someone tell me why my bullets are shooting not cuz of LMB But the Spacebar
u need to change this "if(Input.GetKeyDown(KeyCode.Space))" to this "Input.GetMouseButtonDown(0)"
so perfect tutorial
thank you so much
THANK FOR TUTRIAL IT HELPS ME TO MAKE I OWN GAME
How we had texture To bullet ?
And the gun ?
Awesome and simple! Thanks. Do you know how it would be if I would like to fire in bursts?
tomorrow i gona make tutorial for the gunshot and enemy subscribe to see it.
OMG. Desverves a sub. So simple but yet it works
Bro I did all but when I press space bar the cylinder disappears and no shooting happens?
Make sure you attack the destroy script with the bullet not the gun
tomorrow i gona make tutorial for the gunshot and enemy subscribe to see it.
not working!
it is deleting the gun itself...
tomorrow i gona make tutorial for the gunshot and enemy subscribe to see it.
You need to move the bullet spawn point out of the gun
And rotate it to the other direction
thanck uoy.
Thank you very very very much for that
thanks
make a video on making bullet and particle system and raycast etc
I don't understand why I have this error: NullReferenceException: Object reference not set to an instance of an object.
Can you help me?
when I press space bar the cylinder disappears and no shooting happens?
tomorrow i gona make tutorial for the gunshot and enemy subscribe to see it.
thanks for this tutorial. What im struggling with is i want to make the bullets go out as long as i hold the mouse button. My gun is full auto which shoots 750 rpm so id expect the bullets to come out rapidly. Any helps would be appriecated
THANK YOUUUUUUU!!!!!
It just works! Thx!
Thanks for such a great tutorial. I am making a game about throwing clothes, but when I replace the bullet ball to cloth it doesn't work.could you help me to figure out why?
Hello i like the video but when ever i try to the the bullet in the assests it wont let me it gives me an error saying you are trying to save a prefab that has a script and a lot fo other stuff can you please help me?
Wt* the scrip corrupt my camera 😂😢😅
my bullet doesn't fire when i press space, but it might be because space is already binded to jump
it isn't tried it,
wow thanks! my gun launched infinite bullets and crashed my unsaved game ive been working on 6 hours from!
ty for show when u script it so i can cppy the script but whrite it myself and understand it more
great tutorial but for some reason when i click space bar the gun and bullet dissapear and nothing shoots... why?
Move the spawner into a position so that the bullet doesn't come into contact with the gun.
thx for the tuto
It doesnt seem to work for me. In the first script I get an error. "The Local Variable "bullet" can only be used after it is declared"
Declared the variable inside the class and not in the function
Perfect, thanks you.
My gun is deleted when I press shoot button. What can be a reson?
I think you have written c# script wrong and you used destroygun to destroy the gun on the firing
Thank you
Please help, when i hit play it says invalidOperationExeption this only happens when i enable the script please help :)
What should I do if I want to regularly fire 1 time per second instead of the spacebar?
make the two line of code to shoot in a method then call it on update method by using Invoke("shotBall", 1f);
shotBall is a name i give for the method you can replace it with your own method name
this is a very good tutorial. But I have a question how to add sound to shooting
HOW TO MAKE IT SO THE BULLET DESTROYS WHEN IT HITS THE OBJECT ?
You need to write in bullet script: void update()
{
Destroy(gameObject, 3);
}
How do you attach the gun to the camera so you can aim?
When I shoot, the bullets just go up for some reason
EDIT: fixed
How did you fix it? When I press space, the gun item disappears
@@manavchauhan1449 well, i didn’t exactly fix it, I mess around with gravity, but I just had to download the scripts, which was not what I hoped for but as i have hardly any C# knowledge and didn’t know how to fix it, i just downloaded them:(
@@chairchairyes2524 what is ur gravity
@@hustler__mindset i forgot and my laptop broke so i cant look
@@chairchairyes2524 I just switched to raytracing its so much better
it trys shooting then out of no where it pops up display 1 no cameras rendering
tomorrow i gona make tutorial for the gunshot and enemy subscribe to see it.
@ollgamgaming Today i gona publish one video for player and a simple map.
this is actually good and easy but one question when the projectile hits the ground then the ground disappears. which is bad for some type of games like fps shooters and others. is there is a way to get over this
yes, after OnCollisionEnter you need to put another "if" in the function (this one is an example, but there are a lot of ways to do this). In that if you need to put if (collision.gameObject.CompareTag("Enemy")) and then leave the two destroy function inside of this.
Now, in the inspector, you need to assign the tag ("Enemy") to an object, so the system recognise that when the bullet hit that object, before destroying it checks if it's an Enemy.
Sorry for my english, hope this helps.

My whole gun dissappears after I shoot once , can you help me?
dont put the BulletSpawnPosition in the gun put it in the gun tip so it doesnt spawn in the gun and destroy it
@@doublebigmackc I did put it in the tip but il try moving it a bit more forward
@@FuS1oNDaBest yeah but dont put it in the gun hitbox or collider
what if the script method is changed to a button?
while moving character, if i press left key and forward key at same time, then space doesnt work

how do i make the bullets dissapear if they hit something im tring to make a death whit a ragdoll and i want the bullet to destroy if they hit the enemy pls help

i got an error InvalidOperationException: You are trying to read Input using the UnityEngine.Input class, but you have switched active Input handling to Input System package in Player Settings.

How did the bullet destroy itself?
thank you so so much for this i kept getting compiler errors
for some reason my bullet doesnt move when spawned
nvm i fixed it by adjusting the rigidbody a bit
Yo can I get some help? the bullet shoots but it keeps going to the side
Try rotating the gun until u get the angle where it shoots forward
Or add a different part , make it small, call it Gun and put it inside the previous gun itself , and rotate it until it shoots forward
@@Chair-ig I just had to rotate the bullet thx tho
bullet dont destroy obstacles

how to make a shoot cooldown?
how can you call urself Unity3D School and u just dont explain and just let us copying it
Thanks bro
The bullet is too small, how can I solve this?
resize in prefab editor
thx
why my code is not working even if i copied your code
I'm looking for the answer to
that beat go hard!!!!!!!!!!!!!
🔥🔥
my gun breaks the ground when I shoot, can you tell me how to fix that? thank you.
you need to change the tag
@@imreallynotfunny4423 wdym
thx alot bro
i can't use ur script it says the associated scrpit can not be loaded pls help
This happens when there is compiler error in script. Recheck the script mentioned in the error message.
how do i make so when a bullet hits the ground it doesnt delete it?
use tags/layers
@@shlomohalev8122 Can you explain more? Am I supposed to change the script? If so what lines and what do I change them to?
@@adikh223 you can mark the ground with ground tag and then when the bullets hits the somthing destroy the bullet only if the bullet not collide with this ground tag
if you ever figured this out please tell me how
@@SirHotDogManTheFirst Put the bullet and the objects on the same layer
thank you 😁😁😁😁 you help if it dont work. click space
is there a way i can make it left click instead of space bar
tomorrow i gona make tutorial for the gunshot and enemy subscribe to see it.
Input.GetMouseButtonDown(0) means get LMB
@@bbproductions8975 1 for rmb right?
@@doublebigmackc yes and 2 for middle mouse button (scroll)
@@ALFAA06 nope 2 is for lmb and 3 is for scroll
Yo can you help the bullets won’t appear
Me too ~ I'm stuck on this part , my bullet doesn't show
for me it doesent work
ok now i realised that it was the key space to shoot, nice tutorial
hi thanks a lot!😁 but how can i shot with the gun?
use spacebar
Great vid worked fine but when I restarted Unity bullets/balls fell to the ground and didn't go anywhere else, anyone know how to fix it?
tomorrow i gona make tutorial for the gunshot and enemy subscribe to see it.
you just need to set the rigidbody of the bullet on no gravity
@@shalev2323x hi thanks for helping but it fixed its self after i restarted unity again thank and merry christmas

how to make it to mouse
use this code for the left mouse button
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Gun : MonoBehaviour
{
public Transform bulletSpawnPoint;
public GameObject bulletPrefab;
public float bulletSpeed = 10;
private void Update()
{
if (Input.GetKeyDown(KeyCode.Mouse0))
{
var bullet = Instantiate(bulletPrefab, bulletSpawnPoint.position, bulletSpawnPoint.rotation);
bullet.GetComponent().velocity = bulletSpawnPoint.forward * bulletSpeed;
}
}
}
first of all, annoying background "music" and second those clicks are even more annoying. and too LOUD!!! other then that. there might be some useful "info" in it
maybe if you focus on the content more then you would find it less annoying
i personally didn't find it annoying at all because I was trying to implement this shooting for weeks and there was always some flaw and everytime I searched for answers there were 2 3 hours videos
which didn't even solve my problem and then I found this
Doesn't work
tomorrow i gona make tutorial for the gunshot and enemy subscribe to see it.
works on my machine
heres the code if you wanna use lmb:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Gun : MonoBehaviour
{
public Transform bulletSpawnPoint;
public GameObject bulletPrefab;
public float bulletSpeed = 10;
void Update()
{
if(Input.GetMouseButtonDown(0))
{
var bullet = Instantiate(bulletPrefab, bulletSpawnPoint.position, bulletSpawnPoint.rotation);
bullet.GetComponent().velocity = bulletSpawnPoint.forward * bulletSpeed;
}
}
}
