[Solved] 2D Collision Problems

I dont know if its because I use sprites, I want to make a prefab destroy itself when colliding with a sprite with tag "Barrier", they have Rigidbody2Ds, Box Collider 2Ds (with IsTrigger true) , same Z and they still dont collide. Can anybody identify what's wrong?

This is my code if it helps.

Code (CSharp):

1.     void OnCollisionEnter2D(Collision2D coll)
2.     {
3.         if (coll.gameObject.tag == "Barrier")
4.         {
5.             Destroy(gameObject);
6.         }
7.     }

 

check the tag (does the sprite really contain the tag, maybe spelling mistake). You could use Debug.Log("Test"); in OnCollisionEnter to check if there is a collision.

I'm also new to unity, but I hope this will help!

 

No, thats not the problem :c, but thanx

also the Debug.Log doesnt work, Ive tried, its not detecting the collision, may it be cause they are sprites?

 

Here is a screenshot of the Barrier's Components: http://prntscr.com/cfalet

And here one of the projectile's: http://prntscr.com/cfam1h

 

Here's the whole projectile code:

Code (CSharp):

1. public class ShootScript : MonoBehaviour
2. {
3.    
4.     public float MoveX;
5.     public float MoveY;
6.     public float MoveSpeed;
7.     Movement player;
8.  
9.     void Start()
10.     {
11.         player = GameObject.FindWithTag("Player").GetComponent<Movement>();
12.         MoveX = player.FacingDirectionX;
13.         MoveY = player.FacingDirectionY;
14.     }
15.  
16.     void Update()
17.     {
18.         GetComponent<Rigidbody2D>().velocity = new Vector2(MoveX * MoveSpeed, MoveY * MoveSpeed);
19.     }
20.     void OnCollisionEnter2D(Collision2D coll)
21.     {
22.         if (coll.gameObject.tag == "Barrier")
23.         {
24.             Destroy(gameObject);
25.         }
26.     }
27. }

 

There is no collision because both colliders are set as triggers. Try using OnTriggerEnter2D() instead-- you'll have to change coll from a Collision to a Collider.

 

So only the barrier should have IsTrigger and the could should be like this?

Code (CSharp):

1.  
2.     void OnTriggerEnter2D(Collider2D coll)
3.     {
4.         if (coll.gameObject.tag == "Barrier")
5.         {
6.             Destroy(gameObject);
7.         }
8.     }

 

yay its solved thanks so much guys
