Ignoring collisions

I want to ignore the collisions between the enemies created by "inamici" and points created by"puncte2" .
This is my script :
if (Time.time>init+0.5)
{

transform.position = new Vector3(transform.position.x, Random.Range(-5, 5), transform.position.z);
Instantiate(inamici, transform.position, transform.rotation);
init = Time.time;

}
if (Time.time > init2 + 0.1)
{
transform.position = new Vector3(transform.position.x, Random.Range(-5, 5), transform.position.z);
Instantiate(point2, transform.position, transform.rotation);
init2 = Time.time;
}
Physics2D.IgnoreCollision(point2.GetComponent<Collider2D>(), inamici.GetComponent<Collider2D>());



The problem is that ONLY THE FIRST COLLISION IS IGNORED.The rest of the object created are colliding as usual.Some tips ?

 

GetComponent<Collider2D>()?

so GetComponent<BoxCollider2D>(); xd

 

It doesnt work either.

 

Set "inamici" and "point2" to different layers and edit the Layer Collision Matrix to make the two layers don't collide.

 

It sort of looks like you're referencing prefabs in your IgnoreCollision() call. I'm not sure, because I can't see where inamici and point2 are initialized, but try using

Code (CSharp):

1. GameObject inm = Instantiate(inamici, transform.position, transform.rotation);     //Replace your first Instantiate() call with this
2.  
3. ...
4.  
5. GameObject p2 = Instantiate(point2, transform.position, transform.rotation);     //Replace your second instantiate call with this
6.  
7. ...
8.  
9. Physics2D.IgnoreCollision(p2.GetComponent<Collider2D>(), inm.GetComponent<Collider2D>());     //Replace your IgnoreCollision() call with this

Instantiate() returns a reference to the created instance, so you need use that reference to specifically ignore collisions with each instance as you create them.

Also, in the future be sure to use code tags when you post code. http://forum.unity3d.com/threads/using-code-tags-properly.143875/ It allows us to see which language you're using easily as well as reference line numbers, not to mention the color coding.

 

Use different layers and uncheck this layers in the Physics2D matrix
