2d collision (563447)

Unity Engine

using UnityEngine;
using System.Collections;

public class Spawn_collision : MonoBehaviour{
    public void OnCollisionEnter2D( Collision2D col){
        if (col.gameObject.name == "item1") {
            Debug.Log ("starting collision");
                        //add points for item1
                } else if (col.gameObject.name == "item2") {
                        //add points for item2
                } else if (col.gameObject.name == "item3") {
                        //add points for item3
                } else if (col.gameObject.name == "name4") {
                        //add points for item4
                }
    }
}

i am using the above code to try detect 3 different items colliding with another 2d sprite, they are all 2d sprites yet they do not seem to collide. I have tried calling the class from start and making a overflow method and it just ran the overflow method and not this one. I need some help on how to call this method from the start method or on a different way to do this.
Also will, col.GameObject.name even work with a sprite

So, the event doesnt “trigger”?
They all got a BoxCollider or some other collider?
Do they all have a rigidbody2D?

3

yes they all have a boxcollider2d and rigidbody2d sorry forgot to mention that

4

Can you maybe post a screenshot?
Is the “OnCollisionEnter2D” even called?
Try debugging to check please.

5

what would you like a screen shot off and i have tried a debug.log in it and it never got printed but when i try call the method it goes on about an overflow method and when i create an overflow method it just runs that method

6

I’d just like to see the scene and one of those instances focused in the inspector…they r all the same, right?
So, the OnCollisionEnter2D is not triggered? …something must be wrong with the gameObject setup then. Screenshot would help. The objects are not kinematic, are they?

7

no they are not kinematic and yes they are all the same here is a ss of what i think you want Screenshot - c968bfb32b5cb172f27443f1d02d5d22 - Gyazo

The BoxCollider is set to Trigger…

Try using the OnTriggerEnter2D Method.

ok, i tried that and it still does not work, i am going to try creating an overflow method then calling it from start again

public class Spawn_collision : MonoBehaviour
{
    public void Start(){
        OnTriggerEnter2D ();
        }
    public Object OnTriggerEnter2D (Collider2D col)
    {
            Debug.Log ("starting collision");
                if (col.gameObject.name == "item1") {
            Debug.Log("col");
                } else if (col.gameObject.name == "item2") {
            Debug.Log("col");
                } else if (col.gameObject.name == "item3") {
            Debug.Log("col");
                } else if (col.gameObject.name == "name4") {
            Debug.Log("col");
                }
        return col;
    }
    public Object OnTriggerEnter2D (){
        string a = "1";
        return col;
    }
}

i have tried this overflow method and it is just going to the overflow method and not going to the method.
