2D Collision

Questions & Answers

Hi!

I’m making a 2D game where you are a space ship dodging asteroids. The asteroids and space ship are just rectangles at the moment so i use BoxCollider2D for both of them. I tag the astroid as “Asteroid” and the player space ship as “Player”. I then make 2 scripts. The problem is that nothing happens when the two objects are supposed to collide.

PlayerCollision:
function Start () {

}

function Update () {

}

function OnCollisionEnter2D(coll: Collision2D){
   if(coll.gameObject.tag=="Asteroid"){
      Destroy(gameObject);
   }
}

AsteroidCollision:

function Start () {

}

function Update () {

}

function OnCollisionEnter2D(coll: Collision2D){
   if(coll.gameObject.tag=="Player"){
      Application.LoadLevel(Application.loadedLevel);
      Destroy(gameObject);
   }

Seems weird. I know this script of mine works, it’s in C# though. But feel free to test it.

void OnCollisionEnter2D(Collision2D coll) 
	{
		if (coll.gameObject.tag == "Player")
		{

				player.Die();

		}
		
	}

Also, I wouldn’t have an OnCollisionEnter on both my scripts. Keep it at one of them. But I might be wrong.

If you want it in only one script do like this on your AsteroidCollision:

private PlayerCollision player; //Or whatever scriptname u have



void OnCollisionEnter2D(Collision2D coll) 
    {
        if (coll.gameObject.tag == "Player")
        {
                player.Die();
        }

    }

void Start () {
	player = GameObject.Find("playerObjectName").GetComponent<PlayerCollision>();
	}
