Question by ThomasQ · Apr 07, 2011 at 01:20 AM · gameobjecttagoncollisionenter

How to check what is getting hit with OnCollisionEnter

Hi!

I use this script to spwan ragdolls & explosions etc.. It's very basic, and it gives me a lot of headache.. How do I check with witch gameobject it collides, and what's the correct way to use that in an If, Then, Else statement? I'm new to Unity And Java, so please help a n00b out! :D

var explosion : Transform;

function OnCollisionEnter( collision : Collision) { if (collision.relativeVelocity.magnitude > 4.5){ Destroy (gameObject); Debug.Log(collision.relativeVelocity.magnitude ); var theClonedExplosion : Transform; theClonedExplosion = Instantiate(explosion, transform.position, transform.rotation); }

}

Thanks in advance!!

Put in the OnCollisionEnter

print(collision.transform.gameObject);

Have fun =).

Oh, I didn't read all of your question, haha. Sorry. I seriously just went in Unity and tested it. But um, for an if/else statement... If you want to check what object hit it and act accordingly...

  if(collision.transform.gameObject == NAME_HERE)
  {
      //do stuff here
  } else {
      //Do stuff to any object here
  }

And also, if you'd like to test another case, do it as:

else if (collision.transofrm.gameObject == OTHER_NAME_HERE){
    //Do stuff here.
}
else if (collision.transofrm.gameObject == OTHER_NAME_HERE){
    //Do stuff here.
}

Sorry about the short answer... Was just going by your title and a quick scan... Haha.
