Collision Detection

Question

I'm trying to detect what object my character is colliding with. My simple block of code is always giving me "null" back.

 function OnCollisonEnter (theCollision : Collision)
 {
 
     /*if(theCollision.CompareTag == "Floor")
         {
                grounded = true;// Sets grounded variable to true.
             //Debug.Log(theCollision.tag); 
         }
     */
     
     print(theCollision);
     
 }

As you can see the end result would be to detect to tag and use that but it doesn't even seem to be dectecting what object it collides with. I'm using a rigidbody on cube $$anonymous$$tting another cube. I'm super new but any help would be greatly appreciated.

 private var objectCollided : string;

 function OnCollisionEnter(objectCollided : Collision)
 {
     //if(objectCollided.gameObject.tag == "BlaBla")
     //{
         //Do Somet$$anonymous$$ng
     //}
     //print(objectCollided.gameObject.tag);
     //Debug.Log(objectCollided.gameObject.tag);
 }
 
 function OnGUI()
 {
     GUILayout.Label(Rect(Screen.width/2, Screen.heigth/2,0,0), "Collided With "+objectCollided);
 }

"theCollision" stores collision data, not the actual object you collided with. As Coreyf716 said you need to use Debug.Log(theCollision.collider.tag); to get the tag of the object you collided with. Also, I t$$anonymous$$nk you're using CompareTag wrong. Try if(theCollision.collider.CompareTag("Floor")). Once again, you were trying to get the tag of the collision data, not the object you collided with. T$$anonymous$$s stuff can be a bit confusing if you're new. :) I t$$anonymous$$nk t$$anonymous$$s should work. Good luck!
