transform.InverseTransformPoint

[Griffo]

Hi, I’m trying to find what side of the object my projectile collides with, can someone please tell me where I’m going wrong, this is what I thought would tell me, thanks.

function OnCollisionEnter(collision : Collision) {

var contact : ContactPoint = collision.contacts[0];

var relativePosition = transform.InverseTransformPoint(contact);

	if(relativePosition.x > 0){
		print ("The object is to the right");
	}else{
		print ("The object is to the left");
	}

	if (relativePosition.y > 0) {
		print ("The object is above");
	}else{
		print ("The object is below");
	}

	if (relativePosition.z > 0) {
		print ("The object is in front");
	}else{
		print ("The object is behind");
	}
}

You could use the cross product to define where it is:

void OnCollisionEnter(Collision other) {
    Vector3 direction = other.contacts[0].point - transform.position;
    var cross = Vector3.Cross(transform.forward, direction);
    if (cross.y < 0) print ("Left");
		else print("right");
}

function OnCollisionEnter(other:Collision){
    var direction:Vector3 = other.contacts[0].point - transform.position;
    var cross :Vector3 = Vector3.Cross(transform.forward, direction);
    if (cross.y < 0) print ("Left");
		else print("right");
}
