Well, i'm trying to make a simple Collision Side detection with raycast based on [this example][1]
[1]: http://www.facebook.com/l.php?u=http%3A%2F%2Fanswers.unity3d.com%2Fquestions%2F339532%2Fhow-can-i-detect-which-side-of-a-box-i-collided-wi.html&h=vAQFewUIW
But i'm getting a NullReferenceException at this line:
normal = rcashit.transform.TransformDirection(normal);
Code:
if (col.gameObject.tag == "Player") {
Ray obray = new Ray(col.gameObject.transform.position, (col.gameObject.transform.position - transform.position).normalized);
RaycastHit rcashit;
Physics.Raycast(obray, out rcashit);
Vector3 normal = rcashit.normal;
normal = rcashit.transform.TransformDirection(normal);
if (normal == rcashit.transform.right) {
t += 1;
if (t >= 30) {
PlayerController p = target.GetComponent();
p.health -= 1;
t = 0;
}
}
}
Can please someone help me? Thanks!
