Question by Bormeth · Apr 05, 2011 at 07:08 PM · physicsraycastvector

RayCast problem :)

Trying to do something like

int layerID = LayerMask.NameToLayer("Platform"); if (!Physics.Raycast(transform.position, -Vector3.up, 0.8f) || !Physics.Raycast(transform.position, Vector3.forward, 0.8f, layerID)) { switch (state) { case State.Left: state = State.Right; break; case State.Right: state = State.Left; break; } }

     if (state == State.Right)
     {
         transform.Translate(Vector3.right * amtToMove);
     }
     else if (state == State.Left)
     {
         transform.Translate(Vector3.left * amtToMove);

     }

Aint working that well sadely, enemies or just freezing or looks like switching State on every FPS..

I don't really get what this script should do, but i guess that your (strange) condition with the two Raycasts will not turn false next frame if it's true. So it will toggle each frame until both raycasts hit something.


btw, just a small hint:
according to the boolean algebra:

(not R1) or (not R2) == not(R1 and R2)

The script sends raycast out to check if there is something under it or infront of it, then changes direction :)

Its an enemy in 2D ;) Mario Look alike approche.
