5. This is a very nice funcion that will allow us to debug our game, the result of which
we won't see in the real game. Let's add the following block of code:
public function OnDrawGizmos() : void {
mesh = GetComponent(MeshFilter).sharedMesh;
f_height = mesh.bounds.size.y* transform.localScale.y;
var v3_right : Vector3 = new Vector3(transform.position.x +
(collider.bounds.size.x*0.45), transform.position.y, transform.
position.z);
var v3_left : Vector3 = new Vector3(transform.position.x -
(collider.bounds.size.x*0.45), transform.position.y, transform.
position.z);
Gizmos.color = Color.red;
Gizmos.DrawRay(transform.position, transform.TransformDirection
(-Vector3.up) * (f_height * 0.5));
Gizmos.DrawRay(v3_right, transform.TransformDirection (-Vector3.
up) * (f_height * 0.5));
