Raycast only works once
I've been doing some test with raycasts and find this problem.
I've got a cube with a script that launch a raycast and when it interact with (for example) an sphere, the cube rotate to right and the direction of the ray do the same. That's not the problem. The problem appears when i move the sphere to make it interact with the new ray. Doing this, the cube should rotate and the direction of the new ray should do the same... but they doesn't!! I don't know what is wrong so please, help!
This is the script
public class rayoScript : MonoBehaviour {
Vector3 vector = Vector3.forward;
float distance = 2.0f;
// Update is called once per frame
void Update () {
RaycastHit hit;
Ray ray = new Ray(transform.position,vector * distance);
Debug.DrawRay(transform.position,vector * distance);
if(Physics.Raycast(ray,out hit,distance)){
transform.Rotate(new Vector3(0,90,0));
vector = Vector3.right;
}
Debug.Log(vector.x+"****"+vector.y+"****"+vector.z);
}
}

Vector3.forward is always towards positive 'Z' in world space. Likewise Vector3.Right is always towards the world positive 'X'. These vectors don't change just because you've rotated the cube. So you get one change when you go from using Vector3.forward to Vector3.right, but after that, your code always uses Vector3.right. If I understand correctly what you are trying to do, then I'd always cast my ray to 'transform.forward'. 'transform.forward' is the forward direction of the cube in world space (i.e. it changes as the cube is rotated). Using this variable will cast out from the front of the cube no matter which way it is facing. What that change, you don't need your vector variable at all.
Aaaaajam... seems logic jajaja XDD thanks for the advice men ^^ it works perfectly
