Raycast not working with tilted plane
Hello !
Here's my configuration : 
I'm am trying to evaluate the angle of the plane under the cube. It works when :
Both the cube and the plane are horizontally placed
The plane is horizontal and the cube is tilted
But not and here's my problem when :
-The cube is horizontal and the plane tilted
I don't understand why the raycasts hit show the same value whereas the plane is titled
Here's the code :
public class Raycast : MonoBehaviour
{
float d1, d2, D;
double alpha, beta;
void FixedUpdate()
{
RaycastHit hit;
Vector3 p1 = new Vector3(2.0f, 0, 0);
Vector3 p2 = new Vector3(-2.0f, 0, 0);
if (Physics.Raycast(p1, Vector3.up, out hit))
{
Debug.DrawRay(new Vector3(2.0f, 0, 0), Vector3.up, Color.green);
print("Found an object from p1- distance: " + hit.distance);
d1 = hit.distance;
}
if (Physics.Raycast(p2, Vector3.up, out hit))
{
Debug.DrawRay(new Vector3(-2.0f, 0,0), Vector3.up, Color.red);
print("Found an object from p2 - distance: " + hit.distance);
d2 = hit.distance;
}
D = Math.Abs(d2 - d1);
Debug.Log("D : " + D);
if (D != 0)
{
alpha = (Math.Atan(4 / D))* 180 / Math.PI; //conversion en degrés
Debug.Log("alpha : " + alpha);
beta = (90 - alpha);
Debug.Log("TILT ANGLE : " + beta);
}
else
{
beta = 0;
Debug.Log("beta : " + beta);
}
}
}
Thanks for your help
