Mouse position help
Hi all. I'm trying to get a beam to go from an flying ship to the ground where the mouse is clicking. However I'm having a hard time getting the beam to go from the ship. Its a top down view so the camera is not attached to the ship so I have a problem with doing raycasts from the point of view of the ship. heres what I've been using
if(Input.GetMouseButtonDown(0)){
var mousePo = camera.ScreenToWorldPoint (Vector3 (Input.mousePosition.x, Input.mousePosition.y,camera.nearClipPlane));
var ray = camera.ScreenPointToRay(mousePo);
Instantiate (particle, mousePo, Quaternion.identity);
}
any idea how I can make a beam go from the ship down to the ground where the mouse is clicking? Thanks in advance!
I believe your solution is better considered in two parts:
1- raycast from camera to ground
2- ray from any transform to raycast hitpoint
in particular, to solve the first need:
private Plane drivingplane = new Plane(Vector3.up, Vector3.zero);...
void Update () {
Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
float ent = 1.0f;
if (drivingplane.Raycast(ray,out ent))
{
Vector3 hitPoint = ray.GetPoint(ent);
Debug.DrawRay (ray.origin, ray.direction * ent, Color.green);
}
else
Debug.DrawRay (ray.origin, ray.direction * 10, Color.red);
}
consequently, to solve point 2
Debug.DrawRay (transform.position, hitpoint);
