So im trying to have a spotlight move around the player in a fixed manner with a 3rd person perspective. The Spotlight moves to follow where the mouse is relative to its fixed rotation point around the player. On top of it the spot light is constantly pointing outwards and should never face the player. Lastly Im hoping to be able to make the spotlight look up or down if necessary, also be able to move the spotlight up or down if possible. I have simple version that does everything but the adjustments to the look direction and the start height of the spotlight, so i think im doing something wrong. Any help is greatly appreciated, Thanks in advance.
public void lightMouseMovement()
{
float distToLight;
float distToLookAt;
Plane playerPlane;
float rayDist = 0f;
//Distance from Player to Light Object
distToLight = (player.transform.position - this.transform.position).magnitude;
//Distance from Player to Light Look At Object
distToLookAt = (player.transform.position - lookAtObject.transform.position).magnitude;
playerPlane = new Plane(Vector3.up, player.transform.position);
//Creates ray from Screen to Point
Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
//Sets rayDist to distance from Camera to movementPlane OR cancels out(parallel or opposite direction)
if (playerPlane.Raycast(ray, out rayDist))
{
//Get Collision Point in world space
Vector3 point = ray.GetPoint(rayDist);
//Move to new Rotational Posistion
this.transform.position = player.transform.position + (point - player.transform.position).normalized * distToLight;
}
if (playerPlane.Raycast(ray, out rayDist))
{
//Get Collision Point in world space
Vector3 point = ray.GetPoint(rayDist);
//Move to new Rotational Posistion
lookAtObject.transform.position = player.transform.position + (point - player.transform.position).normalized * distToLookAt;
}
//Make Height Adjustment to new point
this.transform.position = new Vector3(this.transform.position.x, this.transform.position.y + lightYAdj, this.transform.position.z);
lookAtObject.transform.position = new Vector3(lookAtObject.transform.position.x, lookAtObject.transform.position.y + lookAtYAdj, lookAtObject.transform.position.z);
//Turn Light to Look at Look At Object
this.transform.LookAt (lookAtObject.transform.position);
