Rotation Offset

Question

Hi

I have a simple game im playing around with. What I currently have is a fps controller which I have removed everything but the "mouse look" script, the main camera(player) is looking down a shooting range, on each side of that I am going to have a turret also point down the range.

What I want the turret(s) todo is to point relative to where the player is looking(FIG 1), I can make the turrets inherit the camera rotation but when I try to ajust that rotation based on the angle from the main camera i cant seem to get it to work. The turret just flips around on its axis and sticks no longer follwing any input(FIG 2).

Thanks

Try making a raycast out of your player's view, then use LookAt in the turrets with the coordinates of the raycast hit point.

Is there a way to make the turret look at a little smoother? For example if I have something in the foreground and look at something far away it will instantly snap to that point.

I was going to make turret rotation speed upgradeable

var target : GameObject;

function Update () {

 var fwd = transform.TransformDirection(Vector3.forward);

 var hit : RaycastHit;

 Debug.DrawRay(transform.position, fwd * 50, Color.green);



 if(Physics.Raycast(transform.position, fwd, hit, 50)){

     target.transform.LookAt(hit.point);

     Debug.Log(hit.point);

 }

}

Do you want the turrets to LookAt the target? Or look in the same direction as the camera. Fig 2 is the latter, they all look down the range, straight down. If you want the turrets to look at the target, use transform.LookAt(target). If you want them to look a some point down range, you need to know how far down range that is.

I want them to point where the player looks. So if the player looks at a target the turrets need to rotate to point at that target. Since they are not at the position of the player, they are either side of the player, they need to correct their own rotation based on the distance from the player, but I'm not sure on the best way to code this.

Fig 2 is showing how I have it currently, its basicly just inheriting the rotaion of the camera(player). But I don't want it this way because the turrets will never actualy shoot where I am ai$$anonymous$$g. I tried to add an offset but I just got some strange results.

Also the rotation of the turret model is different from the world rotation and that was causing me some headaches aswel. I put the object in an empty and the script onto that which seemed to fix it, but I still can not get it to rotate to where the player looks.
