Player move and camera problem

Question

Hi everyone, I've started to use Unity3D one week ago... I've done a lot of trials before ask this... I've change code a lot of times... I've been able to solve some errors... But i didn't understand where is this bug... It works fine at start but when you move some mouse and keyboard, it gives some problems... This JavaScript have to be applicated to a Player (Capsule) with behind a Main Camera (used this to semplify work)... So if someone can help me, A lot of thanks!!!

Code:

 private var direction : Vector3; // Direction of player to know next position
  
 function Update () {
     Camera.main.transform.LookAt(transform); // Normal LookAt function
     direction = Camera.main.transform.forward; // I've set the direction of player like camera's one.
    
     transform.Translate(direction * Input.GetAxis("Vertical"),Space.World); // Up/Down move player near/further than camera
     transform.Translate(direction.z * Input.GetAxis("Horizontal"),0,direction.x * -Input.GetAxis("Horizontal"),Space.World); // Horizontal Movement
  
     var mouX : float = Input.GetAxis("Mouse X");
     var mouY : float = Input.GetAxis("Mouse Y");
    
     transform.RotateAround(transform.position,Vector3.up,mouX); // Move Player and camera horizontally by mouse
     var euler = Camera.main.transform.eulerAngles.x; // See camera's rotation to put a limit
     if(euler < 180){
         if((euler < 50) || (mouY > 0)) // I don't want a lot of vertical vision
             Camera.main.transform.RotateAround(transform.position,Vector3.right,-mouY); // To look Around
     }else{
         if((euler > 330) || (mouY < 0))
             Camera.main.transform.RotateAround(transform.position,Vector3.right,-mouY);  
     }
    
     Screen.lockCursor = true; // Normal Cursor locked function
 }

Vector3.right will always rotate around the world X axis. Once you rotate your character around Y, this is no longer what you want.

So instead, rotate around the local X axis of your character:

 Camera.main.transform.RotateAround(transform.position,transform.right,-mouY);

Note on the other hand, the use of Vector3.up is generally fine, since you usually still want to rotate around world Y instead of local Y, even if your character is facing up or down.

Please post this as a new, separate question. It is unrelated to this question, and will also not be seen here (except by the two people subscribed to this question...).
