converting 3th person camera

I need to converting 3th person camera to not require ThirdPersonController script and use my own controler i am using the 3th person camera script from the Standard Assets folder and it worked well until I removed character controller. I know the 3th person camera script depends on it but is there a way to change it to use this.

// Move object using accelerometer var speed = 10.0;

 function Update () {
     var dir : Vector3 = Vector3.zero;
 
     // we assume that device is held parallel to the ground
     // and Home button is in the right hand
     
     // remap device acceleration axis to game coordinates:
     //  1) XY plane of the device is mapped onto XZ plane
     //  2) rotated 90 degrees around Y axis
     dir.x = -Input.acceleration.y;
     dir.z = Input.acceleration.x;
     
     // clamp acceleration vector to unit sphere
     if (dir.sqrMagnitude > 1)
         dir.Normalize();
     
     // Make it move 10 meters per second instead of 10 meters per frame...
     dir *= Time.deltaTime;
         
     // Move object
     transform.Translate (dir * speed);
 }

also I get this notice "Please assign a target to the camera that has a ThirdPersonController script attached. UnityEngine.Debug:Log(Object) ThirdPersonCamera:Awake() (at Assets/Standard Assets/Character Controllers/Sources/Scripts/ThirdPersonCamera.js:58)"
