Simple moving Cam in direction its facing

Questions & Answers
1

I need to move my cam in the direction its faceing.
It should be simple I don`t need velocity, speed etc.

I imagine somthing like this:

if(Input.GetKey(“w”)){
moveDirection=transform.forward;
}

if(Input.GetKey(“s”)){
moveDirection=transform.forward*-1;
}

var moveSpeed : float = 20.0;
function Update(){
if(Input.GetKey(KeyCode.W)){
transform.localPosition.z += moveSpeed * Time.deltaTime;
}
if(Input.GetKey(KeyCode.S)){
transform.localPosition.z -= moveSpeed * Time.deltaTime;
}
}

The Previous answer does not account for the camera’s pitch (rotation around the x vector) which is common in games (top down camera, free rotate camera, over-the-shoulder third person camera, etc). In order to account for this, use the following code.

 private void Update()
    {
        Vector3 movement = Vector3.zero;
        Vector3 camEuler = Camera.rotation.eulerAngles;
        camEuler.x = 0f;
        Quaternion normalizedRotation = Quaternion.Euler(camEuler);

        if (Input.GetKey(KeyCode.W))
        {
            movement += normalizedRotation * Vector3.forward;
        }

        if (Input.GetKey(KeyCode.S))
        {
            movement -= normalizedRotation * Vector3.forward;
        }

        if (Input.GetKey(KeyCode.A))
        {
            movement -= normalizedRotation * Vector3.right;
        }

        if (Input.GetKey(KeyCode.D))
        {
            movement += normalizedRotation * Vector3.right;
        }

        if (movement.magnitude > 1f)
        {
            movement = movement.normalized;
        }

        _charController.Move(movement * WalkSpeed * Time.deltaTime);
    }

This snippet removes the pitch from the camera’s current rotation (zeroing out the x portion of the camera’s euler angle), making it level with the world. To transform this into a usable movement vector, multiply the resulting rotation (normalizedRotation) by whichever direction you want to move the object.
