Help
error CS1061: 'FixedJoystick' does not contain a definition for 'InputVector' and no accessible extension method 'InputVector' accepting a first argument of type 'FixedJoystick' could be found (are you missing a using directive or an assembly reference?)

FixedJoystick has Direction.

--Level.cs

void Update(){
//...
        var player = fps.GetComponent<PlayerMovement>();
        player.RunAxis = FixedJoistick.Direction;
//...
}
//...

--PlayerMovement.cs

public CharacterController controller;
..

public Vector2 RunAxis;
...
        void Update(){
        //...
        float x = RunAxis.x; 
        float z = RunAxis.y;

        Vector3 move = transform.right * x + transform.forward * z;
        controller.Move(move*speed*Time.deltaTime);

        velocity.y += gravity * Time.deltaTime;
        controller.Move(velocity * Time.deltaTime);   
//... 
}

Hope it will help.

Can please tell me in which componet this both file is put or tell can i create this two file
