Rotating map and camera

so I’m currently making a isometric game, and have just gotten rotating the world to work.

This is what I use to rotate the world tiles.


    public int getDrawX(){
        double rad = Math.toRadians(Screen.rotateScreen);
        double rotX = (Math.cos(rad) * x) - (Math.sin(rad) * y);
        double rotY = (Math.sin(rad) * x) + (Math.cos(rad) * y);
        
        return (int)((rotY * WIDTH / 2) + (rotX * WIDTH / 2));
    }
    
    public int getDrawY(){
        double rad = Math.toRadians(Screen.rotateScreen);
        double rotX = Math.cos(rad)*x - Math.sin(rad)*y;
        double rotY = Math.sin(rad)*x + Math.cos(rad)*y;
        
        return (int)((rotX * HEIGHT / 2) - (rotY * HEIGHT / 2) - height);
    }

and this is what I use to rotate the screen


        if(e.getKeyCode() == KeyEvent.VK_R){
            Screen.rotateScreen = 90+Screen.rotateScreen%360; 
            
            double rad = Math.toRadians(Screen.rotateScreen);
            double newScreenX = Math.cos(rad)*Screen.offsetX - Math.sin(rad)*Screen.offsetY;
            double newScreenY = Math.sin(rad)*Screen.offsetX + Math.cos(rad)*Screen.offsetY;
            
            Screen.offsetX = (int)newScreenX;
            Screen.offsetY = (int)newScreenY;
        }

The world rotate just fine, but the screen doesn’t follow the rotation.
