Getting positions on your screen

[jelknab]

Hi,

 

I'd like to share my way of getting a Position on your screen to make something like this:

 

 

The cool thing is these lines rotate with your camera.

 

    public static Point getPositionOnScreen(Script script, Position middle /* myPosition = default */, Position targetPosition) {
        final Point drawAt = new Point(642, 83); // Default miniMap centre 642, 83
        final double zoom = 0.25; // Default: 0.25
        
        // Getting a direction.
        int x = middle.getX() - targetPosition.getX();
        int y = middle.getY() - targetPosition.getY();

        // Getting the correct angle.
        double angle = (Math.toDegrees(Math.atan2(y, x)) - script.client.getCameraYawAngle() - 90) * Math.PI / 180;

        // Getting the position on the screen.
        x = (int) StrictMath.round(StrictMath.sin(angle) * (middle.distance(targetPosition) / zoom));
        y = (int) StrictMath.round(StrictMath.cos(angle) * (middle.distance(targetPosition) / zoom));

        return new Point(drawAt.x + x, drawAt.y + y);
    }

 

Credits would be kind.

Enjoy.
