@Override protected void updateStick() {
    if (down) {
        // GamepadEmulator takes values on a scale [-1; 1] so convert our values
        float w = getWidth() / 3;
        float diffX = currentX - initialX;
        float diffY = currentY - initialY;

        float bias = 0.3f;

        if (Math.abs(diffX) > Math.abs(diffY)) {
            diffY = Math.signum(diffY) * (Math.max(0, Math.abs(diffY) - bias * Math.abs(diffX)));
        } else {
            diffX = Math.signum(diffX) * (Math.max(0, Math.abs(diffX) - bias * Math.abs(diffY)));
        }

        float dx = MathUtils.clamp(diffX / w + 0.2f * Math.signum(diffX), -1, 1);
        float dy = MathUtils.clamp(diffY / w + 0.2f * Math.signum(diffY), -1, 1);
        GamepadEmulator.updateStick(stickId, dx, dy);
    } else {
        GamepadEmulator.updateStick(stickId, 0, 0);
    }
