Example 25 with Point2D

use of javafx.geometry.Point2D in project FXyzLib by Birdasaur.

the class CameraController method getMouseDelta.

private Point2D getMouseDelta(MouseEvent event) {
    Point2D res = new Point2D(event.getSceneX() - previousX, event.getSceneY() - previousY);
    previousX = event.getSceneX();
    previousY = event.getSceneY();
    return res;
}
