![]() Null is also returned if the transformation from local to Scene is not invertible. When you trap events on the window, document, or other roomy elements, you can get the coordinates of that event (e.g. ![]() The method screenToLocal() returns local Node's coordinates of the point or null if Node is not in a Window. Working Draft: No change from Document Object Model (DOM) Level 2 Events Specification. Document Object Model (DOM) Level 3 Events Specification The definition of MouseEvent.screenX in that specification. Working Draft: Redefines MouseEvent from long to double. * Checks if a shape is within highlight range of a point on the screen. double screenX - x coordinate of a point on a Screen double screenY - y coordinate of a point on a Screen Return. The definition of screenX in that specification.

The screenX read-only property of the MouseEvent interface provides the horizontal coordinate (offset) of the mouse pointer in global (screen) coordinates. isoY 2screenY / tileH - screenX / tileW - isoY 2isoY 2screenY / tileH - screenX / tileW isoY screenY / tileH - screenX / (2tileW) Solving linear equations comes very much in handy for a lot of programming, especially graphics or game related programming.
