PointerEvent: tiltY property

The tiltY read-only property of the PointerEvent interface is the angle (in degrees) between the X-Z plane of the pointer and the screen. This property is typically only useful for a pen/stylus pointer type.

For an illustration of this property, see Figure 3 in the specification.

Value

The angle in degrees between the X-Z plane of the pointer (stylus) and the screen. The range of values is -90 to 90, inclusive, where a positive value is a tilt towards the user. For devices that do not support this property, the value is 0.

Examples

This example illustrates simple accessing of the tiltX and tiltY properties.

js

someElement.addEventListener(
  "pointerdown",
  (event) => {
    process_tilt(event.tiltX, event.tiltY);
  },
  false
);
