Gamepad.displayId - Web APIs 编辑

Experimental

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The displayId read-only property of the Gamepad interface returns the VRDisplay.displayId of the associated VRDisplay — the VRDisplay that the gamepad is controlling the displayed scene of.

A Gamepad is considered to be associated with a VRDisplay if it reports a pose that is in the same space as the VRDisplay.pose.

Syntax

var myDisplayId = gamepadInstance.displayId;

Value

A number representing the associated VRDisplay.displayId. If the number is 0, then the gamepad is not associated with a VR display.

Examples

window.addEventListener("gamepadconnected", function(e) {
  if(!e.gamepad.displayId) {
    console.log('Gamepad connected');
  } else {
    console.log('Gamepad connected, associated with VR display ' + e.gamepad.displayId);
  }
});
