or vice versa (when the vrdisplaypresentchange
event fires).
The event object is of type VRDisplayEvent
.
Syntax
window.onvrdisplaypresentchange = functionRef;
Examples
The presenting state of a VRDisplay
can be checked using the
VRDisplay.isPresenting

if(vrDisplay.isPresenting) {
info.textContent = 'Display has started presenting.';
} else {
info.textContent = 'Display has stopped presenting.';
}
};
