VRStageParameters.sizeY

Deprecated

This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

The sizeY read-only property of the VRStageParameters interface returns the depth of the play-area bounds in meters.

Note: This property was part of the old WebVR API. It has been superseded by the WebXR Device API.

The bounds are defined as an axis-aligned rectangle on the floor, for safety purposes. Content should not require the user to move beyond these bounds; however, it is possible for the user to ignore the bounds resulting in position values outside of this rectangle. The center of the rectangle is at (0,0,0) in standing-space coordinates.

Syntax

var mySizeY = vrStageParametersInstance.sizeY;

Value

A float representing the depth in meters.

Examples

var info = document.querySelector('p');
var vrDisplay;

navigator.getVRDisplays().then(function(displays) {
  vrDisplay = displays[0];
  var stageParams = vrDisplay.stageParameters;
  // stageParams is a VRStageParameters object

  if(stageParams === null) {
    info.textContent = 'Your VR Hardware does not support room-scale experiences.'
  } else {
    info.innerHTML = '<strong>Display stage parameters</strong>'
                 + '<br>Sitting to standing transform: ' + stageParams.sittingToStandingTransform
                 + '<br>Play area width (m): ' + stageParams.sizeX
                 + '<br>Play area depth (m): ' + stageParams.sizeY
  }
});

Specifications

This property was part of the old WebVR API that has been superseded by the WebXR Device API. It is no longer on track to becoming a standard.

Until all browsers have implemented the new WebXR APIs, it is recommended to rely on frameworks, like A-Frame, Babylon.js, or Three.js, or a polyfill, to develop WebXR applications that will work across all browsers [1].
