Get Started

ViroSceneNavigator

DEPRECATED (starting in ViroReact 2.5.0)

<ViroSceneNavigator> has been DEPRECATED. Please use one of the following:

  1. ViroVRSceneNavigator for VR applications.
  2. ViroARSceneNavigator for AR applications.
  3. Viro3DSceneNavigator for 3D (non AR/VR) applications.

A ViroSceneNavigator component is the entry point for VR applications. Please see our Scene Navigation Guide for more information on how to properly navigate between scenes.

Example use:
var MyStartScene = require('./MyStartScene');

import {
  AppRegistry,
  ViroScene,
  ViroSceneNavigator,
} from 'react-viro';

var ViroSceneNav = React.createClass({
  render: function() {
    return (
      <ViroSceneNavigator
        initialScene={{
          scene: MyStartScene,
        }}
      />
    );
  }
})

Methods

These are the functions available on the ViroSceneNavigator component, you can get the handle to the ViroSceneNavigator in 2 ways:

  1. using the built-in React Native ref property to grab a reference
  2. from your ViroScene which has been added to the ViroSceneNavigator, it will be given the reference to the ViroSceneNavigator in this variable: this.props.sceneNavigator.
push(scene: ViroScene)

Push the given scene onto scene stack, displaying the scene to the user.

Parameters Description
scene Scene that will be pushed onto the stack and displayed to the user
pop()

Pop the top most scene of the stack, effectively going back to the previous scene.

pop(n: number)

Go back n scenes at once. If n is equal to 1 this is equivalent to calling pop().

jump(scene: ViroScene)

Move to the given scene in the stack, removing it from its current position in the stack and placing it on top, thereby displaying it to the user. If the scene is not already on the stack, this method pushes the scene to the top of the stack, displaying it to the user. This is best used in applications where the user jumps between a set of scenes frequently.

Parameters Description
scene Scene that will be moved or pushed to the top of the stack and displayed to the user
replace(scene: ViroScene)

Replace the currently displayed scene (the scene at the top of the stack) with the given scene, displaying it to the user. This leaves the remainder of the stack unchanged.

Parameters Description
scene Scene that will replace the scene at the top of stack and be displayed to the user
recenterTracking()

Reorients the virtual world such that directly forward of the user is [0, 0, -1] by rotating the scene by the user's y-rotation.
