Props

animation

TypeDescription
PropTypes.shape({ name: PropTypes.string, delay: PropTypes.number, loop: PropTypes.bool, onStart: PropTypes.func, onFinish: PropTypes.func, run: PropTypes.bool, })A collection of parameters that determine if this component should animate. For more information on animated components please see our Animation Guide.

dragPlane

TypeDescription
PropTypes.shape({ planePoint:PropTypes.arrayOf(PropTypes.number), planeNormal:PropTypes.arrayOf(PropTypes.number), maxDistance:PropTypes.number})When a drag type of "FixedToPlane" is given, dragging is limited to a user defined plane. The dragging behavior is then configured by this property (specified by a point on the plane and its normal vector). You can also limit the maximum distance the dragged object is allowed to travel away from the camera/controller (useful for situations where the user can drag an object towards infinity).

dragType

TypeDescription
PropTypes.oneOf(["FixedDistance", "FixedToWorld"])Determines the behavior of drag if onDrag is specified.|Value|Description||:------|:----------:||FixedDistance| Dragging is limited to a fixed radius around the user, dragged from the point at which the user has grabbed the geometry containing this draggable node||FixedDistanceOrigin| Dragging is limited to a fixed radius around the user, dragged from the point of this node's position in world space.||FixedToWorld| Dragging is based on intersection with real world objects. Available only in AR ||FixedToPlane| Dragging is limited to a fixed plane around the user. The configuration of this plane is defined by the dragPlane property.|The default value is "FixedDistance".

ignoreEventHandling

TypeDescription
PropTypes.boolWhen set to true, this control will ignore events and not prevent controls behind it from receiving event callbacks.The default value is false.

onClick

TypeDescription
PropTypes.funcCalled when an objeect has been clicked.Example code: _onClick(position, source) { // user has clicked the object}

onClickState

TypeDescription
PropTypes.funcCalled for each click state an object goes through as it is clicked. Supported click states and their values are the following:|State Value|Description||:------|:----------:||1| Click Down: Triggered when the user has performed a click down action while hovering on this control.||2| Click Up: Triggered when the user has performed a click up action while hovering on this control.||3| Clicked: Triggered when the user has performed both a click down and click up action on this control sequentially, thereby having "Clicked" the object.|Example code: _onClickState(stateValue, position, source) { if(stateValue == 1) { // Click Down } else if(stateValue == 2) { // Click Up } else if(stateValue == 3) { // Clicked }}For the mapping of sources to controller inputs, see the Events section.

onDrag

TypeDescription
PropTypes.funcCalled when the view is currently being dragged. The dragToPos parameter provides the current 3D location of the dragged object. Example code: _onDrag(dragToPos, source) { // dragtoPos[0]: x position // dragtoPos[1]: y position // dragtoPos[2]: z position} For the mapping of sources to controller inputs, see the Events section. Unsupported VR Platforms: Cardboard iOS

onFuse

TypeDescription
PropTypes.oneOfType PropTypes.oneOfType([ React.PropTypes.shape({ callback: React.PropTypes.func.isRequired, timeToFuse: PropTypes.number }), React.PropTypes.func,]) As shown above, onFuse takes one of the types - either a callback, or a dictionary with a callback and duration. It is called after the user hovers onto and remains hovered on the control for a certain duration of time, as indicated in timeToFuse that represents the duration of time in milliseconds. While hovering, the reticle will display a count down animation while fusing towards timeToFuse.Note that timeToFuse defaults to 2000ms.For example: _onFuse(source){ // User has hovered over object for timeToFuse milliseconds}For the mapping of sources to controller inputs, see the Events section.

onHover

TypeDescription
React.PropTypes.funcFunction to be invoked when the user hovers on or off the container view. If defined, this is only invoked if the child hovered upon doesn't have onHover defined. For instance, let's say you have a that contains a few buttons and text. If none of them have a onHover handler defined, and they get hovered upon, then this function will invoke, effectively capturing the onHover event from it's children.For example: _onHover(isHovering, position, source) { if(isHovering) { // user is hovering on the container view. } else { // user is no longer hovering on the container view. }}

onPinch

TypeDescription
React.PropTypes.funcCalled when the user performs a pinch gesture on the control. When the pinch starts, the scale factor is set to 1 is relative to the points of the two touch points. For example: _onPinch(pinchState, scaleFactor, source) { if(pinchState == 3) { // update scale of obj by multiplying by scaleFactor when pinch ends. return; } //set scale using native props to reflect pinch. }pinchState can be the following values:|State Value|Description||:------|:----------:||1| Pinch Start: Triggered when the user has started a pinch gesture.||2| Pinch Move: Triggered when the user has adjusted the pinch, moving both fingers. ||3| Pinch End: When the user has finishes the pinch gesture and released both touch points. |This event is only available in AR.

onPortalEnter

TypeDescription
PropTypes.funcCalled when the user enters into this ViroPortalScene through a ViroPortal.

onPortalExit

TypeDescription
PropTypes.funcCalled when the user exits this ViroPortalScene through any ViroPortal.

onRotate

TypeDescription
PropTypes.funcCalled when the user performs a rotation touch gesture on the control. Rotation factor is returned in degrees.When setting rotation, the rotation should be relative to it's current rotation, not set to the absolute value of the given rotationFactor.For example: _onRotate(rotateState, rotationFactor, source) { if (rotateState == 3) { //set to current rotation - rotationFactor. return; } //update rotation using setNativeProps },rotationFactor can be the following values:|State Value|Description||:------|:----------:||1| Rotation Start: Triggered when the user has started a rotation gesture.||2| Rotation Move: Triggered when the user has adjusted the rotation, moving both fingers. ||3| Rotation End: When the user has finishes the rotation gesture and released both touch points. |This event is only available in AR.

onScroll

TypeDescription
PropTypes.funcCalled when the user performs a scroll action, while hovering on the control.For example: _onScroll(scrollPos, source) { // scrollPos[0]: x scroll position from 0.0 to 1.0. // scrollPos[1]: y scroll position from 0.0 to 1.0.}For the mapping of sources to controller inputs, see the Events section.Unsupported VR Platforms: Cardboard(Android and iOS)

onSwipe

TypeDescription
PropTypes.funcCalled when the user performs a swipe gesture on the physical controller, while hovering on this control. For example: _onSwipe(state, source) { if(state == 1) { // Swiped up } else if(state == 2) { // Swiped down } else if(state == 3) { // Swiped left } else if(state == 4) { // Swiped right }}For the mapping of sources to controller inputs, see the Events section.Unsupported VR Platforms: Cardboard(Android and iOS)

onTouch

TypeDescription
PropTypes.funcCalled when the user performs a touch action, while hovering on the control. Provides the touch state type, and the x/y coordinate at which this touch event has occurred.|State Value|Description||:------|:----------:||1| Touch Down: Triggered when the user makes physical contact with the touch pad on the controller. ||2| Touch Down Move: Called when the user moves around the touch pad immediately after having performed a Touch Down action. ||3| Touch Up: Triggered after the user is no longer in physical contact with the touch pad after a Touch Down action. |For example: _onTouch(state, touchPos, source) { var touchX = touchPos[0]; var touchY = touchPos[1]; if(state == 1) { // Touch Down } else if(state == 2) { // Touch Down Move } else if(state == 3) { // Touch Up }}For the mapping of sources to controller inputs, see the Events section.Unsupported VR Platforms: Cardboard(Android and iOS).

onTransformUpdate

PropTypes.funcA function that is invoked when the component moves and provides an array of numbers representing the component's position in world coordinates.

opacity

TypeDescription
PropTypes.numberA number from 0 to 1 that specifies the opacity of the container. A value of 1 translates into a fully opaque node while 0 represents full transparency.

passable

TypeDescription
PropTypes.boolIf true, then user is able to enter this ViroPortalScene through its ViroPortal.

position

TypeDescription
PropTypes.arrayOf(PropTypes.number)Cartesian position in 3D space, stored as [x, y, z].

rotation

rotationPivot

TypeDescription
PropTypes.arrayOf(PropTypes.number) Cartesian position in [x,y,z] about which rotation is applied relative to the component's position.

scale

TypeDescription
PropTypes.arrayOf(PropTypes.number)The scale of the container in 3D space, specified as [x,y,z]. A scale of 1 represents the current size of the container. A scale value of < 1 will make the container proportionally smaller while a value >1 will make the container proportionally bigger along the specified axis.

scalePivot

TypeDescription
PropTypes.arrayOf(PropTypes.number) Cartesian position in [x,y,z] from which scale is applied relative to the component's position.

transformBehaviors

TypeDescription
PropTypes.oneOfType([PropTypes.arrayOf(PropTypes.string),PropTypes.string])An array of transform constraints that affect the transform of the container. For example, putting the value "billboard" will ensure the container is facing the user as the user rotates their head on any axis. This is useful for having the container always face the user on a particular axis.Allowed values(values are case sensitive):|Value|Description||:------|:----------:||billboard| Billboard object on x,y,z axis ||billboardX| Billboard object on the x axis||billboardY| Billboard object on the y axis|

visible

TypeDescription
PropTypes.boolFalse if the container should be hidden. By default the container is visible and this value is true.

renderingOrder

TypeDescription
PropTypes.numberThis determines the order in which this Node is rendered relative to other Nodes. Nodes with greater rendering orders are rendered last. The default rendering order is zero. For example, setting a Node's rendering order to -1 will cause the Node to be rendered before all Nodes with rendering orders greater than or equal to 0.
