dragPlane

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

PropTypes.oneOf(["FixedDistance", "FixedToWorld"])

Determines the behavior of drag if onDrag is specified.

The default value is "FixedDistance".

ignoreEventHandling

PropTypes.bool

When set to true, this control will ignore events and not prevent controls behind it from receiving event callbacks.

The default value is false.

materials

PropTypes.oneOfType([PropTypes.arrayOf(PropTypes.string),PropTypes.string])

An array of strings that each represent a material that was created via ViroMaterials.createMaterials().

onClick

React.PropTypes.func

Called when an object has been clicked.

Example code:

_onClick(position, source)  {
    // user has clicked the object
}

onClickState

React.PropTypes.func

Called for each click state an object goes through as it is clicked. Supported click states and their values are the following:

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.

onCollision

React.PropTypes.func

Called when this component's physics body collides with another component's physics body. Also invoked by ViroScene/ViroARScene's findCollisions... functions.

onDrag

React.PropTypes.func

Called 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
}

onFuse

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

React.PropTypes.func

Called when the user hovers on or off the control.

For example:

_onHover(isHovering, position, source)  {
    if(isHovering) {
        // user is hovering over the box
    } else {
        // user is no longer hovering over the box
    }
}

For the mapping of sources to controller inputs, see the Events section.

onPinch

React.PropTypes.func

Called 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:

This event is only available in AR.

onRotate

React.PropTypes.func

Called 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:

This event is only available in AR.

onScroll

React.PropTypes.func

Called 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.

_onSwipe(state, source)  {
    if(state == 1) {
        // Swiped up
    } else if(state == 2) {
        // Swiped down
    } else if(state == 3) {

scale

PropTypes.arrayOf(PropTypes.number)

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

scalePivot

PropTypes.arrayOf(PropTypes.number)

Cartesian position in [x,y,z] from which scale is applied relative to the component's position.

transformBehaviors

PropTypes.arrayOf(PropTypes.string)

An array of transform constraints that affect the transform of the object.

This is useful for icons or text where you'd like the box to always face the user at a particular rotation.

Allowed values(values are case sensitive):

type

React.PropTypes.oneOf(['dark','light'])

Spinner visual type for either a light or dark theme. This defaults to dark.

viroTag

PropTypes.string

A tag given to other components when their physics body collides with this component's physics body. Refer to physics for more information.

visible

PropTypes.bool

False if the spinner should be hidden. By default the spinner is visible and this value is true.

renderingOrder

PropTypes.number

This 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.

A function used with physics to apply an impulse (instantaneous) torque to an object with a physics body.

A function used with physics to set the velocity of an object with a physics body.

A wrapper function around the native component's setNativeProps which allow users to set values on the native component without changing state/setting props and re-rendering. Refer to the React Native documentation on Direct Manipulation for more information.

For example, setting position natively would look like this:

componentRef.setNativeProps({
    position : [0, 0, -1]
});
