Methods
dispose()
dispose():
void
Defined in: src/core/Script.ts:263
Called when the script is removed from the scene. Opposite of init.
Returns
void
Inherited from
init()
init(
_?):void|Promise<void>
Defined in: src/core/Script.ts:108
Initializes an instance with XR controllers, grips, hands, and default options. We allow all scripts to quickly access its user (e.g., user.isSelecting(), user.hands), world (e.g., physical depth mesh, lighting estimation, and recognized objects), and scene (the root of three.js's scene graph). If this returns a promise, we will wait for it.
Parameters
_?
object
Returns
void | Promise<void>
Inherited from
initPhysics()
initPhysics(
_physics):void|Promise<void>
Defined in: src/core/Script.ts:118
Enables depth-aware interactions with physics. See /samples/advanced/ballpit
Parameters
_physics
Returns
void | Promise<void>
Inherited from
onHoverEnter()
onHoverEnter(
_event):void
Defined in: src/core/Script.ts:215
Called when a source starts hovering over this object.
Parameters
_event
The hover source, target, surface, and intersection.
Call event.stopPropagation() to stop bubbling to ancestor Scripts.
Returns
void
Inherited from
onHoverExit()
onHoverExit(
_event):void
Defined in: src/core/Script.ts:221
Called when a source stops hovering over this object.
Parameters
_event
The hover source, target, surface, and intersection.
Call event.stopPropagation() to stop bubbling to ancestor Scripts.
Returns
void
Inherited from
onHovering()
onHovering(
_event):void
Defined in: src/core/Script.ts:227
Called while a source hovers over this object.
Parameters
_event
The hover source, target, surface, and intersection.
Call event.stopPropagation() to stop bubbling to ancestor Scripts.
Returns

Inherited from
onKeyDown()
onKeyDown(
_event):void
Defined in: src/core/Script.ts:158
Called on keyboard keypress.
Parameters
_event
Event containing .code to read the keyboard key.

Parameters
_event
Returns

Inherited from
onLongSelect()
onLongSelect(
_event):void
Defined in: src/core/Script.ts:152
Called when an object selection reaches the long-select delay.
Parameters
_event
Returns
void
Inherited from
onObjectGrabbing()
onObjectGrabbing(
_event):void
Defined in: src/core/Script.ts:253
Called every frame a hand is grabbing this object.
Parameters
_event
Returns
void
Inherited from
TransformScript.onObjectGrabbing
onObjectGrabEnd()
onObjectGrabEnd(
_event):void
Defined in: src/core/Script.ts:258
Called when a hand stops grabbing this object. This ends built-in direct-touch manipulation without ending contact.
Parameters
_event
Returns
void
Inherited from
TransformScript.onObjectGrabEnd
onObjectGrabStart()
onObjectGrabStart(
_event):void
Defined in: src/core/Script.ts:249
Called when a hand starts grabbing this object (touching + pinching). A grab starts built-in direct-touch manipulation when enabled.
Parameters
_event
Returns
void
Inherited from
TransformScript.onObjectGrabStart
onObjectLongSelect()
onObjectLongSelect(
_event):void
Defined in: src/core/Script.ts:203
Called once when a captured selection is held for the long-select delay. Manipulation captures do not emit this callback.
Parameters
_event
The controller and completed hold duration.
Call event.stopPropagation() to stop bubbling to ancestor Scripts.
Returns
void
Inherited from
TransformScript.onObjectLongSelect
onObjectManipulate()
onObjectManipulate(
_event):void
Defined in: src/core/Script.ts:209
Called for each phase of an automatic object manipulation. Call
event.stopPropagation() to stop bubbling. Calling preventDefault()
on a start event suppresses the automatic action.
Parameters
_event
Returns
void
Inherited from
TransformScript.onObjectManipulate
onObjectSelectEnd()
onObjectSelectEnd(
_event):void
Defined in: src/core/Script.ts:196
Called when a source stops selecting the object this Script represents.
Parameters
_event
The completed state and end reason.
Call event.stopPropagation() to stop bubbling to ancestor Scripts.
Returns
void
Inherited from
TransformScript.onObjectSelectEnd
onObjectSelectStart()
onObjectSelectStart(
_event):void
Defined in: src/core/Script.ts:190
Called when a source starts selecting the object this Script represents.
Parameters
_event
event.target is the logical object and
event.source.controller identifies the controller.
Call event.stopPropagation() to stop bubbling to ancestor Scripts.
Returns
void
Inherited from
TransformScript.onObjectSelectStart
onObjectTouchEnd()
onObjectTouchEnd(
_event):void
Defined in: src/core/Script.ts:244
Called when a hand's index finger stops touching this object. This ends the default selection lifecycle after the touch callback.
Parameters
_event
Returns
void
Inherited from
TransformScript.onObjectTouchEnd
onObjectTouching()
onObjectTouching(
_event):void
Defined in: src/core/Script.ts:239
Called every frame that a hand's index finger is touching this object. The object remains selected during these frames unless touch selection was prevented when contact started.
Parameters

onObjectTouchStart()
onObjectTouchStart(
_event):void
Defined in: src/core/Script.ts:233
