Pointers

Description

Supported Script Types: Interface Scripts • Client Entity Scripts • Avatar Scripts

The Pointers API lets you create, manage, and visually represent objects for repeatedly calculating intersections with avatars, entities, and overlays. Pointers can also be configured to generate events on entities and overlays intersected.

Methods

Name Return Value Summary
createPointer number

Creates a new ray, parabola, or stylus pointer. The pointer can have a wide range of behaviors depending on the properties specified. For example, a ray pointer may be a static ray pointer, a mouse ray pointer, or joint ray pointer.

Warning: Pointers created using this method currently always intersect at least visible and collidable things but this may not always be the case.

disablePointer None

Disables and hides a pointer. Disabled pointers do not update their pick results or generate events.

editRenderState None

Edits a render state of a ray or parabola pointer, to change its visual appearance for the state when the pointer is intersecting something.

Note: You can only edit the properties of the existing parts of the pointer; you cannot change the type of any part.

Note: You cannot use this method to change the appearance of a default render state.

Note: Not able to be used with stylus pointers.

enablePointer None

Enables and shows a pointer. Enabled pointers update their pick results and generate events.

getPointerProperties Pointers.RayPointerProperties | Pointers.ParabolaPointerProperties | object

Gets information about a pointer.

getPointers Array.<number>

Gets all pointers which currently exist, including disabled pointers.

getPointerScriptParameters Pointers.RayPointerProperties | Picks.ParabolaPointerProperties | Picks.StylusPointerProperties

Gets the parameters that were passed in to Pointers.createPointer to create the pointer when the pointer was created through a script.

Note: These properties do not reflect the current state of the pointer. To get the current state of the pointer, see Pointers.getPointerProperties.

getPrevPickResult RayPickResult | ParabolaPickResult | StylusPickResult

Gets the most recent intersection of a pointer. A pointer continues to be updated ready to return a result, as long as it is enabled, regardless of the render state.

isLeftHand boolean

Checks if a pointer is associated with the left hand: a ray or parabola pointer with joint property set to "_CONTROLLER_LEFTHAND" or "_CAMERA_RELATIVE_CONTROLLER_LEFTHAND", or a stylus pointer with hand property set to 0.

isMouse boolean

Checks if a pointer is associated with the system mouse: a ray or parabola pointer with joint property set to "Mouse".

isPointerEnabled boolean

Gets the enabled status of a pointer. Enabled pointers update their pick results and generate events.

isRightHand boolean

Checks if a pointer is associated with the right hand: a ray or parabola pointer with joint property set to "_CONTROLLER_RIGHTHAND" or "_CAMERA_RELATIVE_CONTROLLER_RIGHTHAND", or a stylus pointer with hand property set to 1.

removePointer None

Removes (deletes) a pointer.

setIgnoreItems None

Sets a list of entity and avatar IDs that a pointer should ignore during intersection.

Note: Not used by stylus pointers.

setIncludeItems None

Sets a list of entity and avatar IDs that a pointer should include during intersection, instead of intersecting with everything.

Note: Stylus pointers only intersect with items in their include list.

setLength None

Sets the length of a pointer.

Note: Not used by stylus pointers.

setLockEndUUID None

Locks a pointer onto a specific entity or avatar.

Note: Not used by stylus pointers.

setPrecisionPicking None

Sets whether or not a pointer should use precision picking, i.e., whether it should pick against precise meshes or coarse meshes. This has the same effect as using the PICK_PRECISE or PICK_COARSE filter flags.

setRenderState None

Sets the render state of a pointer, to change its visual appearance and possibly disable or enable it.
