Class: GSplatComponent
The GSplatComponent enables an Entity to render 3D Gaussian Splats. Splats are always
loaded from Assets rather than being created programmatically. The asset type is
gsplat which are in the .ply file format.
Properties

Gets the array of layer IDs (Layer#id) to which this gsplat belongs.
Returns
number
Set Signature
set layers(value: number[]): void
Sets an array of layer IDs (Layer#id) to which this gsplat should belong. Don't push, pop, splice or modify this array. If you want to change it, set a new one instead.

Inherited from
Component.fire
hasEvent()
hasEvent(name: string): boolean
Test if there are any handlers bound to an event name.
Parameters
name
string
The name of the event to test.
Returns
boolean
True if the object has handlers bound to the specified event name.
Example

Inherited from
Component.hasEvent
hide()
hide(): void
Stop rendering this component without removing its mesh instance from the scene hierarchy.
Returns
void
off()
off(
name?: string,
callback?: HandleEventCallback,
scope?: any): EventHandler
Detach an event handler from an event. If callback is not provided then all callbacks are unbound from the event, if scope is not provided then all events with the callback will be unbound.
Parameters
name?
string
Name of the event to unbind.
callback?
HandleEventCallback
Function to be unbound.
scope?
any
Scope that was used as the this when the event is fired.
Returns
Self for chaining.
Example
const handler = () => {}
obj.on('test', handler)
obj.off() // Removes all events
obj.off('test') // Removes all events called 'test'
obj.off('test', handler) // Removes all handler functions, called 'test'
obj.off('test', handler, this) // Removes all handler functions, called 'test' with scope this

Component.off
on()
on(
name: string,
callback: HandleEventCallback,
scope?: any): EventHandle
Attach an event handler to an event.
Parameters
name
string
Name of the event to bind the callback to.
callback
HandleEventCallback
Function that is called when event is fired. Note the callback is limited to 8 arguments.
scope?
any = ...
Object to use as 'this' when the event is fired, defaults to current this.
Returns
Can be used for removing event in the future.
Examples
obj.on('test', (a, b) => {
console.log(a + b)
})
obj.fire('test', 1, 2) // prints 3 to the console
const evt = obj.on('test', (a, b) => {
console.log(a + b)
})
// some time later
evt.off()
Inherited from
