Class LightProbeVolume

Allows you to define a volume of light probes that will be used for indirect lighting. Lighting information in the scene will be interpolated from nearby probes to calculate the amount of indirect lighting at that position. It is up to the caller to place the light probes in areas where the lighting changes in order to yield the best results.

Constructors

Accessors

  • get active(): boolean
  • Activates or deactivates the component.

    Returns boolean

    The returned active state also accounts for the active state of the parent SceneObject.

  • set active(value): void
  • Parameters

    • value: boolean

    Returns void

  • get editorMetaData(): Settings
  • Get the editor meta data.

    Returns Settings

    The API is only valid in the editor.

  • get influenceVolume(): Immutable<AABox>
  • Determines the area over which the probes will be evaluated. Outside of this area no indirect diffuse lighting will be applied.

    Returns Immutable<AABox>

  • set influenceVolume(value): void
  • Parameters

    Returns void

  • get isActiveSelf(): boolean
  • Determines whether the component itself is active, without accounting for the active state of the parent scene object.

    Returns boolean

  • get isDestroyed(): boolean
  • Determines if the object has been destroyed.

    Returns boolean

  • get isRunning(): boolean
  • Determines if the component is currently active, enabled and running.

    Returns boolean

  • get priority(): number
  • The signed execution priority of the component.

    Determines order of execution of this component in relation to other components, higher priorities will execute earlier. The priority value determines the order of initialize, enable and update calls. Valid priorities are in the range [-100...100], other priorities are reserved for internal use.

    The priority should not be modified after onCreate has been called.

    The default priority for user implement components is -10. BuiltInComponent have a default priority of 0. However, instances that have dependencies or are a dependency to another component might have non zero default priorities. For example, the Camera component has a default priority of 50 as other components may depend on the camera being initialized early. The RigidBody component has a default priority of 22 and Joint components have a priority of 20 as the joint depends on fully initialized rigid bodies.

    Returns number

    If two components have the same priority, the order of execution is undefined, but deterministic as the system uses identifiers such as the internal type ID and UUID to guaranteed stable ordering.

  • set priority(value): void
  • Parameters

    • value: number

    Returns void

  • get uuid(): UUID
  • Returns a universally unique identifier that persists scene save/load.

    Returns UUID

Methods

  • Virtual

    Calculates bounds of the visible content for this component.

    Returns {
        box: AABox;
        sphere: Sphere;
    }

    An object with the bounding box and bounding sphere or null, if the component has no bounds.

  • Destroys the component, removing it from its scene object and stopping component updates.

    Parameters

    • Optionalimmediate: boolean

      If true the component will be fully destroyed immediately. This means that objects that are still referencing this component might fail. Normally destruction is delayed until the end of the frame to give other objects a chance to stop using it.

    Returns void

  • Returns the number of probes in the volume.

    Returns number

  • Retrieves the position of the probe at the specified index.

    Parameters

    • index: number

    Returns Vector3

  • Calls a parameterless method with the specified name, on the component.

    Parameters

    • name: string

      Name of the method to call.

    Returns boolean

    true if the method was invoked.

  • Virtual

    Called once when the component has been created.

    Returns void

    Called regardless of the state the component is in.

  • Virtual

    Called once just before the component is destroyed.

    Returns void

    Called regardless of the state the component is in.

  • Virtual

    Called every time a component is placed into the Stopped state.

    Returns void

    This method may be called during component destruction, if the component wasn't already in ScenePlayState.Stopped state during destruction. When called during destruction, it is called before onDestroy.

  • Virtual

    Called every time a component leaves the ScenePlayState.Stopped state.

    Returns void

    This method might be called during component creation, if the requirements for leaving the stopped state are met. One such case would be a component class that has the runInEditor attribute. When called during creation it is called after onInitialize.

  • Called at fixed time intervals (e.g. 60 times per frame). Only called if the component is in ScenePlayState.Playing state.

    Returns void

    RSX uses the fixed update to perform updates to sub-systems such as physics. Only implement this method if your logic depends on fixed updates (e.g. at 30hz) for stability.

  • Virtual

    Called once when the component first leaves the ScenePlayState.Stopped state.

    Returns void

    This method might be called during component creation, if the requirements for leaving the stopped state are met. One such case would be a component class that has the runInEditor attribute. When called during creation it is called after onCreate.

  • Virtual

    Called once per frame, after all other components received their onUpdate invocation. Only called if the component is in ScenePlayState.Playing state.

    Returns void

    This method should only be implemented if your component needs logic that implements on other component or SceneObject changes performend in onUpdate. An example could be a camera controller logic that updates in response to changes to the object that is being tracked.

  • Virtual

    Called when the script domain has been refreshed or when the component is initialized. During initialization it is called after onInitialize but before onEnable.

    Returns void

    This API will not be called in a deployment build.

  • Causes the information for all lights probes to be updated. You generally want to call this if you move the entire light volume or the scene around the volume changes.

    Returns void

  • Resizes the light probe grid and inserts new light probes, if the new size is larger than previous size. New probes are inserted in a grid pattern matching the new size and density parameters.

    Parameters

    • volume: Immutable<AABox>

      Axis aligned volume to be covered by the light probes.

    • OptionalcellCount: Immutable<Vector3>

      Number of grid cells to split the volume into. Minimum number of 1, in which case each corner of the volume is represented by a single probe. Higher values subdivide the volume in an uniform way.

    Returns void

  • Registers the coroutine for the specified component using the provided args as arguments.

    Type Parameters

    Parameters

    • coroutine: T

      The coroutine.

    • Rest...args: Parameters<T>

    Returns boolean

    true if the coroutine was registered.

    The coroutine will be called for the first time when the coroutine subsystem runs for update events. There is no guarantee with regards to the order of how coroutines are invoked. Coroutines are a great way for time-deferred or delayed system. To implement a coroutine simply add a generator method to your component and register it as coroutine:

    		public *myCoroutine(text:string)
    {
    const endTime:number = Time.realElapsed + 3;

    while(Time.realElapsed < endTime)
    {
    yield true;
    }

    Debug.log("This code will be invoked after 3 seconds with the text=" + text);
    }

    To register the function simply call

    		this.startCoroutine(this.myCoroutine, "Hello World!");
    

    The function will be invoked once the coroutine runs. The coroutine function can yield the program control flow by using the keyword yield. The coroutine will then stop execution at that point, and pick up the execution in the next update event, right after the yield keyword that caused the coroutine to pause.

    With helper functions such as waitForSeconds or waitForAsyncOp it is easy to create coroutines that pause for a set time interval.

  • Registers the coroutine for the specified component using the provided args as arguments.

    Type Parameters

    Parameters

    • coroutine: T

      The coroutine.

    • Rest...args: Parameters<T>

  • Stops all coroutines for the specified component.

    Returns void

    This API is only available for components that are registered in a scene.

  • Stops the coroutine for the specified component.

    Parameters

    Returns boolean

    true if the coroutine was registered.

  • Locates a rsx object by its sceneRuntimeID and UUID.

    Parameters

    • sceneRuntimeID: number

      The runtime ID of the SceneInstance of the object.

    • uuid: Const<UUID>

      The UUID of the object to retrieve.

    Returns SceneNode

    The object or null if no object with given sceneRuntimeID and uuid has been registered

Events

onCaptureCompleted: Event<[LightProbeCapture], void>

Fired when new capture data becomes available.

The current capture data is still available via lightProbeCapture and should be deleted manually from the project library, if it's not used by other sub systems. After this event, lightProbeCapture will return the newly captured data. The data passed to this event as first parameter should be immediately written to the project library.
