postProcess property

PostProcess? get postProcess

A PostProcess that is applied to the world of a camera.

Do note that only one postProcess can be active on the camera at once. If the postProcess is set to null, the previous post process will be removed. If the postProcess is set to not null, it will be added to the camera, and any previously active post process will be removed.

Implementation

PostProcess? get postProcess =>
    children.query<PostProcessComponent>().firstOrNull?.postProcess;
set postProcess (PostProcess? postProcess)

Implementation

set postProcess(PostProcess? postProcess) {
  final postProcessComponents = children
      .query<PostProcessComponent>()
      .toList();
  final queuedPostProcessAdds = findGame()?.queue
      .where(
        (event) =>
            event.kind == LifecycleEventKind.add &&
            event.child is PostProcessComponent,
      )
      .map((event) => event.child!);
  removeAll([...postProcessComponents, ...?queuedPostProcessAdds]);
  if (postProcess != null) {
    add(PostProcessComponent(postProcess: postProcess));
  }
