Remarks

Dispatch a task for every entity that matches the filters and component types. Must be explicitly instantiated with the task type to dispatch. Construction arguments are deduced. Tasks must implement a ForEachEntity function that matches this task's component accessor types.

For example: struct FForEachEntity { void ForEachEntity(FMovieSceneEntityID InEntityID, const FMovieSceneFloatChannel& Channel); };

TComponentTypeID FloatChannelComponent = ...;

FGraphEventRef Task = FEntityTaskBuilder() .ReadEntityIDs() .Read(FloatChannelComponent) .SetStat(GET_STATID(MyStatName)) .SetDesiredThread(ENamedThreads::AnyThread) .Dispatch_PerEntity(EntityManager, nullptr); A pointer to the graph event for the task, or nullptr if this task is not valid (ie contains invalid component types that would be necessary for the task to run), or threading is disabled
