Remarks

Dispatch a task for every allocation 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 ForEachAllocation function that matches this task's component accessor types.

For example: struct FForEachAllocation { void ForEachAllocation(FEntityAllocation* InAllocation, const TFilteredEntityTask< FEntityIDAccess, TRead >& InputTask); };

TComponentTypeID FloatChannelComponent = ...;

FGraphEventRef Task = FEntityTaskBuilder() .ReadEntityIDs() .Read(FloatChannelComponent) .SetStat(GET_STATID(MyStatName)) .SetDesiredThread(ENamedThreads::AnyThread) .Dispatch_PerAllocation(EntityManager, Prerequisites); 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
