UE5.1 Mass Processor issue

Development Programming & Scripting C++

The execute function has changed since then

it is now

virtual void Execute(FMassEntityManager& EntityManager, FMassExecutionContext& Context);

Haven’t tested it out but it compiles ok

}

Oh and the build file needs the following modules:
MassEntity, MassCommon, MassSpawner

PublicDependencyModuleNames.AddRange(new string[] { "Core", "CoreUObject", "Engine", "InputCore",  "MassEntity", "MassCommon", "MassSpawner" });
