Chasm.Dispatching

Latest NuGet version MIT License

Provides a CompiledDispatch<T> class, that pre-compiles the invocation delegate to use static dispatch instead of dynamic dispatch.

CompiledDispatch<T>

Many frameworks tend to use the following pattern:

public abstract class System {
    public abstract void Update(GameTime time);
}

foreach (System system in GetSystems())
    system.Update();

This often results in hundreds, or even thousands, of virtual calls. It's fine if these systems aren't called often, but if they are (e.g. in a game with ECS), it could cost the program entire seconds of CPU time! CompiledDispatch<T> aims to alleviate this problem, by compiling the methods statically (compilation only takes a few dozen microseconds).

CompiledDispatch<GameTime> dispatch = new();

// all the ways methods can be added:
dispatch.Add(clockSystem.Update); // ← preferred
dispatch.Add(timerSystem, "Update");
dispatch.Add(npcSystem, npcSystemUpdateMethod);

dispatch.Compile();
dispatch.Dispatch(new GameTime(1000));

The compiled method would essentially look like this:

[MethodImpl(MethodImplOptions.NoInlining)]
static void Dispatch_Generated(GameTime time)
{
    ClockSystem clockSystem = /*…*/;
    clockSystem.Update(time);
    TimerSystem timerSystem = /*…*/;
    timerSystem.Update(time);
    NpcSystem npcSystem = /*…*/;
    npcSystem.Update(time);
}

All of the static Update calls will have the ability to be inlined or even completely optimized away!

Don't update the collection of dispatched methods too often!
Otherwise, the performance gain won't be worth the extra compilation time.
Ideally, you'd populate the collection just once, and then only call the compiled method.
