Hopefully this should make the evnt system a little faster, the tag-based events in particular.
Previously tag-baed events fired on all objects, but just returned early if the object wasn't the right tag; now, using the onTag and onUntag events the handlers are dynamically added and removed when tags change, reducing the overhead on each handler.
The big 3 per-frame events (onUpdate, onfixedUpdate, and onDraw) and also now handled using inlined
KEvent
s so that the routing overhead and extra function calls of looking up the named event handler inKEventHandler
goes away.
