squeaking objects including air horns and clockwork boots now have a default 1 second cooldown. squeaking objects crossing each other will on average only allow 3 squeaks to occur, because if byond is literally running out of sound channels you know the fun has went too far
Datum Component System (DCS)
Concept
Loosely adapted from /vg/. This is an entity component system for adding behaviours to datums when inheritance doesn't quite cut it. By using signals and events instead of direct inheritance, you can inject behaviours without hacky overloads. It requires a different method of thinking, but is not hard to use correctly. If a behaviour can have application across more than one thing. Make it generic, make it a component. Atom/mob/obj event? Give it a signal, and forward it's arguments with a SendSignal() call. Now every component that want's to can also know about this happening.
See this thread for an introduction to the system as a whole.
