## About The Pull Request Signals were initially only usable with component listeners, which while no longer the case has lead to outdated documentation, names, and a similar location in code. This pr pulls the two apart. Partially because mso thinks we should, but also because they really aren't directly linked anymore, and having them in this midstate just confuses people. [Renames comp_lookup to listen_lookup, since that's what it does](https://github.com/tgstation/tgstation/commit/102b79694fa8eb57ecf7b36032616a9e368ccced) [Moves signal procs over to their own file](https://github.com/tgstation/tgstation/commit/33d07d01fd336726b4f6f6f1b61bb0b3f11a00dc) [Renames the PREQDELETING and QDELETING comsigs to drop the parent bit since they can hook to more then just comps now](https://github.com/tgstation/tgstation/commit/335ea4ad081ec63c42cfa05856e582cca833af6e) [Does something similar to the attackby comsigs (PARENT -> ATOM)](https://github.com/tgstation/tgstation/commit/210e57051df63f88dac3dd83321236da825aae5e) [And finally passes over the examine signals](https://github.com/tgstation/tgstation/commit/65917658fb8a1e7d28ae23c9437a583d646f0302) ## Why It's Good For The Game Code makes more sense, things are better teased apart, s just good imo ## Changelog 🆑 refactor: Pulled apart the last vestiges of names/docs directly linking signals to components /🆑
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.
