## About The Pull Request
Revived my old PR https://github.com/tgstation/tgstation/pull/68901
Replaces the annoying tgui alert popup "Do you want to be X? | Yes | No
| Never for this round" that is hard to read and steals window focus,
with a nice clean alert in the top right that counts down. If it's the
same event/mob they stack with 2x, 3x, etc. It also shows how many
candidates/ghosts are signed up.
The poll alerts have screentips too, they countdown and show if you're
signed up, how many people are signed up, if you chose "never for this
round" (which is cancelable)
## Why It's Good For The Game
Way easier to see what role is available, you get a nice pic of the role
and get it's name in big text, you can cancel "never for this round",
and you can cancel signing up for a role before the timer is up
## Changelog
🆑
refactor: Ghost roles now offer ghosts a clickable poll button. Ghosts
can select a role, deselect it, alt-click it for "Never For This Round",
can cancel "Never", can see the countdown, and can see how many other
people are signed up for the role poll.
/🆑
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.
