- Added channel-specific admin muting. Admins can now mute someone from IC (say, me and whisper), OOC, PRAY, ADMINHELP (adminhelp, admin pm and asay) and DEADCHAT (say while dead and dsay) - Added a (?) to adminhelps and prayers which displays the same quick overview that all the other (?)-s show, but for the person adminhelping or praying. git-svn-id: http://tgstation13.googlecode.com/svn/trunk@3888 316c924e-a436-60f5-8080-3fe189b3f50e

When somebody clicks a link in game, this Topic is called first.
|
|
It does the stuff in this proc and then is redirected to the Topic() proc for the src=[0xWhatever]
|
|
(if specified in the link). ie locate(hsrc).Topic()
|
|
|
|
Such links can be spoofed.
|
|
|
|
Because of this certain things MUST be considered whenever adding a Topic() for something:
|
|
- Can it be fed harmful values which could cause runtimes?
|
|
- Is the Topic call an admin-only thing?
|
|
- If so, does it have checks to see if the person who called it (usr.client) is an admin?
|
|
- Are the processes being called by Topic() particularly laggy?
|
|
- If so, is there any protection against somebody spam-clicking a link?
|
|
If you have any questions about this stuff feel free to ask. ~Carn
