/*
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
