World Event: OnCvar(String/Color/Number)Changed

[Major Cooke]

Whenever a cvar changes, this function would be called and would give access to the name of the cvar, and the value changed.

This would allow for, say, an iterator to run and find specific entities and change a value on them. I.e. say we have a separate real-time difficulty adjustment option which allows changing the aggressiveness of custom AI. Using GetCvar often tends to drag down performance, whereas access to a local variable seems a lot cheaper.

I also suggest an actual event because not everyone would realize that they would otherwise have to build a NetworkEvent-managed CVar changer, and perform a lot of string splitting just to make it work for strings in particular.

User cvars would include the player number 0-7 while server cvars would set it to -1.

I'm honestly a bit dubious about this one.

Part of me wants to enable this only for CVARs that get defined in CVARINFO, unless the CVAR itself has CVAR_SERVERINFO or CVAR_USERINFO set on itself.

Or - enable it for any CVAR but only in the UI context, which means it would require net events in order to affect the playsim.

[Graf Zahl]

Agreed. Aside from that it's also rather invasive. The devil is buried in the details which I'd rather not deal with.

[Major Cooke]

CVARINFO is actually just what I need it for. But I understand. I'll just incorporate a network event version for my menu items.
