Adding a Console Variable

I did this tut for q2, so I'm doing it again for q3. Enjoy (Not actually tested, let me know if this works properly]

This is a fairly easy one. No new files. It does require a few changes to a few files though. The cvar I will be adding will be called s_disableweapons Simply chage it to whatever you want your cvar to be

The first file anything will be added to is g_local.h Big surprise isn't it?.

Find the line which reads

And just under it put

extern means it isn't defined here but that it exists and can be used. As this is in g_local.h it can be used anywhere in the source.

Next open up g_main.c and find the line that reads

just under it insert

Thats it defined. now we need to initilize it. Find the line below

{ &g_allowVote, "g_allowVote", "1", 0, 0, qfalse }

Insert { &s_disableweapons, "s_disableweapons", "0", CVAR_SERVERINFO | CVAR_LATCH, 0, qfalse } just after it, before the };. Then add a comma (,) to the end of the line before the one you just added (oops missed this first time out. Thanks Assassin{SH})

The CVAR_SERVERINFO | CVAR_LATCH means that the cvar will be server side only, and will stick at a certain value till the map changes. The final field determines whether it's annouced that the cvar is changed. The "0" is the default value (it's stored as a string, so set it as a string)

Thats the basics of adding a cvar, heres how to use it

Check the value of s_disableweapons.integer in code where you want to check the cvar. easy don't you think?( You can also check s_disableweapons.value [for floating point values] and s_disableweapons.string [for strings. default max length is 265 characters])
