Quake3World

Hello, I want to do a Q3 arena mod. I need to do a double powerup, but I dont know how on it.
For start I please any step by step tut (I´m newbie).
Thx.

You want to add a new power-up? Search the game/ and cgame/ source for e.g. PW_REGEN or PW_HASTE, that should give you an indication of how power-ups are implemented in Q3A.

Ok, I think, that in g_active.c, how I do double jump function?

It is good idea. You must edit g_active.c,
bg_public.h, bg_misc.c, bg_pmove.c.
