; Ham Sandwich module config file
; -
; Do not modify this file unless you know exactly what you're doing!
; -
; entry syntax is as follows:
; [modname]_[os]_key
; Example: the "use" key on TS running Linux would be "ts_linux_use"
; "modname" is the game directory, NOT the game description!
; eg: "ts", not "The Specialists"
; -
; Keys support either hexadecimal (MUST prefix with 0x) or base 10
; -
; Key types:
; * takedamage: this is the vtable index of the takedamage routine
; * use: this is the vtable index of the use routine
; * pev: this is the offset in bytes of the location of pev in the cbaseentity
; * classbase: this is the size in bytes of the cbaseentity base class LINUX ONLY
; NOTE: If the mod is compiled with GCC 3.3+ (NS is the only one
; I know of), then the classbase will always be 0x0
; -
; NOTE: If a mod is missing keys for a certain native, that particular native
; will not be loaded! Example: Say CS is missing the "takedamage" index
; but has the use and pev indexes. The hs_use and hs_pdata_cbase natives
; will be registered, but the hs_takedamage native will not be registered.
