[OZZI]

So I was wondering if there was a way to check for a flag within a script. I know there is alot of plugins that do it, like some VIP systems do. I was wondering how you do it and if so, if it could be done on this plugin:

#pragma semicolon 1
#pragma newdecls required

#include <sdkhooks>
#include <sdktools_entinput>
#include <sdktools_functions>
#include <sdktools_stringtables>
#if SOURCEMOD_V_MINOR >= 9
	#include <sdktools_variant_t>
#endif

enum

	HG_Generic = 0,
	HG_Head,
	HG_Chest,
	HG_Stomach,
	HG_Leftarm,
	HG_Rightarm,
	HG_Leftleg,
	HG_Rightleg
};

bool
	bCSGO,
	bEnable,
	bMode,
	g_bIsFired[MAXPLAYERS+1],
	g_bIsCrit[MAXPLAYERS+1][MAXPLAYERS+1],

int
	iType,
	g_iTotalSGDamage[MAXPLAYERS+1][MAXPLAYERS+1];
