#include <amxmodx>

#include <fakemeta>

#include <cstrike>

#include <fun>

#include <hamsandwich>

#include <zombieplague>

#define is_valid_player(%1) (1 <= %1 <= 32)

new AK_V_MODEL[64] = "models/zombie_plague/v_golden_ak47.mdl"
new AK_P_MODEL[64] = "models/zombie_plague/p_golden_ak47.mdl"

new g_itemid1


 g_itemid1 = zp_register_extra_item("Golden Ak 47", 50, ZP_TEAM_HUMAN) 

}

public zp_extra_item_selected(player, itemid)

{
 if (itemid == g_itemid1)
 client_print(player, print_chat, "[ZP]获得Golden Ak 47")

}


give_weapon_ak47(id)

stock give_weapon_ak47(id) 
{
       give_item(id, "weapon_ak47")
}
