include zcmd first

pawn Code:

#include <zcmd>

and ofc define the color thx for Bravo for reminding me

pawn Code:

#define COLOR_RED 0xFF0000

pawn Code:

CMD:wpack(playerid, params[]) // this how you  need to preform the command
{
    if(GetPlayerMoney(playerid) < 1000)
    return SendClientMessage(playerid, COLOR_RED, "You don't have enough cash to buy /wpack");
    GivePlayerMoney(playerid, -1000); //this takes the money from the player so it wont be free
    GivePlayerWeapon(playerid, 10, 0); //You can change the weapons if you want
    GivePlayerWeapon(playerid, 24, 500); //those functions are the weapons
    GivePlayerWeapon(playerid, 26, 500);
    GivePlayerWeapon(playerid, 32, 500);
    GivePlayerWeapon(playerid, 31, 500);
    GivePlayerWeapon(playerid, 34, 500);
    SendClientMessage(playerid, COLOR_RED, "You have succesfully used /wpack!"); //this shows that the cmd works
    return 1;
}

Hope it helped you guys have a nice day

Nice Command I'm impressed of it simple but efficient.One more thing:you gotta define the color in order for it to work.Newbies will get undefined simbol error.Color define:

pawn Code:

#DEFINE COLOR_RED color code

Small Update: Now if you buy a pack you cannot buy it if you have less then 1000 cash

You forgot to close the text.

pawn Code:

// SendClientMessage(playerid, COLOR_RED, "You don't have enough cash to buy /wpack"); // <--
SendClientMessage(playerid, COLOR_RED, "You don't have enough cash to buy /wpack);

To be honest, I don't see a weapon system as you stated in the title, but a command which gives you 5 weapons.

Weapon systems can be made from commands too
