Here's it as a blank game mode, all compiles (for me)

I have not given them specific spawn points, but the skins are right.

pawn Code:

#include <a_samp>
new playerGang[MAX_PLAYERS];

#define GANG_NONE       0
#define GANG_GROVE      1
#define GANG_BALLA      2
#define GANG_VAGOS      3
#define GANG_AZTECAS    4

new gangLosAztecas[] = {114,115,116};


giveGangSkinAndWeapons(playerid) {
    GivePlayerWeapon(playerid,  5, 1); //Baseball bat
    GivePlayerWeapon(playerid, 24, 20); //Desert Eagle, 20x Ammo
