Simple example:

PHP код:

// Init checker for players
static bool:cheater[MAX_PLAYER_NAME];
stock GivePlayerValidWeapon(playerid, weaponid, ammo) {    
     new 
         str[16]
     ;
     format(str, sizeof(str), "WEAPON%d", weaponid);
     SetPVarInt(playerid, str, weaponid);
     format(str, sizeof(str), "AMMO%d", weaponid);
     SetPVarInt(playerid, str, GetrPVarInt(playerid, str) + ammo);
     GivePlayerWeapon(playerid, weaponid, ammo);   
}
stock GetPlayerValidAmmo(playerid) {
     new weaponid = GetPlayerWeapon(playerid);
     if (!weaponid) return 0;
     new 
         str[16]
     ;
     format(str, sizeof(str), "AMMO%d", weaponid);
     return GetPVarInt(playerid, str);
}
stock GetPlayerValidWeapon(playerid) {
     new weaponid = GetPlayerWeapon(playerid);
     if (!weaponid) return 0;
     new 
         str[16]
     ;
     format(str, sizeof(str), "WEAPON%d", weaponid);
     return GetPVarInt(playerid, str);
}
stock ResetPlayerValidWeapon(playerid) {
     new 
         str[16]
     ;
     for (new i; i < 47; i++) {
         format(str, sizeof(str), "AMMO%d", i);
         DeletePVar(playerid, str);
         format(str, sizeof(str), "WEAPON%d", i);
         DeletePVar(playerid, str);
     }
}
forward KickPlayer(playerid);
public KickPlayer(playerid) {
     Kick(playerid);
     return true;
}
public OnPlayerSpawn(playerid) {
     GivePlayerValidWeapon(playerid, 31, 200); // Give M4 ammo x200
     return true;
}
public OnPlayerDisconnect(playerid, reason) {
     ResetPlayerValidWeapon(playerid); // Reset all weapons
     cheater[playerid] = false;
     return true;
}
public OnPlayerUpdate(playerid) {
     if (GetPlayerValidWeapon(playerid) != GetPlayerWeapon(playerid) && !cheater[playerid]) { // Cheсk hack weapon
           new
                msg[256],
                name[MAX_PLAYER_NAME],
                weapon[24]
           ;
           GetPlayerName(playerid, name, sizeof(name));
           GetWeaponName(GetPlayerWeapon(playerid), weapon, sizeof(weapon));
           format(msg, sizeof(msg), "Srever: %s(%d) has kicked for WeaponHack %s", name, playerid, weapon);
           SendClientMessageToAll(-1, msg);
           SetTimerEx("KickPlayer", 200, 0, "i", playerid); // Kick cheater
           cheater[playerid] = true;
     }
     return true;
}

PVars are way too slow, especially if coupled with format and OnPlayerUpdate. I'd rather use an array like:

pawn Код:

gPlayerWeaponData[MAX_PLAYERS][47]

And then use something like:

pawn Код:

SafeGivePlayerWeapon(playerid, weaponid, ammo)
{
    gPlayerWeaponData[playerid][weaponid] = ammo;
    return GivePlayerWeapon(playerid, weaponid, ammo);
}

Next, check the example for OnPlayerWeaponChange on the wiki page of OnPlayerUpdate (which regrettably also uses PVars, but that aside). If the player changes to a weapon for which he has no ammo then the weapon is being hacked in. Take note to exclude parachutes and detonators as these are given automatically by the game.

In this case, the speed is not so important. In addition, they global and I can use these functions filterscripts

If you use an array, then the function GivePlayerValidWeapon
It will not be accessible from filterscript.

For example, I have a script that gives a weapon, and I have it saved as filterscript

If I try to do

GivePlayerValidWeapon(playerid, 31, 20);

What I did not keep my arms. That's why I gave the example is to PVars

PS: I have a standard example of a wiki is not use for a long time because I know it
