Here's one possible approach:

1. Keep track of the weapons that each player has been given by the server using an array of length 13.
2. When a player is given a weapon by the server, store the ID of that weapon in their array to indicate that they are supposed to have that gun.
3. When a player damages another player, make sure that they are expected to have the weapon they're using.

The required code would look something like this:

Код:

#define MAX_PLAYERS 32 //Player capacity of your server

new weapons[MAX_PLAYERS][13]; //Store the weapon each player should have in a specific slot

//Function to give players a weapon
giveGun(playerid, weaponid, ammo)
{
	GivePlayerWeapon(playerid, weaponid, ammo);
	
	//Keep track of what weapons the player has
	for(new i = 0; i < 13; i++)
	{
		new temp;
		GetPlayerWeaponData(playerid, i, weapons[playerid][i], temp);
	}
}

public OnPlayerGiveDamage(playerid, damagedid, Float:amount, weaponid, bodypart)
{
	new bool:allowedWeapon = false;
	for(new i = 0; i < 13; i++)
	{
		if(weapons[playerid][i] == weaponid)
		{
			allowedWeapon = true;
			break;
		}
	}
	
	if(allowedWeapon == false)
	{
		//We did not expect the player to have this weapon, they must have cheated!
		//Do something.
	}

	return 1;
}

In order for this code to function without false positives, it will be necessary to prevent players from acquiring weapons using the default ammunition, add your own checkpoint etc.
