What does mapping have to do with this?

Anyway: You need to use the callback called "OnPlayerConnect". This has a single parameter of (playerid). You can view the wiki page here: https://sampwiki.blast.hk/wiki/OnPlayerConnect

pawn Код:

public OnPlayerConnect(playerid)
{
    
    return 1;
}

You will also need the GivePlayerWeapon function, which has three parameters: (playerid, weaponid, ammo). You can view the wiki page here: https://sampwiki.blast.hk/wiki/GivePlayerWeapon

pawn Код:

GivePlayerWeapon(playerid, weaponid, ammo);

Combining those two will give you:

pawn Код:

public OnPlayerConnect(playerid)
{
     GivePlayerWeapon(playerid, weaponid, ammo);
     return 1; //Always return 1 to allow this callback to continue into filterscripts.
}

You will obviously need to fill out weaponid and ammo yourself, as I don't know what weapon/ammo amount you want. You can get the weaponid from the wiki, and the ammo amount is up to you.
