Use something like:

pawn Код:

public OnPlayerWeaponShot(playerid, weaponid, hittype, hitid, Float:fX, Float:fY, Float:fZ)
{
    new Hits, Hitwinner;
    if(hittype == BULLET_HIT_TYPE_OBJECT)
    { 
        if(hitid == Objectid)//if he hitted the objectid, don't put the id here, use something like new Objectid; and use Objectid = CreateDynamic........ while creating object.
        { 
            Hits++
            Hitwinner = playerid;
            If(Hits == 20)
            {
                GivePlayerMoney(Hitwinner, 1000);
                Hits=0;
            }
        }
    }
    
    return 1;
}
