Add this to your gamemode:

pawn Код:

forward PlayerToPoint(Float:radi, playerid, Float:Px, Float:Py, Float:Pz);
public PlayerToPoint(Float:radi, playerid, Float:Px, Float:Py, Float:Pz)
{
    new Float:oldposx, Float:oldposy, Float:oldposz;
    new Float:tempposx, Float:tempposy, Float:tempposz;
    GetPlayerPos(playerid, oldposx, oldposy, oldposz);
    tempposx = (oldposx -Px);
    tempposy = (oldposy -Py);
    tempposz = (oldposz -Pz);
    if (((tempposx < radi) && (tempposx > -radi)) && ((tempposy < radi) && (tempposy > -radi)) && ((tempposz < radi) && (tempposz > -radi)))
    {
        return 1;
    }
    return 0;
}

Second errors with "Safe" is probably an anti-cheat system. With that I can't help you.
