pawn Код:

stock PlayerToPoint(Float:radi, playerid, Float:x, Float:y)
{
    new Float:oldposx, Float:oldposy, Float:oldposz;
    new Float:tempposx, Float:tempposy;
    GetPlayerPos(playerid, oldposx, oldposy, oldposz);
    tempposx = (oldposx -x);
    tempposy = (oldposy -y);
    if (((tempposx < radi) && (tempposx > -radi)) && ((tempposy < radi) && (tempposy > -radi)))
    {
        return 1;
    }
    return 0;
}

now use it like

pawn Код:

if(PlayerToPoint(radi,playerid,x,y))
{
//your code
}
else
{
//your message
}

radi is your meter radius
