[Scenario]

I am not sure exactly, but you may wish to give this a try:

pawn Код:

stock IsPlayerInRangeOfPlayer(playerid, otherid, Float:range)
{
    new Float:Pos[3];
    GetPlayerPos(otherid, Pos[0], Pos[1], Pos[2]);
    if(IsPlayerInRangeOfPoint(playerid, range, Pos[0], Pos[1], Pos[2])) return true;
    return false;
}
