I created a simple function for you

pawn Код:

stock SendNearMessage(playerid, color, string[], Float:radius)
{
    new Float:Position[3];
    GetPlayerPos(playerid,Position[0],Position[1],Position[2]);

    for(new i; i <= MAX_PLAYERS; i++)
    {
        if(!IsPlayerConnected(playerid)) continue;

        if(IsPlayerInRangeOfPoint(i,radius, Position[0],Position[1],Position[2]))
            return SendClientMessage(i, color, string);
    }
    return 1;
}

Replace

pawn Код:

SendClientMessageToAll(COLOR_PURPLE, RandomMSG[randMSG]);

To

pawn Код:

SendNearMessage(playerid, COLOR_PURPLE, RandomMSG[randMSG], 15.0);
