Hi.

This is very limiting code, as you'll have to declare (AREAS) * 2 arrays of 2 cells for all the areas in your mode, MANUALLY, write the code for each manually.. why not teach new people a better way?

pawn Code:

static mapZones[MAX_GANGZONES] = {-1, ...},
        mainTimer;

new Float: gZones[][4] = 
{
    {-838.9635, 1163.5237, 569.5944, 2742.9941}
//  {minX,  minY,   maxX,   maxY}
};

forward public MainTimer();

public OnGameModeInit()
{
    for(new i = 0; i < sizeof(gZones); i++)
        mapZones[i] = GangZoneCreate(gZones[i][0], gZones[i][1], gZones[i][2], gZones[i][3]);
    
    mainTimer = SetTimer("MainTimer", 1000, true); 
    
    return 1;
}

public OnPlayerDisconnect(playerid)
{   
    for(new i = 0; i < sizeof(gZones); i++)
        GangZoneHideForPlayer(playerid, mapZones[i]);
        
    return 1;
}

public OnPlayerConnect(playerid)
{
    for(new i = 0; i < sizeof(gZones); i++)
        GangZoneShowForPlayer(playerid, MapZone, 0xBBBBBB88);
        
    // Again, per zone colors can be added in the array too!
    
    return 1;
}

public MainTimer()
{
    new Float:HP; // player health
    for(new i= 0; i < MAX_PLAYERS; i++) // loops through players
    {
        if(IsPlayerConnected(i)) //You can add more exceptions here, where you don't want boundaries e.g. dms, duels, etc.
        {
            for(new j = 0; j < sizeof(gZones); j++)
            {
                if(IsPlayerInArea(i, gZones[j][0], gZones[j][1], gZones[j][2], gZones[j][3] ) != 1) // check if the player is not in the area/zone.
                {
                    GetPlayerHealth(i, HP); // gets player health
                    SetPlayerHealth(i, HP-5); // reduces -5%, every 1 second.
                    GameTextForPlayer(i, "~r~Stay inside boundaries~n~or you will be killed!", 3000, 3); // Shows a game text for the player who got out of the boundaries, 3000 = 3 seconds, 3 = font style.
                }
            }
        }
    }
}

I've just added some code, and copied some of yours. Sorry, lazy me
