Similarly in escape vehicles

I've just now come across a plugin that already does this! l4d_rescue_vehicle_leave_timer by Harry Potter
I forgot the link: https://github.com/fbef0102/L4D1_2-P...le_leave_timer

Here is how they determined if a player is in a rescue vehicle:

PHP Code:

int entity = -1;
        while ((entity = FindEntityByClassname(entity, "trigger_multiple")) != -1)
        {
            int iHammerID = Entity_GetHammerId(entity);
            for(int i=0;i<MAX_DATAS;++i)
            {
                if( iHammerID == g_iData[i] )
                {
                    HookSingleEntityOutput(entity, "OnStartTouch", OnStartTouch);
                    HookSingleEntityOutput(entity, "OnEndTouch", OnEndTouch);
                    g_bFinalHasEscapeVehicle = true;
                    break;
                }
            }
        } 


OnStartTouch and OnEndTouch are simply functions where they set a per client boolean on whether the client is in the rescue vehicle. I'm more curious about the HammerID == g_iData[i] part though...

PHP Code:

bool LoadData()
{
    char sPath[PLATFORM_MAX_PATH];
    BuildPath(Path_SM, sPath, sizeof(sPath), CONFIG_SPAWNS);
    if( !FileExists(sPath) )
        return false;

    // Load config
    KeyValues hFile = new KeyValues("rescue_vehicle");
    if( !hFile.ImportFromFile(sPath) )
    {
        delete hFile;
        return false;
    }

    // Check for current map in the config
    char sMap[64];
    GetCurrentMap(sMap, sizeof(sMap));

    if( !hFile.JumpToKey(sMap) )
    {
        delete hFile;
        return false;
    }

    // Retrieve how many rescue entities
    int iCount = hFile.GetNum("num", 0);
    if( iCount == 0 )
    {
        delete hFile;
        return false;
    }
    
    // check limit
    if( iCount > MAX_DATAS )
        iCount = MAX_DATAS;
        
    //get hammerid of each rescue entity
    char sTemp[4];
    for( int i = 1; i <= iCount; i++ )
    {
        IntToString(i, sTemp, sizeof(sTemp));

        if( hFile.JumpToKey(sTemp) )
        {
            g_iData[i-1] = hFile.GetNum("hammerid", 0);
            g_iCvarTime = hFile.GetNum("time", 60);
            hFile.GoBack();
        }
    }

    delete hFile;
    return true;
} 


From what I can tell, they read a list of hammer IDs for each of the rescue vehicles' trigger_multiples off a provided data file, and then they check if the trigger_multiple's IDs of the current map match up. Perhaps a similar method could be adapted for telling whether or not a player is in grouping up points in elevators or otherwise?

Aren't the L4D_IsInFirstCheckpoint and L4D_IsInLastCheckpoint natives from Left 4 DHooks Direct enough to tell if a survivor is in either one of the saferooms?

That is true and I do plan on having molotov blocking just be based off of those.
