Strange, unfortunatelly I am a total noob when it come to these kinds of entity errors.

Is this happening on stock or custom campaigns?
Or a particular map!?

With Sourcemod everything is possible.
There are a other plugins messing with tanks and witches.
MB you can request a plugin where you can put individual spawn points and amounts an a per map cfg basis.

That would be indeed cool to spawn tanks and witches on some unusual places.

My English is not good, I don't know how to ask

[ZBzibing]

Can you add a hint?
When the tank appeared, the security door was locked. When the player tried to open the security door, a prompt message appeared

Haven't tested it, mabye replace the Event_PlayerDeath Event_PlayerSpawn and then hook the opendoor event.
And then make a message.
Not sure if this works, haven't tested it.

PHP Code:

public void Event_PlayerSpawn(Event event, const char[] name, bool dontBroadcast) 
{
    int UserId = event.GetInt("userid");
    if (UserId != 0) {
        int client = GetClientOfUserId(UserId);
        if (client != 0) {
            if (IsTank(client) && !g_bIsTankAlive) {
                g_bIsTankAlive = true;
                Command_Play("ui\\pickup_secret01.wav");
                Command_Play("player\\tank\\voice\\yell\\hulk_yell_4.wav");
                if(!IsFinaleMap()) {
                    ControlDoor(iCheckpointDoor, LOCK);
                    PrintToChatAll("[SM] A Tank spawned. The safehouse is locked!");
                    HookEvent("door_open", Event_DoorOpen);
                }
                else {
                    PrintToChatAll("[SM] A Tank spawned!");
                }
            }
        }
    }
}

public void Event_PlayerDeath(Event hEvent, const char[] name, bool DontBroadcast)
{
    int client = GetClientOfUserId(hEvent.GetInt("userid"));
    if (client && IsClientInGame(client)) {
        if (IsTank(client)) {
            int Tankcount = 0; 
               for (int i = 1; i <= MaxClients; i++) 
                if (IsClientConnected(i) && IsClientInGame(i) &&  IsPlayerAlive(i) && GetEntProp(i, Prop_Send, "m_zombieClass") == 5) Tankcount++; 
            if(Tankcount==0){
                if(!IsFinaleMap()) {
                    PrintToChatAll("[SM] The Tank is dead! The safehouse is open!");
                    ControlDoor(iCheckpointDoor, UNLOCK);
                UnhookEvent("door_open", Event_DoorOpen);
                }
                else {
                PrintToChatAll("[SM] The Tank is dead!");    
                }
                g_bIsTankAlive = false;
            }
        }
    }
}


public void Event_DoorOpen(Event event, const char[] name, bool dontBroadcast)
{
        int client = GetClientOfUserId(event.GetInt("userid"));
        if( client )
        {
                if( IsClientInGame(client) )
                {
                    PrintCenterText(client, "A Tank is alive, the door is locked!!!");

                }
            }
        }
}

"IsClientConnected(i) && IsClientInGame(i)" - There's no need to check "IsClientConnected" because "IsClientInGame" already does that.

If you want to support L4D2, the "m_zombieClass" for tank is 8 in L4D2 and 5 in L4D1. Suggest something like "g_iClassTank = g_bLeft4Dead2 ? 8 : 5;" in plugin start, then checking against that var.
