So I want a plugin like query facade (if you are able to update it I prefer this plugin) that I will be able to change the max players, the player count and the motd of my server.
You can write your own plugin, it should be easily possible to set the player count and max players through QueryRegenerateEvent using $event->setPlayerCount() and $event->setMaxPlayerCount(), you can change the MOTD using PHP: $this->getServer()->getNetwork()->setName("Your dynamic Message Of The Day");
I wouldn't display wrong information to my players to make they think that there are X players online. Nor I think it will help in attracting the attention of more players. But I would do what Lifeboat does: merge all players online of their network. Though, it wouldn't be bad for someone to create an add-on plugin or a built-in feature for QueryFacade to update the fake players online at certain intervals, and in certain ranges.
I really think you shouldnt have a fake online player count. Feel free to have a fake max player count, but fake online players is misleading and if someone joins your server which says 40 players and there is 2 players online, do you think they will ever join that server again?
Well, I do not really care for the online players. The max players count is what I need. Just some code would complete this request...
i wouldnt mind if you use it to display fake information because as said previously, you would just be digging your own grave and i only replied just to show how my useless opinion without contributing anything towards the topic like everyone else is doing here
How is this relevant to what the OOP asked? This was a question, not a "whats your opinion about my question?"
No it wouldn't - you need to listen to the QueryRegenerateEvent and then change the event data using PHP: $event->setMaxPlayerCount(100);
