I wish that Sponge can create an API for minigames.
The API would simply provide a way for plugins to only handle events in the game zone-This sounds simple but is actually a big headache.
They are very hesitant to add even the basic features needed to accomplish a minigame API (see here), so it’s not likely they would accept something even more constricting.
The only thing I can see them implementing are location based event filters, perhaps using Extent, but nothing beyond that.
