EnderEggDropper
I’ve created this small plugin mainly for my network but i saw few server owners who are having the same issue as me.
This plugin design to have the dragon egg spawn more then once. It’s fully configurable on how you want the egg to spawn.
You can have it dropping the egg once the dragon is killed or have it place on top of the end portal. You can also configure on how you want the height of the egg to be on top of the end portal within the ender world.
Having the dragon egg placed into the world doesn’t work. It will keep making dragon eggs and make them infinite. If the height is set higher than portal it will just stack the eggs. https://streamable.com/lsvm8
A new version has been released for EnderEggDropper, it is available for download here.
Fixed Issue with task consistently placing the dragon egg also add EnderDragonPhaseTypes to make sure that nothing goes wrong, think of it like a safe guard.
