Collecting The Egg
A global message is sent, when a new player picks up the Dragon Egg. Using "/dragon_egg bearer", anyone can see who currently has the Dragon Egg.
Where is it?
Using "/dragon_egg bearer", you can see, where the Dragon Egg was last seen and who has it. The coordinates are randomized by default and you can configure the randomization radius.
Indestructible
The Dragon Egg is indestructible. When it takes damage, or is lost, it will teleport to the spawn and stays there until someone picks it up.
Highlighting
If configured this way (default), non-player entities will glow if they carry the Dragon Egg.
Chest Support
Even if someone puts the Dragon Egg in a chest, a shulker box inside a chest or even a bundle inside a shulker box inside a chest, the mod will never loose track. You can configure whether the coordinates will be shown.
BlueMap Support
There is builtin support for BlueMap, the beloved 3D Minecraft world viewer. If the current position is randomized, there will be an approximate area shown on the map. The marker is fully customizable.
