This issue is different from MC-174759.
MC-174759 mainly states that the dragon egg can teleport to -Y.
Can confirm.
I am able to confirm this behavior in 21w38a though, this may be a duplicate of
MC-229536. Please correct me if I'm wrong as I'm not 100% sure.@[Mod] Avoma
MC-229536is about the dragon eggs can teleport in the air.This issue mainly focuses on whether to check that there is void below the dragon eggs.
Ahh, I see. Thank you for this info
Can confirm in 1.18.1.
Here's a code analysis of this issue.
Code Analysis:
The following is based on a decompiled version of Minecraft 1.18.1 using MCP-Reborn.
If we look at the above class, we can see that no checks are carried out to see whether the block below the dragon egg's teleportation destination is air. The only checks that are in place are to see whether or not its desired teleportation destination is air, and is within the world border. This is evident through the following line of code:
if ($l.getBlockState(blockpos).isAir() && worldborder.isWithinBounds(blockpos))Because of this, dragon eggs can teleport on top of any block.
Can confirm in 22w06a.
Can confirm in 1.18.2.
