A datapack to fix MC-272431.
More basic version of my Old Dragon Mechanics datapack that, though having only one feature and no customizability at all, is very lightweight and supports versions all the way from 19w08b (1.14 snapshot that introduced MC-272431 that hasn't been fixed since) to 1.21.4. While the datapack functions "as intended/expected" on Minecraft versions 1.13 to 19w08a, using it before 19w08b causes the dragon to act very erratically, going uncontrollably up and down for a few seconds until it slows enough to get to the height it wants to be at.
Non-existent.
To change the vertical fly speed of the Ender Dragon, you'll need to modify /data/dragonfix/functions/ai.mcfunction (or /data/dragonfix/function/ai.mcfunction for 1.21+) directly to change it.
I may add configuration in the future (albeit small because this pack has less features, likely only having "Fly Speed" and "Enabled?" as config options), but for now, there's no config.
- Fix MC-272431 on all versions affected by it, from 19w08b to 1.21.4
That's literally it.
