Dragon Movement Fix

About

Dragon Movement Fix is a Minecraft 1.14 - 1.21.4 datapack to fix MC-272431, a bug introduced in 1.14 snapshot 19w08b where a typo in the Ender Dragon's vertical movement code causes erratic behavior from the Ender Dragon, such as slowly gliding down to perch instead of diving to the central bedrock podium.

If you've ever fought the dragon in an older version like 1.12, you might know what I'm talking about.

Patches out one-cycling and other strategies that rely on MC-272431.

Dependencies

• Fabric API (Fabric/Quilt mod only)
• A newer version of Minecraft (Forge Mod version only, specific required version unknown)

To Modpack Creators:

I permit the use of this datapack/mod in your modpacks. You can include it in modpacks without the need to ask me about it. However, notifying me if it is being included in your modpack would be nice.

Notes

• This datapack isn't perfect, and has some issues related to the dragon's vertical velocity, most of which aren't fixable without heavily altering the pack and causing it to drop support for older versions of Minecraft (there's already Customizable Dragon AI that has a lot of the issues fixed, along with a bunch more features, but only supporting 1.20.3 and newer), for example explosions will cause the dragon to launch 10x as high as it would normally, for one tick only, before going back to a normal-ish amount of knockback.

Trivia

Some fun facts about this project!

• Funny thing, I probably won't ever have to make a change to how the pack works in order to support a version because it doesn't use any commands that Mojang are going to change in a way that breaks the pack in the forseeable future. The only reason this pack would need to be updated is to fix a bug or add something.
• This project was created AFTER my other similar project, Customizable Dragon AI, despite this being uploaded
