DatapacksJava
Deny Elytra Flight
No elytra flying. Tiny and optimised pack using the new 1.21.2 glider data component to disable elytra flight once equipped.
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
With the new 1.21.2 glider data component, disabling elytra is able to be done cleanly with commands. This tiny datapack is optimised for performance by using a hidden advancement to only modify elytra upon being equipped, instead of checking every tick.
Restoring Elytra (Uninstall Instructions)
Run the following command once you've disabled the datapack to restore all elytra currently worn back to Vanilla behaviour:
/item modify entity @a[nbt={equipment:{chest:{id:"minecraft:elytra"}}}] armor.chest {function: "minecraft:set_components", components: {"minecraft:glider": {}}}
