Hero's Elytra Optimizer
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.
4.5.0 Edit
/h-ely debug
- Enables debug messages
/h-ely open
- Opens the config
/h-ely save
- Reloads the config (unnecessary unless edited with the open command)
/h-ely glide [off/delayed/on]
- Sets the per-server state of the glide-stopping optimization
/h-ely rocket [off/delayed/on]
- Sets the per-server state of the rocket-boost optimization
/h-ely pivot [0.0<=input<1.8)
- Adjusts the pivot point
/h-ely offset [0.0<=input<0.6)
- Adjusts the vertical offset
/h-ely instaGlide
- Removes going into the glide animation (from standing to glide animation)
What does it do?
- Optimization that fixes a long standing bug where your elytra being taken off doesnt make you stop flying
Is this allowed?
- Allowed nearly everywhere but please ask before using on any servers that aren't on this list or haven't explicitly allowed it.
How to use?
- Plop into your minecraft mod folder
- Make sure to have fabric api
Compatibility
- Should work with any mods that don't edit an elytra's functionality. Might have problems with modded items that allow a player to fly since it won't let you glide without wearing an elytra.
