Elytra Tuning

# Elytra Tuning A lightweight mod that adds configuration options to **limit** elytra flight speed and **change** firework boost **strength** and **duration**. Works in both **singleplayer** and **multiplayer**, with an optional client-side mod that offers additional improvements for players. > Ideal for multiplayer servers that want to **nerf elytra rushing**, **reduce chunk-loading lag**, or **buff late-game travel**. ## Why Use This Mod? 1. **Configurable Speed Limits**: Limit either horizontal flight speed or total three-dimensional velocity. 2. **Firework Tuning**: Adjust both the strength and duration of firework boosts. 3. **Impenetrable**: The server syncs the velocity changes to each player, ensuring all experience the same limits or buffs. 4. **Compatible**: Handles normal flight, firework boosting, riptide launches, and modded flight setups such as **Do a Barrel Roll**. ## How It Works Minecraft calculates elytra flight **server-side**, while the client predicts motion **locally**. To apply the configured speed limits and firework tuning: - **Server Side**: Enforces the configured speed limits and adjusts firework boost strength and duration. - **Client Side (optional)**: Mirrors these settings locally to keep flight prediction consistent. > **Note**: > Without the mod on the client, players might experience visual stutter or lag back because their local speed and firework prediction can differ from the server. ## Configuration A config file is created at: ```sh ./config/elytra-tuning.json ``` Default contents: ```json { "speed": { "max": 60.0, "calculation": "HORIZONTAL" }, "rocket": { "strength": 1.0, "duration": 1.0 } } ``` - `speed` - `max`: Maximum allowed elytra speed in **blocks per second**. - `calculation`: `HORIZONTAL` measures `X/Z` movement; `ABSOLUTE` measures total `X/Y/Z` velocity. - `rocket` - `strength`: `0.0` disables acceleration, `1.0` is vanilla strength, and higher values add stronger forward acceleration. - `duration`: `1.0` is vanilla duration, `0.5` halves it, and `2.0` doubles it. - Set `speed` or `rocket` to `null` to not apply any tuning. - After editing, **restart the server/game** to apply changes. ## Showcase ### Speed Limiting **Configuration** ```json { "speed": { "max": 10.0, "calculation": "HORIZONTAL" }, "rocket": null } ``` > **Rocket Boosting**: Measured in-game speed is 9.90 blocks per second. > > !(https://cdn.modrinth.com/data/tkz5oxRZ/images/f7c0dbb379c7f9973bc91eb7e5cf586298b7177a.png) > **Riptide Trident**: Measured in-game speed is 9.99 blocks per second. > > !(https://cdn.modrinth.com/data/tkz5oxRZ/images/55fb16c72ca67412b81819cc89c75ea6a6b7045a.png) ### Firework Tuning **Configuration** ```json { "speed": null, "rocket": { "strength": 8.0, "duration": 2.0 } } ``` > **Rocket Boosting:** Measured in-game speed is 60.65 blocks per second. > > !(https://cdn.modrinth.com/data/tkz5oxRZ/images/90502b9dfa89cce6c040a8261f488b820230ba20.png) ## Contributing & Issues I warmly welcome: - Bug reports - Feature requests - Pull requests Please open issues or PRs on (https://github.com/nwrenger/elytra-tuning/issues). ## License This project is licensed under the **LGPLv3 License**.
