How to Add the Data Pack to an Existing World
You do not need to start a brand-new world to begin crafting elytras. The pack is designed for balanced integration into worlds that are already in progress.
Placing the Pack in Your World Folder
To apply the recipe to an existing single-player world:
1. Select your world in the Minecraft title screen and click Edit, then select Open World Folder.
2. Open the datapacks folder located inside your world directory.
3. Place the data pack file directly into this datapacks folder.
4. Return to Minecraft and load into your world.
Enabling and Verifying the Recipe
Once inside the world, make sure the recipe is recognized by the game engine:
1. Open the chat window and run the command /datapack list to verify that the pack is loaded and enabled.
2. If the pack appears disabled, run /datapack enable "file/..." choosing the pack name from the autocomplete suggestions.
3. Type /reload to reload all data pack functions and recipes.
4. Open a crafting table to ensure the elytra crafting recipe appears in your crafting options.
