ElytraSwap

A mod that lets you replace the Elytra found in End Ship item frames with any other item... vanilla or modded.

Similar to mods/datapacks like "No Elytra" or "Remove Elytra", but better ;)

Features

• Replaces the Elytra generated in End Ship item frames with a configurable item
• Works in both singleplayer and on servers. When used on a server, no client-side mod is required for players to join

Dependencies

• NeoForge 1.21.248

Configuration

On first launch, ElytraSwap generates config/elytraswap-common.toml:

#- The item to place in the End Ship item frame instead of an Elytra (default: 'minecraft:diamond_block')
replacementItem = "minecraft:diamond_block"

Change replacementItem to any valid item id, then restart the server (or use /reload where applicable) for the change to take effect on newly generated End Ships.

Note: existing, already-generated End Ships won't retroactively change. This only affects ships generated after the config is set.

Updating crafting recipes

Changing replacementItem swaps what appears in the item frame, but it does not automatically update crafting recipes in other mods that require an Elytra as an ingredient. Since every mod defines its recipes differently, ElytraSwap doesn't try to rewrite them automatically - instead, you can override any specific recipe yourself with a small datapack.

Datapack overrides work because Minecraft resolves resources by their full path (namespace:path): if a datapack defines a file at the exact same location as one already provided by a mod, the datapack's version wins. This lets you replace just the recipe you care about without touching anything else.

Example: replacing an Elytra ingredient in another mod's recipe

Suppose another mod (somemod) has a recipe at data/somemod/recipe/some_recipe.json that requires minecraft:elytra. Create a datapack like this in your world's datapacks folder:

world/datapacks/elytraswap_compat/
├── pack.mcmeta
└── data/
    └── somemod/
        └── recipe/
            └── some_recipe.json

pack.mcmeta:

{
  "pack": {
    "pack_format": 48,
    "description": "ElytraSwap recipe compatibility overrides"
  }
}

some_recipe.json — copy the original recipe file from the mod's jar, then simply replace the minecraft:elytra entry with your configured replacement item, e.g.:

{
  "item": "minecraft:diamond_block"
}

Enable the datapack with /reload (on an existing world) or by starting a new world — check it's active with /datapack list.
