JsonEM (Json Entity Models)

Library for modders, resource pack makers, and modpack makers to create and edit entity models WITH JSON
Does not work with OptiFine format!

Generate Vanilla/Mods' Entity Models:

If you'd like to dump json-ified versions of all entity models (vanilla or modded) so that you can edit them easily with resource packs or use them as examples, here's how:

• Launch the game, and then open the configuration file located at .minecraft/config/jsonem.properties.
• Edit the second line of the file to be dump_models=true.
• Re-launch the game. Navigate to the folder .minecraft/jsonem_dump.
• Within this folder you should find all registered entity models dumped as json, formatted like a resource pack.
• Use this format when editing or adding models with a resource pack.

For Resource Pack/Modpack Makers:

• Complete the steps above to dump all entity models from your game or modpack.
• When editing your resource pack/modpack resources, add entity model json files as they are formatted in the dumped model folder.

For Modders:

JsonEM can be used to create TexturedModelData for your entities entirely using json.
This guide will demonstrate how to make the model for the cube entity in this tutorial with json.

• Include the mod as follows:

TBD

• Register the entity model layer for your entity through JsonEM instead of Fabric API (Excludes the need for a code-generated TexturedModelData)

void onInitializeClient() {
    [...]
    JsonEM.registerModelLayer(MODEL_CUBE_LAYER);
}

• Add a model file to your mod resources containing your entity's model data
  EX: assets/my_mod/models/entity/my_entity/layer.json

{
    "texture": {
        "width": 64,
        "height": 64
    },
    "bones": {
        "cube": {
            "transform": {
                "origin": [0, 0, 0]
            },
            "cuboids": [
                {
                    "uv": [0, 0],
                    "offset": [-6, 12, -6],
                    "dimensions": [12, 12, 12]
                }
            ]
        }
    }
}

• Make sure that the bone "cube" in the file above is being accessed with the same name in your entity model

public CubeEntityModel(ModelPart modelPart) {
    this.base = modelPart.getChild("cube"); // The original tutorial used an unspecified field called EntityModelPartNames.CUBE
}
