# JsonEM (Json Entity Models)<\/p>\n
Library for **modders**, **resource pack makers**, and **modpack makers** to create and edit entity models **WITH JSON**
\n*Does not work with OptiFine format!*<\/p>\n
### Generate Reference Entity Models:
\nIf you’d like to dump json 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:
\n
\n– Launch the game, and then open the configuration file located at `.minecraft\/config\/jsonem.properties`.
\n– Edit the second line of the file to be `dump_models=true`.
\n– Re-launch the game. Navigate to the folder `.minecraft\/jsonem_dump`.
\n– Within this folder you should find all registered entity models dumped as json, formatted like a resource pack.
\n– Use this format when editing or adding models with a resource pack.<\/p>\n
### Edit Models in Blockbench:
\nTo edit models in Blockbench, install the plugin located in this repository.
\n– Download the file `jsonem_models.js` from this GitHub repository
\n– In Blockbench, navigate to `File > Plugins`, and at the top of the dialog click the icon for `Load Plugin from File`. Choose the `jsonem_models.js` file.
\n– Navigate to `File > New` and choose `JsonEM Java Entity Model` to begin editing.
\n– You can also `File > Open Model` to import a JsonEM json model file, such as those dumped from the game.
\n– To **export** your model for use with JsonEM, navigate to `File > Export > Export JsonEM Java Entity Model` and save the file.<\/p>\n
### For Resource Pack\/Modpack Makers:
\n– Complete the steps above to dump all entity models from your game or modpack.
\n– When editing your resource pack\/modpack resources, add entity model json files as they are formatted in the dumped model folder.<\/p>\n

\nJsonEM can be used to create TexturedModelData for your entities entirely using json.
\nThis guide will demonstrate how to make the model for the **cube entity** in **this tutorial** with json.
\n– Include the mod as follows (versions can be found here):
\n“`gradle
\nrepositories {
\n\tmaven { url “https:\/\/api.modrinth.com\/maven” }
\n}
\ndependencies {
\n \/\/ Replace
\n modImplementation “maven.modrinth:jsonem:
\n include “maven.modrinth:jsonem:
\n}
\n“`
\n– Register the entity model layer for your entity through JsonEM instead of Fabric API (Excludes the need for a code-generated TexturedModelData)
\n“`java
\nvoid onInitializeClient() {
\n […]
\n JsonEM.registerModelLayer(MODEL_CUBE_LAYER); \/\/ Layer ID: “entitytesting:cube”, Layer name: “main”
\n}
\n“`
\n– Add a model file to your mod resources containing your entity’s model data
\n**EX:** `assets\/entitytesting\/models\/entity\/cube\/main.json`
\n“`json
\n{
\n “texture”: {
\n “width”: 64,
\n “height”: 64
\n },
\n “bones”: {
\n “cube”: {
\n “transform”: {
\n “origin”: [0, 0, 0]
\n },
\n “cuboids”: [
\n {
\n “uv”: [0, 0],
\n “offset”: [-6, 12, -6],
\n “dimensions”: [12, 12, 12]
\n }
\n ]
\n }
\n }
\n}
\n“`
\n– Make sure that the bone `”cube”` in the file above is being accessed with the same name in your entity model
\n“`java
\npublic CubeEntityModel(ModelPart modelPart) {
\n this.base = modelPart.getChild(“cube”); \/\/ The original tutorial used an unspecified field called EntityModelPartNames.CUBE
\n}
