Pack Making JSON Definitions - DonBruce64/MinecraftTransportSimulator GitHub Wiki

This section only appears on content that requires OBJ models. Vehicles, signs, decor, etc. all have definitions on account of them rendering 3D models. Each entry in this section is simply a variant of a different texture on the same model, with potentially different names and descriptions. If a component uses definitions, then you will need to specify at least one, even if the component only has one variant. Also note that anything that has a definitions section is able to be added to dynamically via a skin. Every definition entry has the following sections:

• hideOnCreativeTab - Set to true to hide this item on creative tabs.
• subName – This text value will be appended to the JSON filename to get the name of the component. This name is then used to tell MTS the name of the texture and item to use when rendering this component. Remember, the subName is APPENDED to the JSON file name. If you name your textures off the sub name MTS will not be able to find them! If you are making a single-variant model you can leave this field empty (""), but it must be present otherwise MTS will crash on load.
• useVehicleTexture – This parameter is optional. If included and set to true, this part will use the texture of the vehicle rather than the texture that corresponds to the part. Useful for parts that need to pull vehicle textures for their rendering, such as tank turrets and vehicle bolt-on components.
• partTones – This parameter is optional, and is only used for vehicles and parts. If set, when the vehicle's color is changed with the paint gun (or when default parts are first placed on it) the new color's definition is checked for partTones. If they are set, all part placement definitions will be checked. If any of them has a toneIndex, it will be matched with one of the tones in this list. If the part has a definition with the tone specified by the number, then it will be switched to that definition.
• constants - Like the constants in the rendering section, except these are for this definition, and will update if the definition changes due to a paint gun operation.
• secondaryTextColors – This parameter is optional. If set, any textObjects marked as colorInherited will use one of the colors in this list rather than their own. The exact color to be used is specified by the textObject. Useful when you have multiple textures for your model that would cause issues with a single text color.
• modelName – This parameter is optional. If set, then the model with this name will be used for this definition rather than the default one. This model must be in the same folder as all other models for this component, but it may be in sub-folders if desired.
• textureName – Like modelName, but used to override the texture. Useful if you have multiple models with the same texture (say different orientations of the same thing).
• name – The name of this component. Will be displayed in item form and in the benches. Note that this is just a display name, and is NOT used in any file-linking operations like subName is, so you can put whatever you want here.
• description – An optional description. This will be appended to the main description if it is present. This allows for dynamic descriptions for different variants.
• extraMaterialLists – Like the materials in the general section, except these are added to the base materials to allow crafting of the variant specified. This is where you can put dyes for color variants to differentiate them from one another. These are also what will show up in the paint gun GUI. Note that the number of lists here must match the number of lists in the materialLists, as each materialList entry is paired with an entry in this variable. Also note that these are not used for repair recipes.
• extraRepairMaterialLists - Like extraMaterialLists, but these materials, in combination with an existing instance of this item, can be used to craft a fresh copy.
• extraReturnedMaterialLists - Like extraMaterialLists, but these materials are dropped after crafting. Think returning a bucket after needing a bucket of water.
