This repository contains all of the smart itmes that are available by default in the Decentraland Builder.
Smart items are special assets that include custom functionality, like buttons that can be pressed or doors that can be opened. Learn more about them in the Builder documentation: docs.decentraland.org/builder/smart-items/
To create your own smart item, it's best to copy one of the existing smart items in this repository and edit it. The main files in a smart item are:
asset.json: The smart item manifest. Includes name, ID, category, tags. It also defines all the configurable parameters available in the UI, and all the actions that can be called by other smart items that share a scene.
item.ts: Contains the main code that controls the behavior of the item. Must include a class definition for the item, that has an init() function (to be called once when the scene starts), and a spawn() function (to be called once for every instance of the item when initialized). The spawn() function must take an argument of type Props that contains all of the parameters configured in the smart item's UI.
game.ts: Contains a scene that is used for testing the item's functionality locally. This scene can include multiple instances of the item, or other entities to carry out more elaborate tests.
