Three dimensional scenes in Decentraland are based on the Entity-Component model, where everything in a scene is an entity, and each entity can include components that shape its characteristics and functionality.
The rendered shape of an entity is determined by what component it uses.
Use the Scene Editor # The easiest way to give an entity a shape is to use the Scene Editor . You can add a Mesh Renderer component to provide a primitive shape, or a GLTF component to reference a 3D model from a file.

To make a button in your UI, create a Button UI element. The button must have the following:
value: A string with the text to display on the button. It can also have:
onMouseDown: A callback function that runs every time the user pushes the pointer button on the entity. 📔 Note: To click on a UI component, players must first unlock the cursor from the view control. They do this by pressing the right mouse button and keeping it pressed, or by hitting Esc.

For all kinds of UI content, use the uiTransform component to set the size, position, and other properties related to the entity’s alignment.
The uiTransform component works in the screen’s 2d space very much like the Transform component works in the the scene’s 3D space.
import { ReactEcsRenderer } from '@dcl/sdk/react-ecs' ReactEcsRenderer.setUiRenderer(() => ( <UiEntity uiTransform={{ width: '200px', height: '100px', justifyContent: 'center', alignItems: 'center', }} uiBackground={{ color: Color4.Green() }} /> )) Positioning properties # The alignment of UI entities is based on the Flexbox alignment model.

Libraries are a great way to share solutions to common problems. Complex challenges can be approached once, the solutions encapsulated into a library, and whenever they come up you just need to write one line of code. By sharing libraries with the community, we can make the productivity of all creators grow exponentially.
Currently, these libraries in the Examples page are available for all to use. We encourage you to create and share your own as well.

Run multiple Decentraland projects in preview by grouping these into a workspace. Run multiple adjacent scenes to see how they fit, or also run multiple smart wearables together to see how they interact with each other and with different scenes.
Running multiple projects in a workspace provides a much more complete testing alternative, to ensure different content works well together. A workspace is a debugging feature, it doesn’t affect the experience in the published scene.
