Data binding connects data stored in View Models to properties in your Rive scene. When data changes, your scene updates automatically. Likewise, changes made in your scene can be written back to your data. For example, you might:
  • Bind an enemy’s X and Y position so it can be controlled at runtime.
  • Bind the color of multiple icons to a single color property.
  • Bind a health value to a health bar in the UI and to the character.
  • Swap images, artboards, or components based on your application’s state.

​
Why Use Data Binding?

Data binding lets you organize your data independently from your scene hierarchy. For example, you might have a health property stored at the top level of your data, while the health bar that displays it is nested several layers deep inside components. Once the property is bound, the hierarchy no longer matters. You can move elements, reorganize components, or rename properties without rewriting runtime code.

Core Concepts

  1. View Models define the structure of your data.
  2. View Model Instances store actual values for that data.
  3. Bindings connect View Model data to properties in your scene.
  4. Data can be updated from the Editor, runtime code, state machines, or scripting.
  5. When data changes, bound elements automatically update to reflect the new values.
