Bindables: Reactive Programming

bindables.dev | Documentation | Discord

You can now get Bindables as part of the Flexalon + Proxima + Bindables bundle.

Bindables brings the power of reactive programming to Unity—giving you a clean, declarative way to track game state and automatically reflect changes wherever they’re needed.

With Bindables, you declare your state using Bindable<T>, then declaratively bind that state to any Unity component—like UI text, images, animations, or prefabs. It works seamlessly across UGUI, UI Toolkit, and any other Unity objects.

Reactive by Design: State changes drive everything. You declare your bindings once and they update automatically.

Extension Methods: Bindables generates Bind extension methods to every Unity object (that you want). This makes easy and type-safe to bind to all built-in Unity types, 3rd party packages, and your own components. Materials, images, text, sprites, transforms, you name it.

UI Toolkit and uGUI Support: Works with both UI frameworks in the same way. Declare bindable state and bind it to UI components.

Two-Way Bindings: For input fields, sliders, dropdowns, and toggles, you can bind your state to update automatically on user input.

Advanced Bindings: Derived state, animations, time intervals, file URIs, and more.

FEATURES:

• Bindable: declare reactive state.
• Exension Methods: All Unity components get convenient new .Bind*() methods.
• For example: textmeshpro.BindText(playerName)
• Derived: transform or combine Bindables into new state.
• BindableList: Bind to lists to instantiate prefabs or visual elements.
• BindableDictionary: Bind to dictionaries to instantiate prefabs or visual elements.
• BindableAnimator: Drive animations using easing curves, math, or Unity animation curves.
• Bind to input actions, events, time intervals.
• Bind to file and web URIs to download images and audio clips.
• Automated event handler management with BindContext.
