MVVM-style data-binding system for Unity.

Unity-Weld is a library for Unity 5+ that enables two-way data binding between Unity UI widgets and game/business logic code. This reduces boiler-plate code that would otherwise be necessary for things like updating the UI when a property changes, removes the need for messy links between objects in the scene that can be broken easily, and allows easier unit testing of code by providing a layer of abstraction between the UI and your core logic code.

A series of articles on Unity Weld has been published on What Could Possibly Go Wrong.

Example Unity project can be found here:


To install Unity-Weld in a new or existing Unity project:

  • Load Unity-Weld.sln in Visual Studio and build it
  • Copy UnityWeld.dll into your Unity project and place in any directory within Assets
  • Copy UnityWeld_Editor.dll into your Unity project and place it inside an Editor folder within Assets

Alternatively, just copy the UnityWeld/Binding and UnityWeld/Widgets folders into your Assets directory in your Unity project, and copy all the .cs files in UnityWeld_Editor to a folder named Editor inside your Assets directory.
