World Space UI is a powerful way to display interactive elements in a 3D scene, and in this video, we explore how to create it using UI Toolkit in Unity. We demonstrate a practical implementation with a Damage Numbers spawner, building a reusable WorldSpaceUIDocument class that renders UI Toolkit elements onto a RenderTexture. This allows for floating UI elements that integrate seamlessly into world space. The system leverages Unity Object Pooling for efficient instantiation and performance, and we discuss key considerations like shader selection, panel scaling, and rendering optimizations. By the end, you'll have a solid understanding of how we can use UI Toolkit in world space.
