The New UI System Deconstructed
summary
Unity’s new UI tools are a ground-up rewrite — three years of work, everything restarted two years ago — that pairs canvas batching in C++ with an extendable C# layer, ships under the MIT open source license, and aims to be garbage-generation free to avoid GC hitches. It provides rect transforms, layout groups, raycasters, input modules (demoed with an FPS camera module and a world‑space keypad), an interface‑based event system replacing sendMessage, and a canvas scaler that preserves text across resolutions.
