Unity's New UI System
summary
Unity 4.6 beta introduces a canvas-based system with three render modes (screen overlay, camera, world space), a visual anchor tool nicknamed the power flower, and a content size fitter plus nine-slice and tiled sprites for scalable panels. UI elements pass typed values — sliders send floats to change rotation speed or particle emission, toggles send booleans, buttons call Animator triggers — enabling no-code event hookups. RawImage can show a camera render texture and Mask clips it, and the Graphic Raycaster handles cross‑platform input.
