A derived Raycaster to raycast against UI(User Interface) Allows a user to interact with your application. Unity currently supports three UI systems. More info
See in Glossary Toolkit panel instances at runtime.
During the Start method of the EventSystem, a PanelRaycaster is automatically added to the sceneA Scene contains the environments and menus of your game. Think of each unique Scene file as a unique level. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. More info
See in Glossary for each
active UI Document in the scene. To disable this behavior, call
EventSystem.SetUITookitEventSystemOverride before the Start method
executes.
You can use the Sort Order of the Panel Settings asset referenced by each document to configure the priority of the raycast between multiple documents. You can also use the PanelRaycaster in combination with a GraphicRaycaster. In that case, the Sort Order of documents is compared to the Sort Order of Canvases to determine overall priority.
For additional information about using input and event systemsA way of sending events to objects in the application based on input, be it keyboard, mouse, touch, or custom input. The Event System consists of a few components that work together to send events. More info
