# Panel Raycaster
|
||
|
|
|
||
|
|
A derived [Raycaster](Raycasters.md) to raycast against UI Toolkit panel instances at runtime.
|
||
|
|
|
||
|
|
During the Start method of the EventSystem, a PanelRaycaster is automatically added to the scene 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](script-GraphicRaycaster.md). 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 systems with UI Toolkit,
|
||
|
|
refer to [FAQ for event and input system](https://docs.unity3d.com/Manual/UIE-faq-event-and-input-system.html).
