GraphicRaycaster with Camera Space UI

Questions & Answers
1

I am trying to use the graphics raycaster, which operates on window space if I’m not mistaken, with a camera space UI so I can use the UI with a render texture. I already tried using 2D colliders on the UI but that doesn’t handle overlapping very well.
I am now asking for help, because my small brain just can’t figure out how to make a GraphicRaycaster work with camera space UI. My code (actually just unity’s example code modified) works fine with screen space UI if anyone is wondering.

Here are the important parts of the code:

m_PointerEventData = new PointerEventData(m_EventSystem);
m_PointerEventData.position = new Vector2(mouse.simCursorPos.x, mouse.simCursorPos.y);

List<RaycastResult> results = new List<RaycastResult>();
m_Raycaster.Raycast(m_PointerEventData, results);

Vector3 scPos = Camera.main.ScreenToWorldPoint(new Vector3(Input.mousePosition.x, Input.mousePosition.y, mouseCanvasDepth));
simCursorPos = new Vector2(scPos.x, scPos.y);

Thanks in advance

Here’s the solution:

m_PointerEventData = new PointerEventData(m_EventSystem);

Vector2 cursorRaycasterPoint = new Vector2(
(mouse.simCursorPos.x / mouse.cursorCanvas.transform.localScale.x) + mouse.currentRes.x / 2 ,
(mouse.simCursorPos.y / mouse.cursorCanvas.transform.localScale.y) + mouse.currentRes.y / 2 );

m_PointerEventData.position = cursorRaycasterPoint;
List<RaycastResult> results = new List<RaycastResult>();
m_Raycaster.Raycast(m_PointerEventData, results);
