IPointerDownHandler on GameObject behind the UI element with IdragHandler ?
Hello everyone. I have All_over_screen UI element with:
public void OnDrag(PointerEventData eventData) {
//code
}
now i want to interact with 3d objects on the scene with EventSystems:
IPointerDownHandler,
IPointerUpHandler,
IDragHandler,
IEndDragHandler,
IBeginDragHandler
I put PhysicsRaycaster on camera and interaction script on GameObjects i want to interact with:
public class Interactable : MonoBehaviour,
IPointerDownHandler,
IPointerUpHandler,
IBeginDragHandler,
IDragHandler
{
public void OnBeginDrag(PointerEventData eventData) {
Debug.Log($"OnBeginDrag on {name}");
}
//...the rest of debug implementations
}
I also put CanvasGroup on All_over_screen UI to be able canvasGroup.blocksRaycasts = false; and trying to:
public void OnPointerDown(PointerEventData eventData)
{
_canvasGroup.blocksRaycasts = false;
}
But the issue is I don't catch on the Game Object on scene:
public void OnPointerDown(PointerEventData eventData)
{
Debug.Log($"OnPointerDown on {name}");
}
sho the question is - how to pass through the UI element to the game object to catch OnPointerDown event on the object and if not cathed, proseed with OnDrag on the UI?
You can't reach the object behind the UI in 3D scene. Please note, even if there is a transparent ui element which is marked as raycast target, it will receive event and won't let you interact with objects in the scene. For example, if you have a background image on your canvas, even if it's 100% transparent, toggle off raycast target in Image component.
