[SOLVED] Mouse location to world space

On the Widget you’re dragging, go to the Graph view and next to Functions, click from the Override option the dropdown item called On Mouse Button Down. Then also click On Drag Detected. In On Mouse Button Down, from Mouse Event, drag and create a node called Detect Drag If Pressed. Choose the Left Mouse Button (or whatever button you use to drag and drop!). Now connect the output to the return out.
Now in On Drag Detected, you can drag from the Pointer Event and Get Screen Space Position on the mouse cursor. With a Deproject Screen to World node you could get World Space if you need it. The result can be Promoted to a Variable and then passed on later for whatever other needs you may have for it.

Does this give you the desired functionality you wanted?

So obviously I’m almost 4 years late to this party but I’m doing almost exactly what you are saying but getting the PointerEvent from OnDragCanceled, then using GetLastScreenSpacePosition and feeding it into DeprojectScreentoWorld.

This works perfectly in full screen but if in a windowed mode, like the editor, the trace seems to hit bottom-right to where it should do and not in a consistent offset it seems to be warped.

If i multiply the result of GetLastScreenSpacePosition by GetViewPortSize / GetScreenResolution before plugging it into DeprojectScreentoWorld the offset is different, the trace hitting closer to the center of the viewport than where I stopped dragging, no matter what side of the screen it is dropped. Anyone have any idea what the problem maybe?
