Greetings. I’m trying to implement basic inventory functionality using 3D widget to display all information regarding it.
I trapped into situation when trying to start Drag and Drop opetation and it fails on drop. It looks like just after start dragging WidgetInteractionComponent seems to stop responding on mouse movement until i drop object i’m dragging.
If i switch to InGameUI widget, which is 2D widget within my HUD, and then trying to drop item, it shootds onDrop event else it just skipping this event.
Summary : I cant procced with OnDrop event when trying to drag object into 3D widget.
Unsupported at this time, it will require Slate provide a means for custom drag / drop handling that subverts the normal process of ceasing normal input flow while dragging, and instead let some other entity control the dragging and dropping. In a way that doesn’t involve the standard cursor input, which also means it must continue to send all normal input, even though a drag drop is occurring in a way it is unaware of.
It looks like 3D widget component doesn’t support ButtonUp event at all…
As for drag-n-drop: while pressing any button add relative location of mouse axis X Y to widget component Y Z.
“at this time” means we will be able to use drag and drop operation on 3D widget soon or maybe never?
VR games are common now (Steam, GearVR, Daydream, etc) and can only use 3D widgets, this should be on top of the list of priority
