I’ve created a Drag and Droppable menu item like Wes Bunn showed us in his training stream, but when I drag the item, it disappears from view. Additionally, when I let go and it reappears again at my cursor, it becomes uninteractable. Its buttons don’t generate hover over events anymore, I can’t drag it anymore and for all intents and purposes, it seems like it’s become ‘just a visual’.
I can tell that it is actually the same widget that was first dragged that is also dropped, because all checkboxes on it remain in the state they were in as the new widget appears on screen after dropping.
The interactivity problem has been solved. When creating my HUD, I specified its Z-order in the viewport to be higher than the Z-order of my draggable menu widget. This meant that it was ‘in the way’ of the menu item’s ability to receive hit tests.
However, I still don’t know why my draggable menu item won’t produce a visual, even though I hooked up its “default drag visual” in the create Drag and Drop operation node to a reference of itself, like Wes shows us in the training video.
If anyone could care to answer why that may be the case, that’d be great.
