Can I make a drop operation on a Blueprint Actor?

Can I drop an item on a blueprint that is in my world? From slot, to Actor, with mesh and everything. And can I run a trace on drag so it can detect the 3d object?

Under normal circumstances cursor position is not sent to the Player Controller during a drag & drop operation. You’d need this to line trace / get object under cursor. You could have other objects have invisible widgets but that’s messy.


It’s undocumented but if you look closely at an extended Drag & Drop operation, you’ll see that it has an overridable Dragged which will report mouse position which can be used to project mouse screen space to world space.
