Hi all, I have a quick question. My game implements a primitive inventory system using the default Playmaker array. When dragging an item, I use the Fake Drag system, that is, the inventory cell is deactivate, and a UI Image ("Dragger") is created in its place, taking a sprite depending on the inventory cell. But I have a question: I want the player to be able to use the mouse to give an item to an NPC. I know that UI can interact with GameObject if it has RigitBody2D and Collider2d on it. But the problem is that the UI is displayed on Canvas, and they can't collide with the gameobject(NPC) on scene. How can I solve this problem? Thanks!
