I've recently finished a tutorial, UE4 Slide Puzzle by Nicholas Thompson. Halfway through the second tutorial, I found out that the blocks / tiles wouldn't respond to my clicks. For example, when I clicked on a tile, it wouldn't print out a Hello message.
I have watched the tutorial so many times already, I've searched it up, looked at my code thoroughly, and I can't find any problems. Here are my blueprints:
After some debugging, I found out that the problem occured at the start of the function, Mesh Clicked in the Event Graph.
Please help, it would be greatly appreciated. Thank you!
