what is the best and easiest way to go about building a 2d memory match game using blueprints, ui and 2d sprites or paper 2d? Please help, unable to find a simple solution for this problem of mine.
I believe your best bet is to use the Unreal Match 3 project that is available in the Epic Launcher the Games category of the Learn Tab:
The description says: “Unreal Match 3 utilizes UE4 features such as the Unreal Motion Graphics (UMG) UI editor and the Paper 2D toolset. With the Unreal Match 3 project, you can look through the game’s Blueprint scripts, art assets, and C++ code, and use the assets for your own projects.”
It may not be exactly what you need, but I think it has many of the elements you may need, and will hopefully be a step in the right direction. Good luck
