Hey, really big thanks. Yeah it is made with gamemaker studio 2. I dont have a git for it yet but if you want I can share some of the codes or parts of the project and how things are done with you. I just have not used github with gamemaker before but I can look into it. I could also make video explaining how everything works later when I have time :)
Viewing post in Rock, Paper, Scissors Card Game comments
Can I get your discord? I could send you something there. But I can also tell all the simple things here in comments :). I have one card object and multiple sprites that are randomized. So at first you want your card to have the "back" sprite but when you click/drag/open it you should have something like "if sprite_index = back { sprite_index = choose(rock, paper, scissors);} in click event. And to get that card go to the position where the mouse is just put "x = mouse_x;" and "y = mouse_y;" in mouse down left event.
I also have place where the card goes and that I have done by putting in the collision event with that place "x = place.x" and "y = place.y". But if you would like to have images and files etc I could send them through discord. Just give me your tag and name so I can add you :)
