I’m interest in doing the same concept but not math related. I’ve been “Dividing and conquering” since there isn’t any tutorial on how exactly to do a game like this from start to finish on Unreal. The only part I’ve been having major issue with is the Collision and Expression aspect. I have conquered the infinite runner formula of endlessly having the floors adding and destroying in a loop (You actually helped me with that a couple months back - How to Fix the Infinite Loop Detected). I learned how to do Trivia style games in blue print and logging correct or wrong answers using mouse clicks, I believe when I get to the part about enemy interactions I’ll overcome it given I’m learning about AI and player pawn interactions in a Udemy course. But how do you go about using a collision to interact with the correct or wrong answer and log it? Like the “Expression oracle” aspect of the Fat Dino’s video (Time code - I Turned Fake Mobile Game Ad into a Real Game - YouTube) which was actually what inspired me to start it even though I was sitting on the idea for a while but was new to game dev. Is their any documentation or tutorial on this aspect alone. It’s the only part I have not been able to wrap my head around to get done. Especially attaching the widget to the actor and still have it randomize the options in the question array. Any advice or guidance will be greatly appreciated.
