To learn code better I have been taking what I learn from the course content and challenging myself with something different using similar concepts.
So after the Text 101 segment of the course I challenged myself to make a simple multiple choice math question game that generates random integers with 4 questions. Addition, subtraction, multiplication, and division. And there are two answer choices. One being the write answer, the other being incorrect. I tried creating it using scriptable objects but i could not conceptualize it properly with that method so i decided to just do it without “states” or scriptable objects. Now what I’m struggling with is that I cant seem to have the variables that I generate from a function be called out in void Update() which is where i have if statements for the input of the answer. This is my code. Any help or advise is greatly appreciated! <3
