I am working on a game in which we control a rectangular box at the bottom of the screen. Three sphere which has alphabets in it fall down. When the game starts, a word is generated from the predefined list of words(which I'll give) and we are supposed to touch the correct sphere having the alphabet based on that word. The question is how to detect if I have touched the correct sphere. secondly, if I have touched a correct sphere before and there is no recurrence of that alphabet in that word then during the second wave the game should not proceed if I touch the same alphabet again. Looking forward to your answers, i have to submit this project in a couple of days. please help! (Working on Unity 3D) Thanks
