In my game there is a word at top of the screen, letters are raining down from top and the user has to touch the letters to complete the word.
Currently I am generating letters randomly (actually random numbers and numbers are the index for the array of letters. e.g: 0=a, 1=b) but the problem is that it takes too much time to get all the required letters to complete the word.
What I want is that the random numbers that I am generating should generate required letters more often so player don't have to spend all day to complete one word.
I have tried following methods:
Detect all the letters in the word (word is always 6 letters long), generate the array of indexes of length 6, assign each index of the array to random number from letter-2 to letter+2 and in the end pick randomly one index from the array to show.
Have a selector variable whose value is in the range [0..2], generated randomly, if selector == 0 then detect letters which make the word and randomly pick one letter, else randomly get any alphabet from a-z.
Both of these methods have not provide me with any help. I will be very happy if you can help me.
Thanks for reading this, I hope you understood the question and I am waiting for the response.
