if your array looks like this
I think this is the simplest way
so... if you set the first answer is always the correct answer
after you randomize question order capx should look similar to this
if you use sprite for answers...basically its the same thing..
just one "spriteAnswer"..write frames in array and set variable correctAnswer to number
EDIT2: ...that is one way.
.if you have specific frames as answers and just want to randomize frames position...
another way is if you want to set one correct frame and three random frames..
you can then use one dimensional array for questions
just be sure your "spriteAnswer" frame 0 is correct answer on first question- Array.At(0),
frame 1 is answer on Array.At(1) etc...
and use another array for frames...
