example of what i am trying to do: i have a string that = "random" and i want to get just the 2nd letter in this string which in this particular scenario it is "a". How do i do this? Best in a for loop as i need to be able to go through every single letter and find/use each letter/number.

Create a GreenfootImage equal in width to the sum of the two images and draw the individual images on that new image at the appropriate locations. You can continue adding more letters in the same way using the last image created and the new letter image to add (create an image equal to the sum of the width of both of these and draw the images on the new image again).

The first image is drawn at (0, 0), the new letter image is drawn at (first image width, 0).
