Maybe you could create letter sprites, and assign each one to a key on the keyboard(ent_create them, and move them by code with the player, but this will take a little math, due to the fact that most (if not all) letters are not in the exact center). Or if you want to be fancier, you could use models.
This could get
very tedious, though. You would have to do either
tons of ifs, or one big switch/case statement (wouldn't be much easier) for each key:
Code:
switch(letter)
{
case key_a:
// code goes here
case key_b:
// and here...
case key_c:
// you know what to do.
...
case key_z:
//hooray! you're almost done!
}
