I'd like to make some typing games. Going by tutorials I've found, I think I could make games similar to: Police Quest, Ninja Flu, Zork, the Trilby games, and probably more games that include text and/or use a text-typing interface. That aspect of it doesn't seem too difficult. Nor does it seem too difficult to track typing errors or speed. What I'm having trouble with is maybe the simplest part...or just obscure...
In a basic typing test, you have a block of text on-screen and a cursor. The cursor shows you what letter you have to type next. There would also be some visual indicator of errors, such as a letter changing color. (Example.) How do I build that kind of text interaction into a Flash game?
And (important): How do I do it efficiently, so that I can add or replace text with little-to-no work?
Also: How would I change the "active field" (my made-up term) as in Typing of the Dead or Typer Shark, games where there are multiple words on-screen and typing the first letter of one of them locks the player into that word?
Those are my specific problems. I don't expect to get all the answers here. If you could point me to tutorials or Flash game examples, though, that would help.
