That looks really nice!  Great job!

So instead of just changing the grayscale level you're adjusting the contrast?

That's what I mean...instead of doing grayscale you're adjusting contrast to get that look type thing.

Cool.

Looks nice. I used these effects in Illusiat 2004-1, ROL3 (altough mostly fading to white) and Zelda: Dark Link Quest. I believe Reuben Quest also used some, but I don't exactly remember.

Just one thing, though: contrast level is different between the regular 83+, 83+ silver edition, 84+ and 84+SE. On the TI-Nspire, it's the same as the 83+. On the SE it's about two levels darker than 83+ and 84+ even darker. What I suggest is that you use a dynamic default contrast value for when the screen is not faded to black, and let the user choose his default level contrast to play. That way, the game will looks fine on every calc model. Another idea would be a routine to detect the calc model the person is running and have contrast be a few levels darker on the 83+SE than the 84+ and a few more on the 83+, but then on the Nspire, it might be hard.

Anyway I can't wait to see the gameplay in action

oh, that could work, too. It would also be nice if you could post the code you used to change the contrast because I couldn,t find anything in the Axe doc.

ok thanks, but is there one to set contrast to a specific value in particular? With your commands, there's no way to know at which point to stop increasing contrast.

Also make sure that when people are pressing Clear (assuming this is what you'll choose as Exit key, since ON is disabled in Axe programs), the contrast is reset to the original level on their calc so they don't need to set it back to its original value all the time
