Okay, it's now fully playable.



Rules

Like the original game, each card has four properties (number, color, shape, pattern). A "set" is a group of three cards in which every one of the properties is either the same or different. (but not two cards alike with only the third different).

Twelve cards (or more if needed) are laid out and you have to try finding a set. When you find one, you press [Graph] to call it, and then select the three cards. You get a point and those cards are replaced. Calling "set" incorrectly causes you to lose a point. (Though you can disable this penalty in the settings.)

If you wait to long then the calculator will "find" a set first and get a point. This time is defaulted to about 20 seconds (on the 15mHz calcs at least), but you can adjust it in the settings for an easier/harder game.

Controls

Arrow keys - move cursor around
Graph - Call a set
Graph/2nd/Enter - Select cards (after calling a set)
2nd/Enter - Deal new cards (after the calculator calls a set)
Trace - Enter/Exit the settings menu
Clear - Exit

Doing a zoom compile with the °GIT set to 1 throws an ERROR: Undocumented on the "performs magic" line of GreyLib.

Why is this?

Wow, 4 years since the initial post. :O Are you finishing this or are you working on anything programming related at the moment?

I just picked it up again to try finishing it, but not sure if I'll be able to complete it.

The problem with using interrupts for greyscale is that they update the display before I'm finished drawing to the buffers. If I turn off interrupts during the drawing routines than there's a noticeable lag where the greyscale freezes into monochrome.

My usual method was to have all of the drawing commands followed by dispgraphclrdraw^rr in a single loop.

Other than creating a 1,536 byte buffer in the ram, the only thing that I can think of is to rewrite all of the drawing routines to only erase each section right before it gets redrawn instead of constantly clrdraw'ing everything at once.

I am porting the card game set to the 83/84 plus calculators in axe.

So far I did close to everything besides for the Human element. (I did the AI)

here's a screenshot:



Edit: Here's the above screenshot but with the frozen frames removed. As per suggestion from Sorunome I had switched over to managing the greyscale via interrupts, and so this image more closely resembles the game as it was before I abandoned it.
