CETris

• 

  back when a glitch block was in the game. I kept it around for a while for testing, but now it's been patched out.

• 

  Early test of collisions.

• 

  This was part of the 4 hour problem. Do you see what's wrong?

• 

  look at these "interesting" rotations! (early version)

• 

  Sceenshot from the most recent version.

Inspiration

I think the already existing tetris is lacking features. So I tried to see if I could make a better version.

What it does

It's Tetris. Clear lines, get points, try not to top out. (Topping out in this doesn't do anything but get you stuck at a point where all you can do is quit.)

How I built it

Programmed using Notepad++, compiled with spasm

Challenges I ran into

I spent 4 hours trying to figure out why something was crashing ld d,0 had to be ld de,0. That was annoying

Accomplishments that I'm proud of

It works! I'm very happy with the collision system: it works better than I hoped.

What I learned

Check for undefined behavior. I think I could've done much better if I didn't get stuck for so long on a simple fix.

What's next for CETris

Add features, make it more easily customizable. I do have a java program that will convert an image into palette and data for use in this program, but it's not user-friendly and requires some trickery. I might clean that up and add it to project.
