nvm.
Disp' sets the buffer for grey part of the screen, iirc.
so after that, do Disp whatever and pxl test.

Yeah.... But gray (50% gray) is a checkerboard design, so wouldn't it half the time see pixels as off because half the time they are off?

Better idea:
You will have a pointer to the gray layer (you have to define it anyways). The buffer will not change, regardless of the checkerpattern (that is only factored in when actually displaying). So if Z points to the gray buffer, you can do this:
pxl-Test(Y,X,Z

The extra argument "Z" makes it read from the buffer at Z instead of the black buffer. Does this help any?

Soooo, nxtboy. The "Mindstorms Nxt" in your sig... LEGO Mindstorms? The thing I've wanted since I was in 2nd grade (9 years, for the record)? That one? The one I'm super jealous about? That one? :P

I completely forgot to give a heads up, but I have spring break starting about a half hour ago. My internet access will be a bit limited, so updates will not be here for a little while. Maybe I might get some more cool stuff done XD Then again, I have a few tons of homework to muddle through :/

About the platformer games....
Doesn't that mean that you can only have 2 types of blocks, solid and not solid? There cannot be blocks that kill you, blocks that are breakable, etc.?

Yes... But how would that be done?

EDIT: Because since it uses pxl-test it can only check if a pixel is black/white.

What I did before is that display tilemap, and get the tile number based on the coordinate. If that tile number matches certain number, you die or something.

So is it impossible using pxl-test and not a tilemap? How would it be done?

you can mix with the pxl-test if you want to.
Let's say you have a appvar with tilemap stuffs.

So you can do X/8 and Y/8 (x and y being coordinate) to get which tile goes where. And you can do a little math to figure out the location of the appvar (aka tile number).
And you can test with both pxl-test and tilemap number.
