[TI ASM]Need ever shrinking tunnel

I sat down at 11 o'clock to make Copter (horizontal fast tunnel with obstacles and you hold 2nd to ascend and hold nothing to descend). And one hour later, it was working fine (I have a strange obstacle bug that I can work out). However, I am not satisfied with my shrinking-tunnel code. What's a good algorithm (no code) for this? I got good results from giving it a 1/3 chance to grow and a 2/3 chance to shrink, but it shrank to quickly. I upped it to 127/255 chance to grow, and I got some very strange bugs. So I ask you people, what's a good one?

keep the size the same, but move the actual cave up and down. make the size between the top and bottom get slightly smaller every couple of seconds.

I use BrandonW's code with some modifications. Got this:

O_O wow

I tried the game, btw, doesn't it use blocks in the middle too? Being bad at that kind of game, I didn't see how much it narrows.

hmm, could you make the ball a little less reactive? It seems to jerk up and down a little too much and too fast, IMHO. Nice job though, it looks good, other than that.

That screenshot doesn't show how the ball really works. Don't worry. Yeah, there will be blocks. The block code is broken. And it is a helicopter now.

It looks good to me. Of course, you need to have a limit on just how small it can get, otherwise the tunnel might just close. Nice work.

yeah, a limit is important. On the original falldown, the lines would get too close together and you could not keep going. Later versions fixed this.

So, any more screenies? maybe with the helicopter?

Maxes out 24 on both sides so 16 pixels of space to get through. The copter is only 4 pixels tall, so you're good.
