Hey guys,

So, basically, what the title + subtitle says. I just thought it was cool to have a game with a fully-rendered 3D tunnel in it. I have the tunnel, now if you have ideas of a game to put it in, please let me know. ;D



It's pure Axe (excepting some Asm(CB3D) to fasten /2), exactly 2000 bytes, the way it's coded allows for custom deformation of the tunnel (for now, each segment has X = cos(timer), Y = sin(timer)), it's endless, it runs at 9 FPS at 6 MHz and it doesn't use GLib.

Any idea to share ?

EDIT : Frostion suggested http://armorgames.com/play/10289/vector-rush .

My suggestion is a Starfox64-like.

In a tunnel ? And enemies would slow down the game too much I think.

Hmm... I guess that wasn't well thought through.

I don't know, then.

Hidden surface removal should be pretty easy to implement.

Actually no, because of the way I defines faces. To be precise, only 10 vertices are displayed at a time, and 0 faces. I have a vertex at the center of each vertical segment, and each segment has a width (on the X axis) and height (on the Y axis), this way I do minimum calculations.

I was thinking that after you draw the nearest rectangle, that is the clipping rectangle for the next one, and you keep on shrinking it.

But I can't do that since I don't draw rectangles at all ... I only connect the vertices of two segments and the vertices of a single segments with a clipped line.

But you know the position of the four vertices that make a segment?
These are the edges of your clipping rectangle.

That looks so cool  *.* did you use #ExprOn? That could speed it up. I always forget to use that in my games...

This looks a lot like what ben_g did here. Was it made on purpose to compare your performances with GLib again ?

Sorry if I answer with something that seems unrelated, English is not my primary language and I might not have understood well. Sorry if I make English mistakes too.

look great  :D . The only thing who surprise me is that you have only 10 vertices displayed, and that it doesn't run so fast ...  :P   :troll:
An other thing : can't you check the sign of thing like X2-X1 to see if face need to be remove or not ?

More on that below.

That looks so cool  *.* did you use #ExprOn? That could speed it up. I always forget to use that in my games...
Yeah actually I forgot to add that :P but it would have been over 2000 bytes then.
This looks a lot like what ben_g did here. Was it made on purpose to compare your performances with GLib again ?
It was made on-purpose, but not to compare perfomances. I just loved the game ben_g showed, and wanted to make one similar but more advanced :)

An other thing : can't you check the sign of thing like X2-X1 to see if face need to be remove or not ?
I draw 116 lines. That's why it's not so fast.

Mh yeah actually I could discard a segment if its leftmost X is smaller than the leftmost X of any nearer segment, and same for other vertices. Since my vertices are already ordered from nearest to furthest, that'll be simple. The only downside is that since the culling does not depend on the camera, you must stay inside the tunnel to see things correctly. In the final game, you won't be supposed to go outside of it anyway :P

Do it  8) I got tons of room on my calc.

Looks quite nice and smooth. I think just a tunnel clone would be fine, but maybe with some power ups that you must take or avoid that can speed you up or slow you down. One main challenge of a 3D Tunnel is that you have to avoid walls on 4 sides rather than just 2, so you have to be more careful.
