I don't think so, because the shape of the track doesn't seem to fit for a tilemap - it has too many curves and stuffs.
And for collision, I noticed that a colour that was in a certain part of the map (by part, understand the road, the plasma balls on each side etc) was not in any other. So to make collision detection, I can just test the area of the ship and see if it contains a certain colour or not. And I still can use the 4-bits identifier of the pixel to detect collision - faster than accessing the scren.

@squidgetx in the screenshot I draw pixels 2 by 2, because drawing each pixel make the game so slow that it's unplayable (yeah DJ_O, 4 times slower). For now I use a giant raw bitmap as a map, because I can just pick up a pixel and display it - the color has the exact good format. What I planned is to encode each pixel of the map with 4 bits (instead of 3 bytes with the actual map). The main idea is that a pixel can either be a colour or a pixel of a texture. This difference is set using the actual value of the pixel. What I planned is : If the 4-bits value of the pixel is lesser than 4, fill it with the corresponding colour of a 4 colours-palette.
If it's from 4 to 15 inclusive, then display it as a pixel of the corresponding texture loaded from a 12 textures array.This should divide the size of the maps at least by 6 - and the original SNES Mute City map will still be more than 2Mb

Can't download it, can you attach it to a post ?

Thanks for that  Do you think you'll port SDL_Image to Nspire someday ? It would be really, really useful to load various image formats

Well, I let people who have an Nspire test  (I can't have mine, so I'll test my game a few months later) Also, big update ! Camera placement is now resolved, the ship is at the origin - this result in a much better gameplay. I drew a sample map to test the engine (and be sure that it works), and I made the movements smooth, like if you actually were in the ship I don't have collisions at all, so you can make your way outside the map - but I don't think it's safe for your calc ... See the first post for the screenshot  Downloads of the current version : Executable and sample map (beware, this latest is 1MB, I really need to implement PNG reading).

And why not "how to build one"

It was the only texture I could think of at this moment but don't worry, there will be better tracks than this one

Are you using nSDL ? If so, I can provide you a getPixel routine I wrote else, you can find in the file utils.c of the Ndless sample "particles" a getPixel function which deals directly with the screen.

Nope, not at all in fact it has nothing to do with this program. It's something completely different of the tunnel.

@TheNightenedOne yeah it can be helpful I'll first draw a sample for you to see over-looking of it. @tr1p1ea I'll use full pictures for that. @squidgetx yeah I know, but don't worry, I'm only in early testing stage I didn't really care of those details when I made the firsts builds of the engine.

Oh yeah, I didn't think of it that way ...

I created another topic F-Zero : TrackSpire because it's now the subject. So I lock this topic.

THIS POST IS OUTDATED !!! SEE THE LAST PAGE OF THE TOPIC INSTEAD.Hey guys, Since I'm back working on Mode 7, let's make a game out of that For now the Mode7 perspective engine is done, and I wrote a masked sprite routine (for transparency), but that's all for now. I'm actively working on it, so I'll post update regularly Screenshots history (from newest to oldest) : Share comments (if you want to test the program, both files must be in the same directory)

Sprite ! I post with only this small update because it was such a pain to make the texture load relative and the masked sprite routine
