Hi,
Ive been looking for an engine thats 3d, but not with polygon based maps. In the old sega game Sonic and Knuckles (or Sonic 2), there are parts where you are in a third person view (the player is viewed as a sprite) and you are on a revolving globe. You move around the globe and objects get closer or farther away from you. I would like to know if there are any engines similar to this, with sprite objects that get closer to you as you move forward, but just with a flat ground. I would imagine that the only polygon that would be on the map would be the ground. Every other object would consist of sprite images that merely grow bigger as you move closer to them. Might anyone be able to refer me to an engine like this? If it's a bit different than what I described, I'm open to ideas. I'd hope something like this isnt too complicated or hard to work with. Well, please let me know. Thanks!

hmm, I wasn't aware of 'Modes' Keep in mind that I'm using the demo version. Are these modes you speak of in the Pro version only?

There aren't multiple "modes", "Mode7" is an extension that horribly emulates 3D much like in Sonic. There is a good chance that game used Mode7 techniques.

 
thinking is like pong, it's easy, but you miss sometimes.

Oh I see. Well would you mind explaining to me, step by step, how to 'get into' mode 7?

The 3d effect in sonic and knuckles' special stage is done by pallete swapping colours, but is very complicated to recreate, and i'm not aware of an extention that can do that in MMF. This is the same method 2d games used for racing games (super hang on and such)
sonic 2's special stage was simply an animation.

mode7 is the common name for an effect which creates a flat plane which can be texture mapped like what is used in mario kart games. Mode7 was actually the graphics mode on the super nintendo that uses this effect, but because it was most publicised as 'mode7' thats what everyone calls it, I can't remember the real term for it.

If you download the mode7 object for MMF you should get examples that will help you use it, but it wont get you what you want.

Now i think about it, Sonic cd does use this effect for it's special stages, but it was never possible on a standard Megadrive/Genesis.

Thanks again for your replies. I downloaded that extension and was very impressed. But it just seems like a whole new language to me now. I suppose the Sonic example I brought up wasnt the best one, just what came to mind. I am in fact looking more for a mariokart example. But I think I'll stick with my isometric game now, seeing how this engine looks. I've tried several examples and cant seem to work with them very well. Plus it seems very hard to get a big map and have it look semi detailed when the player is walking on it. Well, thanks for the help anyway!

check my downloads if you're doing a top down game for a 3d like effect.

Thanks. Actually I was planning on doing a mariokart like effect, where sprite objects get bigger as you approach them.
