I just had an awesome dream a few minutes ago, and I cannot sleep anymore, so I'm posting this topic about it. I dreamed I was playing as Tiny Kong in a 3D level. There was music I never heard before, with recognizable sound effects from various games. The point of this was a demo "mini"-level (though quite large anyway) and you had to collect a whole bunch of stuff. Losing too many lives resulted in loss of all the "star" items (think DKC3 bonus level kind of star but with a red outline on them, in front-facing 2D mode). There were also, among other things, a Triforce to be found in this level, Bear Coins, Golden Bear Coins, and bananas of course (there may have been other items, who knows).
This gave me a radical idea: What if, at some point, I were to apply 3D to the DELTA game physics rules and create an extension called "3D Level Mode" that could be called up instead of the usual 2D engine mode? I've had this idea beforehand, and its codename was previously known to me only as as "SIGMA", still being an idea for an entirely separate future engine experiment. But I just realized - what if I were to take this idea and make it part of the Delta Project?
Although; some preliminary thought suggests that this would be more complicated than it sounds - about 10 times more complex, at the very least. A few big hurdles such as how to integrate this into the already existing engine, how to edit levels easily, and how to prevent objects from going into walls in the physics, are a few of the worst issues with this idea. The same rules that are in DELTA's 2D physics can be applied to any arbitrary plane in a 3D space, but it would only consider point-line collisions, not the actual 3-dimensional hitbox (hit-spheres, collision-mesh, or other such things).
So, what do you guys think? *votes under the Maybe category*
