yeah, I would do marble madness, but first I would convert this to an axiom and make it faster before I made a product with it.

An axiom would actually be cool, if we can customize it and stuff. It would allow for more projects :D

Axiom Isometry Games would be interesting. However, I can't really see what kind of games could be made with this engine :S I can only come up with Habbo :P

I think this engine, while still long ways away from being immaculate in speed, size, and graphics, can still be used for some really cool projects; I can think of at least 50 different ways to use it, like a 3D pinball or rollercoaster creator

How about a rollercoaster game with a pinball machine attached to the coaster seats ;D

Is there a pinball already?

Well, I prefer 2D Pinball, but that would be interesting to code :)

no pinball in quasi-3D yet, but there was a most excellent one on ticalc that had a really long and weird name that started with an 'A' that was awesome.

I don't think that's likely to happen.  Nobody is going to want to be limited to the built-in sprites, and I really don't think that axioms are that customizable, but I wasn't around when they were an option, so idk.  The most I could give is something that calculates X and Y from X, Y, and Z, a 16x16 Pt-Mask(), and a couple rect()'s.  That comes out to (in unoptimized axe, ASM would be soo much easier):
Spoiler For big code block:
Code: [Select]
:Pt-16-Iso(X,Y,Z,Pic_16_With_Mask)

:[00000000]->Str1  .temporary memory space, so we don't have to use named variables (won't work with apps)
:r1-r2*8->{Str1}                   .X on screen
:r1+r2-r3*4->{Str1+1}           .Y

:.Draw the two bottom lines any which way, I used masked sprites :P

:.Just in case Y is off the top of the screen (can be ignored if that limitation is removed)
:If {Str1+1}+16<<0
:0->{Str1+2}
:r3*4+{Str1+1}+16->{Str1+3}
:Else
:{Str1+1}+16->{Str1+2}
:r3*4->{Str1+3}
:End

:.Connector lines
:Rect({Str1},{Str1+2},8,{Str1+3})
:Rect({Str1}+8,{Str1+2},8,{Str1+3})  .Because if X is off the left side...
:RectI({Str1}+1,{Str1+2},6,{Str1+3})
:RectI({Str1}+9,{Str1+2},6,{Str1+3}) .same

:Pt-Mask_16({Str1},{Str1+1},r4)

Main problem with my current setup is that I have to draw so many rectangles and do so many calculations.  The task is trivial in ASM, as, for the connector lines, all you have to do is load $8181 to a column...

On second thought, an axiom would be so useful.  However, a X/Y offset argument would be useful, especially for smoother scrolling (just add or subtract from the initial X/Y calculations).

I'm having trouble with compression in my program, tho.  It works perfectly fine with uncompressed data, but when I try to compress something, it messes everything up. :(

The compression should work like:
Spoiler For compression example:
Code: [Select]
Uncompressed data:  (format: [TTXXYYZZ], TT=tile type)
[00010101]
[00020101]
[00030101]
[00040102]
[00050003]
[00050102]
[00060102]
[00070102]

Compressed Data:
[F00007]  //make T=00 for 7 blocks, not including exceptions... lol oxymoron
[F1010107]  //auto-increment X, and keep Y=01 for 7
[F30103]  //make Z=1 for 3 blocks
[FF] //ignore me and loop, stupid program
[FE00050003] //EXCEPTION! ignore everything else and interpret this as uncompressed
[F30204]  //make Z=2 for the last four blocks
[FF] //:P
That compresses 32 bytes to 20 bytes!!! (most maps would get a much better ratio)

PS: the compression codes were specifically chosen to represent the task they perform, for example, F1 replaces bytes starting at 1, FE is an exception...

I would do a Java map editor. I know a lot of Java.

I think maybe an Axiom that does the tilemapping based on window settings and tilemap width would be actually pretty neat!  You could have a setup function where you could give it the Matrix address, the sprite address, and the mask address, the map width and height, and the window size and it would be all set up.  After that, just a simple Draw(X,Y) would render the screen at that point! With maybe a couple more commands for drawing isometric sprites.
