The two programs I have separate are 753 and >500, but they share a lot of the same code, so if I combine them, it will be much smaller (and the actual engine part will probably be >700 bytes in all ._.)  Yours looks quite wonderful, Matrefeytontias o.o Can the tiles work with a different number of frames, or all they all the same number of frames?

I use 3 tiles, each with a different number of frames : the first one has 4, the second one 3 and the third 1. The number of frame for the Nth tile is defined by {N+1+GDB1OFST} - {N+GDB1OFST}.

Oh, I see it now :D I didn't see the 4-cycle tiles. Nice! :D

Okay, my program is getting on the large side, now :/ I have the following done, though:

-Smooth scrolling 1 pixel at a time through 8-pixel steps
-Boundary detection (so that garbage isn't shown if you scroll off the map)
-Animated tiles
-60FPS (It is actually a few FPS faster than before when there wasn't animation o_O)
-Arbitrary map sizes (they can be any width/height from 1 to 65535)

The downside is that minus all the data and stuff, the map engine itself is 1192 bytes (at least I'm pretty sure I removed all the extra stuff .__.)

Still looks cool :0 hmmm if it's only movement, i think we'll defenetly need an app xD (or aren't you tht good at axe? Cause i most of the time have: i use +- good routines but much things that could be optimised, like using r r1-6,...

Well, I'm not too good with Axe and there are ways to optimise this more for size (I was optimising for speed, mostly). I also use about a hundred bytes of optimised assembly, directly XD I think that if I put this all in assembly code in an app, I could make it a little more optimised and maybe even faster (depending on how Axe handles drawing sprites).

Looks great Xeda! Why does the animation speed slow down in the second part of the screen shot though? ???

Size isn't that much of a problem since if we use my PageSwap axiom, we'll have 40k of executable code with only one app and Crabcake/fullrene.

Initially, I use a delay of 8192 (2^13) for the animation speed. Every time the screen is moved, I add 1024 to the delay counter (because that is about how long it takes to shift the screen). In the later part of the screenshot, when I shorten the delay to 1024, this means that every time the map is scrolled, it gets updated and the timing is slightly off.

I modified the code I have to use potential sprites (instead of the simple circles). Unfortunately, I messed up on a few frames, so it doesn't look too nice for the tall grass, but I'll leave the spriting to others XD Remember, this will work on the TI-83+ since it is still 6MHz :)

I also was too lazy to finish the map, so I filled it with 0s >.> I should really make use of TileCat or something (I'll probably have to make an on-calc map editor again). Also, as you can see, it uses 8x8 tiles, though a bunch of the tiles are part of a complete 16x16 tile. I have made plans for a tilemap routine that could handle variable size tiles (so you could have 5x5, 11x11, 8x8 , 16x7 tiles all in the same map, for example), but scrolling was too complicated for me to add that in XD It also requires a decent amount of extra RAM :/ (about 200 bytes).

Looking good! I dont think arbitrary tile sizes are necessary, especially when this is specifically made with a project in mind.

I agree. It really just need to support whatever size we decide that we are going to use. :)

Thanks! I will say that it will be slightly more of a pain to use 16x16 tiles, but I think we can use 8x8 tiles to look like 16x16. I wish I was better at spriting and finding good timing for animation XD

Posted from cell earlier. I can actually see the screen shot now. Looks nice. :) Why do you think 16x16 would be more difficult?
*Edit* oh, and i wouldn't worry too much about timing. It can fine tuned later. :)

Oh, actually coding it to read the data from 16x16 sprites will be a pain for scrolling. I'll probably eventually do it, but it will require a decent amount of motivation for me XD I also have that issue where I like to make sure the program is efficient, so I will need to set aside several days where I can focus on perfecting it XD I'd probably also prefer to do that in actual assembly code.
