That's just telling you how to build the Allegro libraries from within Geany. You could also do the same thing from the mingw shell, or just get prebuilt Allegro libraries.

No. You have:
- Two big pictures named planeA and planeB* (and may be window too), usually used to draw background, foreground and/or ground.
- Up to 80 little pictures, named sprites, to draw all other things.

For example, if you character touch a rock on the ground and then it falls, it should be a sprite since his movement is independent from the ground (see sonic 1 and rock-edges falling on level 1).

You can animate titles on a plane (break a window, for example), but they can-t move at its own.

* as they always scrolls, they should be considered infinite pictures.

Chilly!

Hmmmm ... I understand Library is for calls to functions on the Library mkaing a programmer's life easier [Understood]

Chilly, I am wanting to use Geany with allegro like so ....

http://wiki.allegro.cc/index.php?title=Geany

Not for Genesis stuff but Windows game programming.

What do you think of the above link?

Just for information, you can't get 960x224 picture on the SMD if every tile in the picture is unique - it's 3360 tiles total, and you can have ~1900 max at once, in the very best case, and this number is for everything, including sprites. So, you have to plan your backgrounds to be tile-based, with least possible number of different tiles.

Hi,

Thanks ... that helped lift the dark cloud of confusion I had over level building.

I think my approach to level building is flawed.

Sent you a Pm please read it.

I made get_bit routine faster, so it's better to use my unit. Also I add 2 preprocessors definitions. Size of unpacker is 212 bytes (Macros version).

It's old version of get_bit.

Code:

get_bit:
subq.b #1,d5
bne.b still_bits_left
moveq #8,d5
move.b (a0)+,d3
still_bits_left:
add.b d3,d3

Here's new version:

Code:

dbra d5,still_bits_left
moveq #7,d5
move.b (a0)+,d3 | Read next crunched byte
still_bits_left:
add.b d3,d3 | D3.b << 1 (lsl.b #1,d3 o roxl.b #1,d3)

Good optimization!!! But remember, that with the change to dbra, you need to change the initialization of D5 (i saw that you have it in your sources), from:

Code:

moveq #1,d5 ; Initialize bits counter

to:

Code:

moveq #0,d5 ; Initialize bits counter

An in the subject about other crunchers, another interesting it would be exomizer, it compress a few better than aplib and there is two version of the decompressor, a normal and an stream version (a few more slow but ideal for decrunching in background, for example). Of course, it has disadvantages, it needs 156 bytes of ram and there is not an 68000 version, but well somebody can correct the last defect

Each sprite/tile is mapped to one of the 4 palettes, so each tile can have up to 15 colors (or 16 if you care transparent one*), and each sprite up to 15 colors.

*The deeper background can use the background color as own color.

When working with backgrounds the limit are the tiles, so I recommend to start first drawing them (or may be some composition of them), and then compose the background. Or if you like more a very short but intense game, draw all background as a whole, but you have to dinamicaly load it.

You can change the priority of every title to be up or down respect each sprite, so, a background can be a foreground too. A lot of games use this feature to implement one tile map only and save memory.

Each moveable independent 'thing' should be a sprite since planes are a whole thing. So all dependent drawings go to a plane.

You are very limited (MD has more than 20 years), so it is pretty clear that you can not do; but at first stages use only your imagination, do not think about limits.

Well, of course I know that there are NO THE BEST compressors. Sometimes one is better, sometimes another. But one can be better more frequently. That's why we need complex criteria and take into account speed / size / RAM, etc.

preview.bmp is not that case of data which you expect to decompress in MD games. Real MD graphics consist of additional tilemap and usually are more complex.

Anyhow, aplib overtook RNC.

Hrust and Bitbuster are weaker

Get SixPack, and try to pack /demo/smd/preview.bmp. You'll see the case when BitBuster is more effective than Aplib.

By the way, I've just found version of the BitBuster for MSX which depacks data directly to VRAM, and it was based on .. Aplib ported to Z80, for Sega 8-bit consoles, which also has version to depack directly in VRAM.
