Re: I can\'t extract the sprites from the .exe
 

Indeed! The great majority of my modding time is currently spent on extracting exact sprites - and I've only completed a handful.

I can\'t extract the sprites from the .exe
 

Maybe I'm just being dense, but I'm posting this so that no-one else has to duplicate my wasted effort http://forum.shrapnelgames.com/images/smilies/happy.gif. The long story short - the dom3 executable is only 5 MB, so they obviously aren't using .tga or .rgb to store O(2000) sprites.

Has anyone else had any success *finding* all the unit sprites buried in the executable itself?

I started on the assumption that all the unit sprites would have little .rgb or .tga headers.

So, I find specifications, here they are:
http://www.fileformat.info/format/sgiimage/
http://www.fileformat.info/format/tga/egff.htm

rgb file headers are supposed to start with the "magic number", 474. That'd be 0x01DA - and yes, the .rgb map files generated by the random map generator start with 01DA. Unfortunately 01DA only appears twice in the executable.

So, either the internal sprites aren't in rgb format, or they are, but part of the header is stripped off. Don't these guys know that programmer time is far more valuable than incremental performance improvements!?!?

TGA file headers don't have any magic numbers in them - so I'll try to find some headers in some custom sprites that Frank drew, and hope they're the same.

The header of a .tga file is 18 bytes long. I figure if any of this header info is retained, it'll be the size of the sprite, which is bytes 13-16 of the header.

This is 0x00800018 from Frank's .tga sprites.

Unfortunately, 00800018 doesn't appear at all in the executable http://forum.shrapnelgames.com/images/smilies/frown.gif.

The actual begining of Frank's .tga sprites is:
00 00 02 00

So, I counted those occurences - 1,478. That sounds (about) right, there are O(1000) units, 2 sprites each but many of them share sprites, so I tried splitting on 00 00 02 00.

I get 1,478 "tga" files but I can't actually open any of them. On examination I notice they're much too small.

This is when I did the math - Frank's .tga sprites are 50K each. 1000 such sprites would be 50MB. The dom3 executable is 5MB. Boy do I feel stupid.

trees.r3f is about the right size, though.

It has only 523 "00 00 02 00" in it (and no 01 DA) and I'm pretty sure this file is full of background wireframes for the tactical maps.

Ah well.

Re: I can\'t extract the sprites from the .exe
 

if the sprites are being stored in the exe, they probably know exactly where the are and what format they are in so they would have no need for headers, just the raw data and the dimensions

Re: I can\'t extract the sprites from the .exe
 

They arent in the exe.
Mostly its the files that start with 'army' which if you are lucky might be the same format

Re: I can\'t extract the sprites from the .exe
 

They are army.trs etc. It is no conventional format and is only used in JK's own program spooky sprites. I don't know anything about formats, but I suspect it might be difficult to extract them. It is possible to make tga's from the sprites in spooky, but I'm not sure if you can extract a whole bunch at a time. If so I could probably make a library of tga's for modders.

If you would do so you will be worshipped as a god even more than you were before http://forum.shrapnelgames.com/images/smilies/happy.gif

I second in saying that this would be the coolest thing ever.

Whoah, an Atari Falcon. That takes me back. My parents wouldn't buy me one, but a couple of my friends had those.

If I can find an Atari Falcon emulator (check) and one that supports scripted input (not bloody likely) and then get a copy of JK's old freeware version of Spooky Sprites then, assuming the binary format he uses is the same, and assuming the old version supports extracting files into any sort of bitmap.... hmm....

It's a holy relic from a bygone age! :O

Indeed! Praetarius, that was a great find!

Re: I can\'t extract the sprites from the .exe
 

Some time ago I created a gimp perl plugging to extract the dominions:PPP images from the files.
I was able to get the item files almost pefectly, they just were stored with no compression, 1 byte per pixel using 2-3bits per colour channel (or just got lucky with the colours).
IIRC the unit files had some sort of pallette and a kind simple of RLE. I got the centurion (was the 1st one) mostly ok from the 1st army.trs file, the other files used another set of colours.
The script got lost in a format&write-wrong-partiton accident so was never posted anywhere...
So start your hex editors to check the files and show your ninja coding skills.

Re: I can\'t extract the sprites from the .exe
 

If it's possible to create a single image containing all the sprites, that could be a quick and simple way of providing all the sprites for modders and would be entirely sufficient (especially if lateral offsets in each sprite are preserved or somehow inferrable) in my opinion - modders can crop out individual sprites as needed.

Anyone knnow anything about Atari? This is your chance to prove its power! http://forum.shrapnelgames.com/images/smilies/wink.gif

Re: I can\'t extract the sprites from the .exe
 

The download URL seems broken. Does anyone have the file?

Re: I can\'t extract the sprites from the .exe
 

Has anyone explored this further? This approach would be MUCH better then my planned automated screen shot capture method.

I guess everyone is hoping KO will come through and save us all the trouble http://forum.shrapnelgames.com/images/smilies/happy.gif

Re: I can\'t extract the sprites from the .exe
 

spooky4.lzh extracted and re-packed into spooky4.zip.

Anyone up to launching this old, old version of Spooky Sprites and seeing what happens?

Re: I can\'t extract the sprites from the .exe
 

If someone is able to get this software working well enough to extract 1 sprite I can probably build a macro that can automate mouse movement, clicks and sending keys to the program.

So assuming you have to manually extract each sprite (vs having some kind of batch command) I could likely setup something to "batch" it.
