Then you have all the tools.h file to handle manually decompression but if you use advanced method as VDP_drawImage(..) or VDP_drawImageEx(..) SGDK will handle it by itself (same for the new TileCache feature).

How use this function: Image *allocateImage(const Image *image); ?

/**

* Allocate Image structure which can receive unpacked image data of the specified Image.
* If source is not packed the function only allocate space for simple shallow copy of the source.
*
* \param image
* Source Image we want to allocate the unpacked Image object.
* \return
* The new allocated Image object which can receive the unpacked Image, note that returned image
* is allocated in a single bloc and can be released with Mem_Free(image).<br/>
* <i>NULL</i> is returned if there is not enough memory to store the unpacked image.
*/
Image *allocateImage(const Image *image);

And the Image structure is build from your IMAGE resources (see the rescomp.txt file for more details).

Oh really ? I do not use any win api stuff so win XP, win 2000 or whatever should not be a problem. I tried to make it cross platform... You have the sources in the tools directory if you want to give a try

But in the meantime, can your report me the error you got on win XP ?

sample/sound

sample/sprite

Oh, i think it's just a problem from the '/' character used to separate folder... this indeed may not work on win xp (but does on win vista and after). I need to fix that !

Hi again Stef!

How to I generate the *.h file from a res/*.vgm now?

In SGDK 0.94 I only put the vgm into the res folder and I included the *.h in my code

Another question, Is Html sgdk Documentation outdated? I don't find the new functions

hi nolddor,

You have to use .res file to declare your resources (as the VGM file).
you can look in the provided "sound" sample to have an example

I know it looks less user friendly to do this way but it is far more powerful as you can handle many more different type of resources ans set extra parameters !

Should be fixed !
You can redownload the whole SGDK archive or just take the last rescomp.exe from here:
http://sgdk.googlecode.com/svn/trunk/bin/rescomp.exe

Hi

What's the problem with VDP_setTileMap()?

After installing SGDK 0.95, I have this message while compiling: (without any changes in my code)

Code: Select all

gestion_map.c|49|error: too many arguments to function `VDP_setTileMap'|

My command is :

Code: Select all

VDP_setTileMap(BPLAN, TILE_ATTR(0,0,0,0)+(z), k, l);

(Same error without "+(z)"...)

EDIT : Ok, I have to use VDP_setTileMapXY(); instead...

Seems to be a wrong deprecation... Sorry for the problem !

Hello Stef

I get to compile on eclipse my main.c

But i would like to learn to compile in dos only.

In my project i copy all

src , res, inc in my drirectory project.

and i start %GDK_WIN%\bin\make -f %GDK_WIN%\makefile.gen

I don't get in my out directory , the bin file.

Do you know why ?

thanks

Edit : i find, sorry, we must to start cmd dos in admin user.

Hi pckid,

Sorry i didn't see the message sooner but the bug you got is actually a bug from GCC which happen randomly (sometime it crashs without any reason). You just have to restart it and it will pass

pckid · Post by **pckid** » Thu Mar 06, 2014 10:33 am

Thanks Stef,
i send so on the Gamopat Forum, cause we speak together with touko there.

But, if i start my cmd dos in admin user (right click), the compile work fine !

I saw the code to move sonic, it's you which write this ? great code

Stef · Post by **Stef** » Thu Mar 06, 2014 11:48 am

Weird that admin rights fix that issue but if it does

Yeah it's me which wrote the sonic sprite example, thanks for the comment

It could be improved in many ways but it was to show quickly how use the SGDK sprite features
