Any program that can create .sp2 files?

[decino]

It should be possible, WODX and Gloom use custom .sp2 files (animated sprites), but I can't find anything on Google or w/e.
I know a .sp2 contains x sprite.pcx files located in the sprites folder, just don't know how to merge them into a .sp2.

Anyone knows a program?

Wasn't it the same tool that makes .cin files?

qtool?

Paril knows all this. He even started a new sp2 editor once. Don't think he finished that program.

Last pak I made, I edited the BFG blast sprite to make it red. Basically I used GIMP and the colorize function to change the color to red. It took a bit of work to hand edit the pcx files to where I could make the alpha color stay the same. Saved all the new ones to PCX. Then converted the PCX ones to PNG and made the pinkish alpha color transparent since I use R1Q2 that can handle PNG images.

I'm not exactly sure what all an SP2 file would contain. Is that basically the open_gl rather than software version of the graphics? Would such a file also contain data for a BFG blast like the green laser beams and little green particles that come from the BFG ball? Reason why I ask... I'd like to be able to change whatever I need to change in order to make those red as well.

The SP2 editor, is a easy to use PCX (to) SP2 maker..

An sp2 file just references the .pcx files that define the sprite over time. It's kind of an index into the sprite files the engine needs to animate them. Create your sprite .pcx files and then use the tool pointed to by Ruiner and X7 to create the .SP2 file. Note you will have to place the .sp2 and the .pcx files into the appropriate sprites folder or install them together into a .pak

Heheheh. I had looked all over the net for a .sp2 editor but couldn't find one, so eventually I programmed my own. The file structure is really very simple, like this:

/*
 * The file header for the .SP2 file.
 */
typedef struct
{
char * type;   /* magic string, must be "IDS2" */
unsigned long fver;   /* file version, must be 2 */
unsigned long frnum;   /* number of frames in the sprite */
frame_t frames[];   /* the frames of the sprite (stack declaration because not normally very big) */
} sp2hdr_t;

/*
 * Each frame of the .SP2 file (80 bytes)
 */
typedef struct
{
signed long width;   /* width of the part of the image you want to use */
signed long height;   /* height of the part of the image you want to use */
signed long xorig;   /* x-position of where the upper-left corner of the image is */
signed long yorig;   /* y-position of where the upper-left corner of the image is */
char * q2path;   /* string telling where the .pcx file is (must be 64 bytes long, 0x00 terminated)
                               for example : "sprites/blorb/borb_1.pcx" */
} frame_t;


This is also in the order in which the data gets written out/read in.
Also, it is little-endian on Windows machines; unsure about others.

The struct is found in qfiles.h in the original quake2 v3.21 source release.

/*
========================================================================

.SP2 sprite file format

========================================================================
*/

#define IDSPRITEHEADER   (('2'<< 24 )+('S'<< 16 )+('D'<< 8 )+'I')
      // little-endian "IDS2"
#define SPRITE_VERSION   2

typedef struct
{
   int      width, height;
   int      origin_x, origin_y;      // raster coordinates inside pic
   char   name[MAX_SKINNAME];      // name of pcx file
} dsprframe_t;

typedef struct {
   int         ident;
   int         version;
   int         numframes;
   dsprframe_t   frames[1];         // variable sized
} dsprite_t;


MAX_SKINNAME is 64.

Thanks all, I figured it out a week ago.
I still think hex editing is the most easy way to 'create' sp2 files.
