Frequently Asked Questions on SM3

What is DevIL

DevIL is the Image Loading library that spring uses. http://openil.sf.net/

DevIL supports loading of bmp, dds, gif, jpg, png, pcx, psd, psp, tga, raw, pal, tif, pal, sgi, hdr among others.

"Map Size (x) should be equal to GameAreaW and GameAreaH"?

For the map to load you need to add these two variables to your .sm3:
GameAreaW=xxx;
GameAreaH=xxx;
The map size(note, not the heightmap size which is map 1 pixel) width/height goes here.

How do I use external textures?

Create a modinfo.tdf textfile in your mapname.sdd. It should contain:

[MOD]
{
Name=mapname;
Description=your description here;
ModType=0;

NumDependencies=1;
Depend0=texturefilename.sd7;
}

This will tell Spring to look in the directory where your map is located(eg. \maps\) for the textures you have specified in the SM3. Example:

[Rock]
{
TileSize=60;
File=textures/rock/rock.jpg;
Bumpmap=textures/rock/rock_normal.jpg;
}

Which would tell Spring that your texture is at texturefilename.sd7/textures/rock/rock.jpg.
