Texture recognition tool for Starcraft II Maps

Made to be used in Ice Escape like maps for StarCraft II.

Native API function string TerrainTexture (point pos); has its precision limited to one square (max size of a map is 256x256 squares). Thus it's unusable in cases where precise results are required. Because the square in reality is built with 8x8 pixels.

This tool parses t3TextureMasks binary file that stores complete data about terrain pixels and their blending value. This is then translated into TextureMap.galaxy script file which maps the data into string array upon initialization. Size of array is 8 per square Y (can go up to 2048). Length of each string follows same convention.

Generated file example

// snow_index=3
// snow_value=13
string[2048] tm;
void initTextureMap() {
tm[0]="1234567812345678";
...
}

Example implementation

const int SURFACE_SNOW = 1;
const int SURFACE_LAND = 2;
const int SURFACE_NORMAL_ICE = 3;
const int SURFACE_REVERSE_ICE = 4;
const int SURFACE_STRAIGHT_ICE = 5;
const int SURFACE_FAST_ICE = 6;
const int SURFACE_REVERSE_FAST_ICE = 7;

static int sd_mapTextXY(int x, int y)
{
    return StringToInt(StringSub(tm[y], x + 1, x + 1));
}

int sd_getSurfaceAt(point pt) {
    int i;
    int x;
    int y;
    int intX;
    int intY;
    fixed pointX;
    fixed pointY;
    int surface;

    pointX = PointGetX(pt) * 8.0;
    pointY = PointGetY(pt) * 8.0;
    intX = RoundI(pointX);
    intY = RoundI(pointY);
    surface = sd_mapTextXY(intX, intY);

    if (surface != SURFACE_SNOW) {
        return surface;
    }

    // this part is to introduce extended margin tolerance
    if (surface == SURFACE_SNOW) {
        for (y = -1; y <= 1; y += 1) {
            for (x = -1; x <= 1; x += 1) {
                surface = sd_mapTextXY(
                    RoundI( pointX + (IntToFixed(x) * 0.2) ),
                    RoundI( pointY + (IntToFixed(y) * 0.2) )
                );
                if (surface != SURFACE_SNOW) {
                    return surface;
                }
            }
        }
    }

    return surface;
}

Returned texture ID corresponds to mappings inside t3Terrain.xml:
