Roadblox.dat file stores information about creation of police roadblocks on the map in GTA San Andreas.
Format
The file begins with the parameter - count of used roadblocks. It is followed with information about these roadblocks. Details of one such roadblock includes path area id, and path id in this area.
typedef struct NodeInfo
{
int16_t areaId;
uint16_t nodeId;
} NodeInfo;typedef struct RoadBloxFile
{
int32_t count;
NodeInfo places[325];
} RoadBloxFile;Editing
The file can be edited, but its size should not be smaller than the original. Parameter "count" can be set to "-1" (in this case, information on the roadblocks will be ignored).
Example of file reading
int main()
{
NodeInfo info;
int32_t count;
FILE * dat = fopen("data/paths/roadblox.dat", "rb");
FILE * txt = fopen("data/paths/roadblox.txt", "wt");
fread(&count, 4, 1, dat);
fprintf(txt, "count: %d\n", count);
for(int i = 0; i < count; i++)
{
fread(&info, sizeof(info), 1, dat);
fprintf(txt, " %3d area: %2d node: %3u\n", i+1, info.areaId, info.nodeId);
}
fclose(txt);
fclose(dat);
return 0;
}
