UnitSync :: about function

[danil_kalina]

Where could I find out more information about functions in that library ?

I need a function that returns the state of map's existence.
GetMapArchiveCount ???

We do have a such function for Mods, but for Maps doesn't:
GetPrimaryModIndex(const char* name)

For all downloaded maps "GetMapArchiveCount" returns "2"
For nonexistent maps "GetMapArchiveCount" returns "1"

[koshi]

You're not making much sense to me. I suggest you read the api docs again or maybe have a look at one of the unitsync users like SpringLobby or Tasclient.

[danil_kalina]

SpringLobby loads "MapNameList" and "ModNameList" through iterating all the maps and mods. If we want to find any map we just need to verify it in the list.
I thought of a such way. so no other way exists I think.

I think you can check for existence of a single map like this:

If you get a '0' return value from calling GetMapInfo with the map's name and GetNextError returns a string starting with "Could not find a map" after the call, that means the map doesn't exist.
(See the 'throw' statement in GetMapFile inside unitsync.cpp for the exact wording on error message)

The way the check is implemented internally in ArchiveScanner is by iterating through all maps:

Code: Select all

	for (std::map<std::string, ArchiveInfo>::const_iterator aii = archiveInfo.begin(); aii != archiveInfo.end(); ++aii) {
		if (s == aii->second.archiveData.name) {
			return aii->second.archiveData.mapfile;
		}
	}

So I assume it's not very fast.

GetSides
GetSideName(int side)

How we could retrieve Icon for side(faction) ?
Icon for ARM and CORE

(i know its an old thread, but the question is still unanswerd)

this should help:
http://springrts.com/wiki/Mod_Development:Sidepics



and maybe http://answers.springlobby.info/ is a better place for such questions.

thanks
have to extract the game, then take pictures. not good, but it is ok.

but the icon is in .bmp format and also not fully transparent, WTF ?
why not .png ?

[koshi]

Uhm, are you not aware of spring's vfs? Or is that what you mean?

SpringLobby has been supporting png for a very long time, it's up to the game dev to actually use png.

[PicassoCT]

Yeah, yeah.. its always them gamedevs fault.

[danil_kalina]

Not aware of VFS

[Axiomatic]

Not aware of VFS

Here's a simple example without error checking.

Code: Select all

//load mod
const char *modName = "Balanced Annihilation V7.63";
Init();
GetPrimaryModCount();
int modIndex = GetPrimaryModIndex(modName);
GetPrimaryModArchiveCount(modIndex);
AddAllArchives(GetPrimaryModArchive(modIndex));


const char *sidePath = "SidePics/ARM.png";
int fd = OpenFileVFS(sidePath);
if (!fd) {
	sidePath =  "SidePics/ARM.bmp";
	fd = OpenFileVFS(vfsPath);
}
size_t fileSize = FileSizeVFS(fd);
uint8_t buff[fileSize];
ReadFileVFS(fd, buff, sizeof(buff));
CloseFileVFS(fd);

The sidepic can be BMP or PNG. If its BMP then white is used for transparency.

Thanks a lot. Very nice example
