UE1 - UT Sending information to and from a DLL

[Zur]

Hi,

Is there a tutorial somewhere that explains how to communicate with a dll using unrealscript ? For example, I have a dll that creates a log of some sort and would like the information to be relayed to the uscript part and sent back to the server.

I don't know if there's any tutorials out there about this. Seems do-able using native code. Alternatively, it is also possible to connect using a socket - not sure if there are tutorials for this either but it's not too tough and there used to be some documentation around. I believe that native coding is possible using UT99 but never saw a lot of tuts on the subject.

Since this is about UE1, I think native functions and possibly events are the easiest way to do this. The UnrealWiki should have a tutorial about implementing native functions in UE1.

Here are links to tutorials:

In addition I had a lot of problem with events (UScript functions called by native code) but I've came out with this:

#define NAMES_ONLY
//#define AUTOGENERATE_NAME(name) NEMESISCORE_API FName NEMESISCORE_##name;
#define AUTOGENERATE_NAME(name) extern NEMESISCORE_API FName NEMESISCORE_##name=FName(TEXT(#name),FNAME_Intrinsic); 
#define AUTOGENERATE_FUNCTION(cls,idx,name) IMPLEMENT_FUNCTION(cls,idx,name)
#include "NemesisCoreClasses.h"
#undef AUTOGENERATE_FUNCTION
#undef AUTOGENERATE_NAME
#undef NAMES_ONLY

void RegisterNames()
{
	static INT Registered=0;
	if(!Registered++)
	{
		#define NAMES_ONLY
		#define AUTOGENERATE_NAME(name) extern NEMESISCORE_API FName NEMESISCORE_##name; NEMESISCORE_##name=FName(TEXT(#name),FNAME_Intrinsic);
		//#define AUTOGENERATE_NAME(name) extern NEMESISCORE_API FName NEMESISCORE_##name=FName(TEXT(#name),FNAME_Intrinsic); 
		#define AUTOGENERATE_FUNCTION(cls,idx,name)
		#include "NemesisCoreClasses.h"
		#undef DECLARE_NAME
		#undef NAMES_ONLY
	}
}

Of course NemesisCore stuff should be replaced by you package name. Take a look at SampleNativePackage in public sources or my music player: http://turniej.unreal.pl/files/RMusicPlayer_newbeta.zip, it includes full source code so feel free to use it as a base.

If you'd have any problems just post here, I'll try to help you if I can.

Can't you just call "ucc batchexport <package> class h <dir>" on your UnrealScript package? Or does the DLL have to exist in the first place to compile the script?
