Hello,

a friend of mine is working on a game using Delphi. He has got a problem with saving the map-files and I wanted to help him with coding, but, to be honest, I never used Delphi before. Now I thought about creating a DLL and was wondering, if my friend could use the (D-)classes as I placed them in the DLL? Maybe anybody has some expieriences with DLLs and other languages (especially Delphi ;) ).

Regards,
Alex

D can't export classes. You have to export functions (with C or Windows linkage) and call them from Delphi.

When you export D functions in a DLL, can it still uses garbage collection and classes internally?

Could you create "global" classes and wrap their member methods using C stdcall functions exposed in the .dll?

I also use Delphi (its GUI designer is excellent), but it would be awesome if you could program the logic in D and the GUI in Delphi.

I don't think there'd be any problems.
