Anyone managed to get irrlicht/ogre/glscene/etc going in blitzmax yet?


JaviCervera(Posted 2004) [#2]
No, mainly due to the poor support for dll's. Ok, BMX allows you to code modules in C directly, but what happens if you don't have the source of these libraries and only a .dll? AFAIK the only way to call dll functions right now is by using the WinAPI. That completely sucks for a multiplatform programming language.

There should be a way to define functions which are in external dlls inside .bmx, so you can create modules that can call functions from these dlls.

You need to write wrapper functions in C and use the Extern/End Extern construct in BMX to import your wrapper functions. If you review brl.freeaudioaudio and pub.freeaudio you'll see how BRL does this with FreeAudio.

No, it isn't pretty and certainly not as simple as what Mark had come up with for Blitz3D/Plus. I'd make a guess this approach was adopted due to the cross platform nature of BMX.

Uhh, you realise of course that .dll's are a Windows only thing anyway, right? ;]

Some people only want their project to be run on winders... some may only want their project to run on macs... Having some platform dependence shouldn't stop someone from doing something.

Hm, bit of a pain then.

True, but read Jedives post again.

Well yes, using something that's exclusive to Windows is going to 'suck' if you wanted to do a multiplatform version.

I was under the impression that Ogre3D was OpenSource?

Yup. Irrlicht and GLScene are too. All Irlicht SDK downloads seem to include full engine source.

No, but in the same line he went on to say

Which threw me a bit =]
