Hi,

In fact, just as I said before, all data structures of this engine are based on python basic type data structures. 2d vector type is just same as complex type in concept and C implementation, so I just use Python complex type and add some functions for advanced vector usages. I think maybe it's not a bad idea to treat physics 2d vector space as complex number space. But I also separate the main code from vector code, replacing it with a distinct vector type will be easy, maybe it will support it after the first stable release.

Best Wishes

Zhang Fan

Hi,

I had a quick look at the vector code in SVN. I see that the glVector2d
is just a Python complex type. Is this simply for prototyping? Will the
finished module support a distinct vector type?
