Actually, I'm currently looking at the plugin SDK, I don't have purebasic, so I'm making an attempt (vain though it may be) at converting it to Delphi.
Since I don't have purebasic, I know little to nothing about its' syntax.
I am having trouble with Gile[s]-structures.pb, the mesh structure contains what appears to be a pointer to a polybank structure, but I can find no declaration of this structure in the supplied files, is this a standard pb structure?

*EDIT*
I may have just made a simple error (yet again), it looks like it's a pointer called polybank.
*duh*
