Load .sbx map to Blitzmax?


Recommended Posts

You can run the Leadwerks engine using BlitzMax to load and render the sbx files, is that what you are meaning? You can't render the levels from an sbx file using just BlitzMax, at least not without writing a parser and handling all of the loading and rendering work yourself.

You should do something like this to load everything.

yup... of you expose the framework to lua (see pass to lua the state section in Joh's code above) then lua will take care of all the parsing of the sbx file, and should load the scene as it appears in the editor...

how to do this in C#?
