A new video tutorial has just been uploaded showing how in the Blender game engine you can load a next level stored in a different file.
The tutorial also shows how information can be passed to the new level (in the tutorial a score). To do this the ‘global dictionary’ object is used (in Python bge.logic.globalDict), which is a relatively easy way to pass information between objects (and files) without having to send messages.
The original ideas (and files) were taken from the Blender book ‘the Blender Gamekit 2nd Edition’ which was written for version 2.49 of Blender. The files are adapted to work with 2.5x and are demonstrated in the tutorial, then a simpler version is worked through.
