Rotation of the 3D view window affects direction of gravity?

I’ve been working through a game tutorial (Chapters 9-10 from Tony Mullen’s Mastering Blender, for those familiar with the book), and I ran into an interesting problem when I imported the character to the scene.

When I’m in the front view in the 3D window (numpad 1), and press play, the character falls down in the -Z direction, as it should. But when I rotate the view to any other angle – side view, top view, or anything between the three main views – the character “falls” in the +Y direction when I press play.

When I put the window in front view, then placed a camera looking in the angle I’d like to use to view the scene, then switched to camera view and pressed play, the character fell in the +Y direction again.

Obviously I want my character to fall in the -Z direction, but I need to be able to view the scene from another perspective in order to play it. How can I fix this problem?

(BTW I’m using Blender 2.49)

I really have no idea. This ssounds strange.

This does indeed sound strange - there must be some sort of error with that particular build of Blender. I would recommend using a later build of 2.5, or perhaps get a 2.49 build from Graphicall, if they’re still there.
