i just finished a beta version of my engine and sent it to a friend to check it out. He says everything works dandy but the mouse motion is inverted. he moves the mouse up, the view rotates down. he moves the mouse left, the view rotates right. Everything works right on my computer. any ideas??? THE swoish

Maybe he uses one of those USB remote mouses or something like that

Tell him to turn his monitor over.

snisarenko, what problem does a USB optical mouse have? Is there any kind of flaw in their drivers or what? I just need some kind of lead to follow.

Why don''t you just reverse the mouse input?

I would try it on his computer to make sure its going backwards.

Yeah, that''s really a relative description. It''s why games like Halo (and just about every other shooter (except sometimes those with completely configurable key maps)) have an Invert Mouse/Joystick/Whate''er option. Having been used to PCs, I was really disoriented with the standard Halo settings, but I can do fine with the vertical motion inverted.

It all boils down to whether you think of the controls being tethered to the viewpoint more like a handheld video camera or an airplane yoke.
