[TuxKart-devel] Split-screen mode.

[Steve B. <sjb...@ai...>]

(CVS commit emails don't seem to be working...Doh!)

I've just committed a bunch of changes to make TuxKart able to
render 1, 2 or 4 views of the track at once. (Use the num-players
GUI widget to select how many).

It's nowhere near finished yet - but I've had enough for tonight
and it's still playable - so I committed it anyway.

Known issues for me to fix tomorrow night:

1) It needs some kind of a line between the windows to break up
    the graphics somewhat.

2) The status displays are not changed yet - so you can only see
    player zero's bonuses - and things like the map have to be
    moved and/or shrunk.

3) You can still only control one kart right now.

I played a bit with the fields of view to try to keep things
reasonably large on the screen in the more split up modes.  It's
always a compromise between field of view and size of objects,
so in the 4-way split, your field of view is a little smaller
than usual but your cart isn't a fly-speck on the screen.  In the
2-way split, your horizontal field of view is wider than usual
but the vertical field of view is cut down a bit.

There are serious problems with three or four people sharing
a keyboard(!) - not just a matter of how many people you can
sit in front of one keyboard - it's also a matter of this
problem:

...which is **nasty**.

We could make it work with four joysticks (but who owns four
joysticks?)...or two people using the keyboard, one the mouse
and another the joystick.

Dunno - maybe four player is pointless - but it's easy to do
and handy for debugging AI characters.
