One of my recent interests has been the usage of game controllers on
the computer. A problem with PC gaming vs. console gaming is that
there is a lack of human interaction. In console games, it is
commonplace for games to be designed so that multiple players can sit
next to eachother and play together on the same screen. PC games on
the other hand tend to be much more isolating, with the focus being
more on playing against other people through the internet. I would
like to explore using the PC to make multiplayer games that bring
people together.
The setup that I use is with Playstation controllers attached to the
computer through USB adapters. I don't have any other sort of
controller, so I haven't some games may possibly not work well with
other controllers.
I wrote LineDancerUltra in the summer of 2004 in about 2 weeks. It is
a game with a simple concept and is probably a ripoff of the classic
snake games, but with a twist. The movement of the lines is controlled
by the joystick on a playstation controller. As well, there are menus
for creating player profiles that keep track of win records, player
color, and other statistics. Theoretically, the game can handle as
many players as there are controllers, and I have successfully played
with as many as 3 players at the same time. If anyone manages to play
with more people, I would love to hear about it.
One of the cool effects of the game is the ether that the lines travel
through. If you observe the particles they have a slight jiggling to
them, and the head of the line leaves a wake. As well, there are
powerups that make a splash as they appear. The trails are stored as a
series of line segments that change in resolution according to the
curviness of the trail. I was originally storing one segment per
frame, but every segment has to be drawn and hit checked against per
frame, so it became obvious that some simplification was needed. This
is done by setting a maximum segment length and otherwise, only adding
segments when the direction has changed.
