3dpong - three dimensional Pong clone
3dpong display1 [display2|--computer] [--gravity g] [--net n] [--sound]
3D Pong is a three-dimensional clone of the ancient computer game Pong
for the X11 window system.
There are three modes of play
One player mode agains the computer
Two human players, each with their own view at the game
One human player against gravity. This is like throwing a ball
at a wall
The player(s) is presented a three dimensional view at the arena.
There is a white divider in the middle, or possibly the net. The
player one's paddle is a red square, the player two has a blue paddle.
The current score is displayed in the upper left corner. The ball is a
green diamond, and dark green markers follow the ball on the walls to
display it's position in relation to them.
The player(s) controls a paddle at one end of the arena with mouse
movement. To serve, the player presses the mouse button three. The
key c toggles whether the player needs to keep the mouse button one
pressed while dragging the mouse. See also the --noclickn switches
Six views exist, switched amongst with the key v
normal 1st person perspective from behind the paddle
Side view, with the paddle on the left
above From above, paddle on the top
Any angle the user selects, by pressing mouse button two and
dragging the mouse
follow the ball
The view follows the ball
follow the paddle
The view follows the paddle
Key 3 toggles red/blue mode to be used with appropriate 3D glasses,
with red for the left eye.
The game quits if the q key is pressed.
The game goes on until quitted. In the one or two player games the
ball gets faster and faster until someone scores. Players score by
getting the ball behind the opponents paddle. In the handball mode the
player scores every time the ball bounces off the paddle, and does not
go to the goal. The high score will kept for the session.
The switches display1 and display2 specify the X11 displays for the
game. The first is mandatory, and ``$DISPLAY'' is often a good value
for it. The special value ``computer'' means that only one human
player is to play, the other will be a computer player. If only one
display is specified, then a handball game is started.
Attention to the order of the options must be payed.
The gravity to use. In one and two player games, this is toward
the floor, and in the handball it is toward the paddle. Minimum
gravity for handball game is 0.1, and negative values are not
allowed, unlike in the other two modes. A synonym for the
switch is -g g
To use a net in the one or two player modes, use this switch.
The value of n must be 0>n>0.75. The net will be in the middle,
between the two players and when the ball hits it, it will
bounce back at full force. The maximum height, 0.75, is two
thirds of the height of the game arena. A synonym for this
switch is -n n The net option must not appear before the gravity
To use sound in the game, use this switch or it's synonym -s.
This must appear after the optional net switch.
The switches --noclick1 and--noclick2 mean that the specified player
need not to keep the mouse button 1 pressed down. Such options must
appear last on the command line. The key c can also be used to toggle
this while the game is running.
