It should compile on different platforms because it uses SDL library as backend.

Installation:

To install run such sequence of commands:

make - Compiles library and tests

make install - Installs library and tests

Automanic is an vehicular deathmatch game.

Automanic is a vehicular deathmatch game, hopefully becoming the best of Twisted Metal, Interstate 76, the Burnout Games, and Carmageddeon, focussing on cross-country carnage. It uses Crystal Space, CEL, and ODE.

Games::Go::Dg2PDF is a Perl extension to convert Games::Go::Diagrams to PDF (Portable Document Format).

SYNOPSIS

use Games::Go::Dg2PDF
my $dg2pdf = B convertDiagram($diagram);

A Games::Go::Dg2PDF object converts a Games::Go::Diagram object into a PDF file.

Games::Go::Dg2Mp is a Perl extension to convert Games::Go::Diagrams to John Hobbys MetaPost (which is adapted from Donald Knuths Metafont).

SYNOPSIS

use Games::Go::Dg2Mp
my $dg2mp = B convertDiagram($diagram);

A Games::Go::Dg2Mp object converts a Games::Go::Diagram object into a TeX (.tex) and a MetaPost (.mp) file. The MetaPost file contains figures for each of the diagrams and overstones required to make the complete game diagram.

Running MetaPost (mpost or possibly mp) on the .mp file creates a set of figure files, each of which is an Encapsulated PostScript figure. Running TeX (tex) on the .tex file creates a .dvi file which tries to include the Encapsulated PostScript figures. Running dvips on the .dvi file (from TeX) creates the final PostScript (.ps) file containing the complete game diagram.

See man mpost (or possibly man mp) for more details of the overall MetaPost system and environment.

Games::Go::Dg2TeX is a Perl extension to convert Games::Go::Diagrams to TeX.

SYNOPSIS

use Games::Go::Dg2TeX
my $dg2tex = B convertDiagram($diagram);

A Games::Go::Dg2TeX object converts a Games::Go::Diagram object into TeX source code which can be used stand-alone, or it can be incorporated into larger TeX documents.

Eclipse is a set of C++ classes designed to give beginner developers a head start in developing their first games as well as more experienced developers who dont want to have to write code for mundane tasks like fonts, sprites, and image loading.

Eclipse 2D Game Engine provides bitmap fonts, window management, audio capabilities, image loading, error logging, and zip file support.

Games::Irrlicht is a Perl module that use the Irrlicht 3D Engine in Perl.

SYNOPSIS

package MyGame;
use strict;

use base Games::Irrlicht;

use Games::Irrlicht::Constants; get EDT_SOFTWARE etc

# override methods:

The Why

When building a game or screensaver displaying some continously running animation, a couple of basics need to be done to get a smooth animation and to care of copying with varying speeds of the system. Ideally, the animation displayed should be always the same, no matter how fast the system is.

This not only includes different systems (a PS/2 for instance would be slower than a 3 Ghz PC system), but also changes in the speed of the system over time, for instance when a background process uses some CPU time or the complexity of the scene changes.

In many old (especial DOS) games, like the famous Wing Commander series, the animation would be drawn simple as fast as the system could, meaning that if you would try to play such a game on a modern machine it we end before you had the chance to click a button, simple because it wizzes a couple 10,000 frames per second past your screen.

While it is quite simple to restrict the maximum framerate possible, care must be taken to not just "burn" surplus CPU cycles. Instead the application should free the CPU whenever possible and give other applications/thread a chance to run. This is especially important for low-priority applications like screensavers.

Games::Irrlicht makes this possible for you without you needing to worry about how this is done. It will restrict the frame rate to a possible maximum and tries to achive the average framerate as close as possible to this maximum.

Games::Irrlicht also monitors the average framerate and gives you access to this value, so that you can, for instance, adjust the scene complexity based on the current framerate. You can access the current framerate, averaged over the last second (1000 ms) by calling current_fps.

Frame-rate Independend Clock

Now that our application is drawing frames (via the method draw_frame, which you should override in a subclass), we need a method to decouple the animation speed from the framerate.
If we would simple put put an animation step every frame, we would get some sort of Death of the Fast Machine" effect ala Wing Commander. E.g. if the system manages only 10 FPS, the animation would be slower than when we do 60 FPS.

To achive this, SDL::App::FPS features a clock, which runs independed of the current frame rate (and actually, independend of the systems clock, but more on this in the next section).
You can access it via a call to current_time, and it will return the ticks e.g. the number of milliseconds elapsed since the start of the application.

To effectively decouple animation speed from FPS, get at each frame the current time, then move all objects (or animation sequences) according to their speed and display them at the location that matches the time at the start of the frame. See examples/ for an example on how to do this.

Note that it is better to draw all objects according to the time at the start of the frame, and not according to the time when you draw a particular object. Or in other words, treat the time like it is standing still when drawing a complete frame. Thus each frame becomes a snapshot in time, and you dont get nasty sideeffects like one object beeing always "behind" the others just because it gets drawn earlier.

Time Warp

Now that we have a constant animation speed independend from framerate or system speed, lets have some fun.

Since all our animation steps are coupled to the current time, we can play tricks with the current time.

The function time_warp lets you access a time warp factor. The default is 1.0, but you can set it to any value you like. If you set it, for instance to 0.5, the time will pass only half as fast as it used to be. This means instant slow motion! And when you really based all your animation on the current time, as you should, then it will really slow down your entire game to a crawl.

Likewise a time warp of 2 lets the time pass twice as fast. There are virtually no restrictions to the time warp.

For instance, a time warp greater than one lets the player pass boring moments in a game, for instance when you need to wait for certain events in a strategy game, like your factory beeing completed.

Try to press the left (fast forward), right (slow motion) and middle (normal) mousebuttons in the example application and watch the effect.

If you are very bored, press the b key and see that even negative time warps are possible...

Ramping Time Warp

Now, setting the time war to factor of N is nice, but sometimes you want to make dramatic effects, like slowly freezing the time into ultra slow motion or speeding it up again.

For this, ramp_time_warp can be used. You give it a time warp factor you want to reach, and a time (based on real time, not the warped, but you can of course change this). Over the course of the time you specified, the time warp factor will be adapted until it reaches the new value. This means it is possible to slowly speeding up or down.

You can also check whether the time warp is constant or currently ramping by using time_is_ramping. When a ramp is in effect, call ramp_time_warp without arguments to get the current parameters. See below for details.

The example application uses the ramping effect instead instant time warp.

Event handlers

This section describes events as external events that typically happen due to user intervention.
Such events are keypresses, mouse movement, mouse button presses, or just the flipping of the power switch. Of course the last event cannot be handled in a sane way by our framework.

All the events are checked and handled by Games::Irrlicht automatically. The event QUIT (which denotes that the application should shut down) is also carried out automatically. If you want to do some tidying up when this happens, override the method quit_handler.

The event checking and handling is done at the start of each frame. This means no event will happen while you draw the current frame. Well, it will happen, but the action caused by that event will delayed until the next frame starts. This simplifies the frame drawing routine tremendously, since you know that your world will be static until the next frame.

Games::Bingo::Column is a Perl module with a column class used for generating bingo cards.

SYNOPSIS

my $c = Games::Bingo::Column-E< gt >new();

foreach my $number(@numbers) {
$c-E< gt >populate($number);
}

my @numbers = qw(1 2 3 4 5 6 7 8 9);

my $c = Games::Bingo::Column-E< gt >new(@numbers);

my $number = $c-E< gt >get_highest_number();

The Column is used when building the bingo cards and is a temporary data structure.

The class has two attributes:

_array
_array is a list of numbers for containment in the class, since the class actually is nothing but an array with a status flag.
label

The label being the group to which the numbers in the array belong.
