NAME

TCOD - FFI bindings for libtcod

SYNOPSIS

    use TCOD;
    use File::Share 'dist_file';

    use constant {
        WIDTH  => 80,
        HEIGHT => 60,
    };

    my $tileset = TCOD::Tileset->load_tilesheet(
        dist_file( TCOD => 'fonts/dejavu10x10_gs_tc.png' ),
        32, 8, TCOD::CHARMAP_TCOD,
    );

    my $console = TCOD::Console->new( WIDTH, HEIGHT );

    my $context = TCOD::Context->new_terminal(
        WIDTH, HEIGHT, tileset => $tileset,
    );

    while (1) {
        $console->clear;
        $console->print( 0, 0, 'Hello World!' );
        $context->present( $console );

        my $iter = TCOD::Event::wait;
        while ( my $event = $iter->() ) {
            exit if $event->type eq 'QUIT';
        }
    }

DESCRIPTION

TCOD offers Perl bindings to libtcod, a library for developing roguelike games.

On Stability

This distribution is currently experimental, and as such, its API might still change without warning. Any change, breaking or not, will be noted in the change log, so if you wish to use it, please pin your dependencies and make sure to check the change log before upgrading.

ENUMS

The enums listed below are available as constants like the ones defined using constant, which means the same caveats apply here.

To provide introspection into the values of the enums, they are also made available as package variables with the names of each enum. This makes it possible to get the name of a value in a given enum with code like the following:

    say $TCOD::Alignment{ TCOD::LEFT }; # Prints 'LEFT'

Alignment

  • TCOD::LEFT

  • TCOD::RIGHT

  • TCOD::CENTER

Renderer

  • TCOD::RENDERER_GLSL

  • TCOD::RENDERER_OPENGL

  • TCOD::RENDERER_SDL

  • TCOD::RENDERER_SDL2

  • TCOD::RENDERER_OPENGL2

  • TCOD::NB_RENDERERS

BackgroundFlag

This flag is used by most functions that modify a cell background color. It defines how the console's current background color is used to modify the cell's existing background color.

See the documentation for TCOD::Color for details on how color arithmetic works when referenced below.

When equations are listed below, these are applied to each individual component in turn, with new being the component for the new color, old being the one for the current one, and white standing in for the maximum value for a color component (255).

  • TCOD::BKGND_NONE

    The cell's background is not modified.

  • TCOD::BKGND_SET

    The cell's background is replaced with the new color.

  • TCOD::BKGND_MULTIPLY

    The cell's background is multiplied with the new color.

  • TCOD::BKGND_LIGHTEN

    Each of the components of the cell's background is replaced with the respective component of the new color if it is lighter.

  • TCOD::BKGND_DARKEN

    Each of the components of the cell's background is replaced with the respective component of the new color if it is darker.

  • TCOD::BKGND_SCREEN

    The cell's background color is modified according to the following operation:

        white - ( white - old ) * ( white - new )
  • TCOD::BKGND_COLOR_DODGE

    The cell's background color is modified according to the following operation:

        new / ( white - old )
  • TCOD::BKGND_COLOR_BURN

    The cell's background color is modified according to the following operation:

        white - ( white - old ) / new
  • TCOD::BKGND_ADD

    The new color is added to the cell's background.

  • TCOD::BKGND_ADDALPHA

    Use this as a macro with a float parameter between 0 and 1. The cell's background color is modified according to the following operation:

        old + alpha * new
  • TCOD::BKGND_BURN

    The cell's background color is modified according to the following operation:

        old + new - white
  • TCOD::BKGND_OVERLAY

    The cell's background color is modified according to the following operation:

        2 * new * old                                 # if the component is >= 128
        white - 2 * ( white - new ) * ( white - old ) # if the component is <  128
  • TCOD::BKGND_ALPHA

    Use this as a macro with a float parameter between 0 and 1. The cell's background color is modified according to the following operation:

        ( 1 - alpha ) * old + alpha * ( new - old )
  • TCOD::BKGND_DEFAULT

    Use the console's default background flag. See TCOD::Console::set_background_flag.

Distribution

These values are used by TCOD::Random to generate random numbers.

  • TCOD::DISTRIBUTION_LINEAR

    This is the default distribution. It will return a number from a range min-max. The numbers will be evenly distributed, ie, each number from the range has the exact same chance of being selected.

  • TCOD::DISTRIBUTION_GAUSSIAN

    This distribution does not have minimum and maximum values. Instead, a mean and a standard deviation are used. The mean is the central value. It will appear with the greatest frequency. The farther away from the mean, the less the probability of appearing the possible results have. Although extreme values are possible, 99.7% of the results will be within the radius of 3 standard deviations from the mean. So, if the mean is 0 and the standard deviation is 5, the numbers will mostly fall in the (-15,15) range.

  • TCOD::DISTRIBUTION_GAUSSIAN_RANGE

    This one takes minimum and maximum values. Under the hood, it computes the mean (which falls right between the minimum and maximum) and the standard deviation and applies a standard Gaussian distribution to the values. The difference is that the result is always guaranteed to be in the min-max range.

  • TCOD::DISTRIBUTION_GAUSSIAN_INVERSE

    Essentially, this is the same as TCOD::DISTRIBUTION_GAUSSIAN. The difference is that the values near +3 and -3 standard deviations from the mean have the highest possibility of appearing, while the mean has the lowest.

  • TCOD::DISTRIBUTION_GAUSSIAN_RANGE_INVERSE

    Essentially, this is the same as TCOD::DISTRIBUTION_GAUSSIAN_RANGE, but the min and max values have the greatest probability of appearing, while the values between them, the lowest.

SHARE DATA

This distribution bundles some data to make development simpler.

You can make use of this data with a distribution like File::Share, like in this example:

    use File::Share 'dist_file';
    my $path = dist_file TCOD => 'fonts/dejavu10x10_gs_tc.png';

The fonts directory contains antialiased fonts that can be used with TCOD. The names of the font files are of the form:

    <font_name><font_size>_<type>_<layout>.png

    <type>   : aa 32 bits png with alpha channel
               gs 24 bits or greyscale PNG

    <layout> : as standard ASCII layout
               ro standard ASCII layout in row
               tc TCOD layout

The terminal8x8 font is provided is every possible format as en example.
