Serendiep text adventure

Textadventure for Serendiep labyrinth, rewritten in c, using raylib to render in either a destop window or directly to a (DRM) framebuffer.

Dependencies:

• Raylib: https://www.raylib.com/
• Mini-XML: https://www.msweet.org/mxml/

Raylib is included as a submodule, the rest can be installed with:

sudo apt-get install libmxml-dev

To fetch or update the raylib code, after cloning or updating this repository run:

git submodule update --init

This will fetch the right version of raylib into the raylib subdirectory, updating or initializing it as needed.

Building

Compilation can be done as a single gcc command (after rayblib was already compiled). These commands are automated and documented in the Makefile.

For a full build you can run:

• make (or make drm) to get a direct framebuffer build. You typically run this on the rpi to run without a windowing system. Note that this does not do cross-compilation, it just selects the graphics output to use.
• make debug to get a framebuffer build with debugging symbols (i.e. for gdb debugging).
• make desktop to get a X/Wayland build to run on a normal PC. This build also includes debugging symbols.

These commands always do a clean rebuild of raylib. Once a full build was done, you can also build just the textadventure itself (avoiding a few seconds of raylib rebuild) with:

make textadventure

The output selection happens only in the raylib, so the textadventure build itself is identical regardless of the output selected.

Running

To run the game, run:

./textadventure

Note that the * key is used for the ⚛ key (which you might need in the game).

Debug mode

To run in debug mode, pass --debug on the commandline.

./textadventure --debug

Debug mode speeds up output generation for faster testing, and adds some commands.

To jump to a given scene:

go key_of_scene

To display all current state:

state

To eval an expression, for example to modify state:

eval name_of_var SET 1

Passing --debug also enables more log output.
