Taxman Wasm

This is the Taxman Engine running in your browser.

The purpose of this project is to help me learn Wasm, as well as allow me to join game jams with Playdate games all the while allowing everyone to play even if they do not own the console.

Online demo is available here.

Requirements

1. For compiling, Emscripten needs to be installed and in PATH
2. make is used as the build tool
3. The example uses Python 3 for serving the page locally. Any other means of setting up a server is equally adequate
4. To update the image assets, the Pillow library for python is required

How to run

Make sure you have the submodule checked out.

Run in command line:

make
cd docs && python -m http.server

Then open a browser and head to http://localhost:8000

How to build

When developing a game, new assets and code directories can be added to the project using the provided scripts.

To update the makefile with the new code directories, run

bash scripts/update_project.sh

To build the game, run

make

This requires python and the Pillow library, which can be installed by running

python -m pip install pillow

Building the game will move all required files into the ´docs´ directory, which can then be served e.g. using the example method shown in the example.

The gecko demo that comes with the repository should be directly runnable by itself.

Features

• Runs games built with Taxman Engine in browser
• Rendering the display
• Mapping of keys
• Crank controls mapped to keys
• Load asset files from server
• Amazing console visualisation
• Works on most mobile devices (i.e. smartphones)

How to create a game

All game code is in the game directory. Custom scenes, game objects and game object components are added there. The first scene is creted in main.c, and passed to the game_init function. Examples of loading assets, creating game objects, changing scenes, and more can be found in loading_scene.c and gecko_scene.c.

Assets live in the assets directory and are moved to docs from there. Subdirectories of assets will be automatically turned into sprite sheets which the engine can read.

Rough Backlog

• Audio
• Migrate to SDL2 if it can be made more performant than SDL1
