Partial Pygame port to the Skulpt implementation of Python

Pygame module for Skulpt

An example of the module can be found on http://petlja.github.io/pygame4skulpt.

How to use

In order to use the module, you will probably want to have files served by a http server as in run-example.sh and run-example.bat. Our Pygame module can be imported as follows:

    var basePath = 'pygame/';
    Sk.externalLibraries = {
        'pygame': {
            path: basePath + '__init__.js',
        },
        'pygame.display': {
            path: basePath + 'display.js',
        },
        'pygame.draw': {
            path: basePath + 'draw.js',
        },
        'pygame.event': {
            path: basePath + 'event.js',
        },
        'pygame.font': {
            path: basePath + 'font.js',
        },
        'pygame.image': {
            path: basePath + 'image.js',
        },
        'pygame.key': {
            path: basePath + 'key.js',
        },
        'pygame.mouse': {
            path: basePath + 'mouse.js',
        },
        'pygame.time': {
            path: basePath + 'time.js',
        },
        'pygame.transform': {
            path: basePath + 'transform.js',
        },
        'pygame.version': {
            path: basePath + 'version.js',
        },
    };

Base path should correspond to the location where you put the Pygame module. A CDN version can be found at https://cdn.rawgit.com/Petlja/pygame4skulpt/3435847b/pygame/init.js.

API

Sk.main_canvas

Since the Pygame module relies heavily on the graphics and event handling, we provide several functionalities for communicating with the module. First and the most important one is registering your canvas. Basically, Pygame module needs to have a reference to the canvas to be used for rendering graphics. In order to register your canvas, use the following:

Sk.main_canvas = document.createElement("canvas");

or

Sk.main_canvas = document.getElementById("myCanvas");

Sk.insertEvent

Pygame module has mouse and keyboard event listeners added to canvas and window. If you want to have an additional way of inserting the events (eg. you want to add the arrows that create keydown events) you can use Sk.insertEvent function as follows:

Sk.insertEvent("left");

Currently, the only supported events are:

• "up" corresponding to KEYDOWN event with K_UP key.
• "down" corresponding to KEYDOWN event with K_DOWN key.
• "right" corresponding to KEYDOWN event with K_RIGHT key.
• "left" corresponding to KEYDOWN event with K_LEFT key.
• "quit" corresponding to QUIT event with K_ESCAPE key.

Sk.title_container

If you want to have an element where the title is going to be shown, make use of the following:

Sk.title_container = ...

Sk.quitHandler

After running the Pygame code, you want to make sure that everything got cleaned up. For that reason, there exists Sk.quitHandler which gets called by pygame.quit() method. An possible example is:

Sk.quitHandler = function () {
    $('.modal').modal('hide');
};
