Canvas Engine

Description

Framework to create video games in HTML5 Canvas

Get Started

Follow the steps below to start:

  1. Download the code canvasengine-X.Y.Z.all.min.js on Github or this website
  2. Add this code in your page :

     <!DOCTYPE html>
     <script src="canvasengine-X.Y.Z.all.min.js"></script>
     <canvas id="canvas_id" width="640" height="480"></canvas>
    
  1. Initialize the canvas in your JS file :

     var canvas = CE.defines("canvas_id").ready(function() {    
    
     });
    

Method ready is called when the canvas is ready (DOM loaded)

Use development files

Development files allows you to improve or correct CanvasEngine. To do this, insert these two files:

    <!DOCTYPE html>
    <script src="core/engine-common.js"></script>
    <script src="canvasengine.js"></script>
    <canvas id="canvas_id" width="640" height="480"></canvas>

View other branches of CanvasEngine on Github, you'll other version under development

If you want to use features (Animation, Input, etc), add the appropriate files :

<script src="extends/Animation.js"></script>

If you develop or modify a feature, you can use the global variable Global_CE to use other features.

Example :

// In extends/your_feacture.js
Global_CE.Input.press(Input.Enter, function() {
});

Your code

Your code contains classe(s) :

Class.create("My_Class", {


});

The developer can use this class in his game. You can also add code like this:

var My_Class = {
    My_Class: {
        New: function) {
            return Class.New("My_Class");
        }
    }
};

it will use the namespace defined initially by the user :

var canvas = CE.defines("canvas_id").extend(My_Class).ready(function() {    
     canvas.Scene.call("MyScene");
});

canvas.Scene.new({
  name: "MyScene",
  ready: function(stage) {
     var foo = canvas.My_Class.New();
  }
});

Documentation

Try to properly document the code for developer :

/**
    @doc my_class
    @class Definition of "My Class"
    @example

        ...

*/
Class.create("My_Class", {

/**
  @doc my_class/
  @method foo ...
  @param bar {String} ...
  @example

        ...

*/
     foo: function(bar) {

     }

});
