Usage

Sample code

Install plugin

Load minify file

  • Load plugin (minify file) in preload stage
    scene.load.plugin('rexlzstringplugin', 'https://raw.githubusercontent.com/rexrainbow/phaser3-rex-notes/master/dist/rexlzstringplugin.min.js', true);
    
  • Add lz-string object
    var lzstring = scene.plugins.get('rexlzstringplugin').add(config);
    

Import plugin

  • Install rex plugins from npm
    npm i phaser3-rex-plugins
    
  • Install plugin in configuration of game
    import LZStringPlugin from 'phaser3-rex-plugins/plugins/lzstring-plugin.js';
    var config = {
        // ...
        plugins: {
            global: [{
                key: 'rexLZString',
                plugin: LZStringPlugin,
                start: true
            },
            // ...
            ]
        }
        // ...
    };
    var game = new Phaser.Game(config);
    
  • Add lz-string object
    var lzstring = scene.plugins.get('rexLZString').add(config);
    

Import class

  • Install rex plugins from npm
    npm i phaser3-rex-plugins
    
  • Import class
    import LZString from 'phaser3-rex-plugins/plugins/lzstring.js';
    
  • Add lz-string object
    var lzstring = new LZString(config);
    

Create instance

var lzstring = scene.plugins.get('rexLZString').add({
    // encoding: 'none'     // 'none'|0, 'base64'|1, 'utf16'|2, 'uri'|3
});
  • encoding :
    • 'none', or 0 : no encoding.
    • 'base64', or 1 : base64 encoding.
    • 'utf16', or 2 : UTF16 encoding.
    • 'uri', or 3 : URI encoding.

Compression

var compressionResult = lzstring.compress(src);

Decompression

var decompressionResult = lzstring.decompress(compressionResult);

Set encoding

lzstring.setEncoding(m);  // 0|'none'|1|'base64'|2|'utf16'|3|'uri'
