SWF translator

An attempt to emulate SWF in HTML5 environment. WebGL2 is required.

Usage

Requirement:

• NodeJS >= 12

Build source code:

yarn install
yarn build

Translate SWF tags:

node packages/swf-translator/dist/index.js build-swf <path to swf> <output directory>

Translate AS3 source code:

node packages/swf-translator/dist/index.js build-as3 <AS3 source directory> <output directory>

Assembly required to run the output, some hints:

• Alias swf-lib in output source code to the compiled swf-lib package.
• Bundle character definition JSON: JSON.stringify the variable bundle in character index.js.
• Construct asset manifest:

  {
    "data": "data",
    "properties": {}, // embed properties.json
    "assets": {
      "data": {
        "url": "./data.json", // path to bundled character definition JSON
        "size": 0, // zero if no need of progress report
      },
      "character1": {
        "url": "./character1.png",
        "size": 0,
      }
      // etc.
    }
  }

• Start the SWF:

  import lib from "swf-lib";
  const manifest = { /* ... */ };
  const library = await lib.__internal.loadManifest(manifest);
  const stage = new lib.flash.display.Stage(library.properties);
  stage.__withContext(() => stage.addChild(library.instantiateCharacter(0)))();
  document.body.appendChild(stage.__canvas.container);
