Usage of Planck.js with TypeScript (Planck.js is a port of Box2D Physics Engine)

My example shows how to use Ammo.js with TypeScript in Debug and Release modes: hello-planckjs-webgl10-ts

You should install these modules globally:

• npm i typescript -g
• npm i browserify -g
• npm i uglify-js -g

Install all packages from `package.json` using the command: `npm i`

Comment/Uncomment Debug/Release in `index.html` and `main.ts` (see comments in these files).

Use these commands to build the example:

• `npm run debug` - to set breakpoint in code editors and to publish on PlayGround (like Plunker), for example: Hello Planck.js. WebGL 1.0, TypeScript
• `npm run release` - to bundle in `bundle.min.js` for production

Note. See also: Usage of Ammo.js with TypeScript (Ammo.js is a port of Bullet Physics Engine)
