poly

Amber Smalltalk demo with polygons and a physics simulator.

Warning: Barely working naugthy code hacked in minutes before a screencast! Plus some community help. Sharing because it might have educational value

Prerequisites

You need to have installed nodejs then Amber. Note that newer versions of nodejs includes the node package manager npm, so you can get amber with:

# Installs Amber's command line interface (global install, needed only once)
npm install -g amber-cli

or

sudo npm install -g amber-cli

Once you have the Amber Smalltalk command line interface you can start your new Amber projects with this:

mkdir myapp
cd myapp
amber init myapp
amber serve

Installing poly locally

1. In your git root directory do:

       git clone https://github.com/sebastianconcept/poly
       cd poly
       bower install
       amber serve

2. Point your web browser to localhost:4000 [1]

3. Click on add things [2]

4. Add motion to things

5. Add gravity

6. Open Helios or legacy IDE

7. The code is in the Poly package

[1] If, for any reason, you don't have port 4000 available you can start amber with amber serve --port 3000

[2] The Add things button didn't add a polygon? That's because of a bad random number combination. Just bad luck! Click again until your 4 random numbers can form a closed polygon and I promise it will add things :)

Notes

1. The file bower.json contains the dependancy on http://wellcaffeinated.net/PhysicsJS/. Thus bower install pulls in this JavaScript framework.

2. This project shows how a third party JavaScript library is used in Amber Smalltalk. You can see how is loaded in the index.html file.
