This code is built upon the offline version of the app, so it doesn’t have web tiles support and the mapView cannot be created in xml (these can be changed easily by following the previous two tutorials).

The code isn’t perfect either, it does the job though 🙂 .

Before I talk too much, here see the results for yourself, this is the web version :  SpringLab Web Version.

Reminds you of World of Goo 😀 ?

I came across this tutorial, from which I learned this lovely vector equation:

 F = -k(|x|-d)(x/|x|) - bv

I applied it to 2D springs and it gave amazing results especially when Read more…
