My name is Lorin Beer, and I am the creator and primary developer of the Pender project. I was recently contacted by one Mr. WINK on the forums here concerning the dismal shape of the current GIT repo.
Please stay tuned, I am currently out on sick leave, but have been hacking on Pender.
A little about Pender:
Pender Android uses Rhino, a Java JS engine by Mozilla for fast js processing. The demo code in the downloads section of github shows a simple render stress test, with 40+ individual sprites rendering at 35+ FPS on a Galaxy Nexus device.
However, working with the Uxebu boys and bonsai.js, we noticed an unacceptable slowdown when processing js calls to a <scarequote> realistic </scarequote> js codebase. The reason for this is simple: Rhino produces jvm bytecode for optimization, but that fails when running on a dalvyk java environment.
So, the latest move is to replace Rhino with V8. Please expect an update to the git repo in the next few days. I'll update it with the dev code on my machine, as well as (working) build instructions.
Thanks for the interest and stay tuned!
