Welcome to the Flash as a Gaming/Edu-Gaming Platform for the XO-1 project

XO-1 as a Target Platform for Flash Gamedev

  • With regards to performance as a Flash dev platform, it is pretty similar to a desktop with an AMD K6-2 450MHz CPU, 256MB RAM + Win98.
  • Again with performance, the XO-1 is more similar to a Flash Lite-enabled device than modern laptops
  • Because of the limited CPU & memory, application development methods will be very similar to producing content for Flash Lite which runs on devices with limited CPU & Memory.

As long as developers optimize their apps, the XO-1 is a good environment for Flash as a dev environment because of Flash's small CPU & memory footprint.

During testing, Flash Lite 2.0 content (which is based on Flash 7) ran pretty good on the XO -- performance was very similar to 330MHz Nokia S60 phones with the Adobe Flash Lite 2.0 player.

Gnash

  • The default installed Gnash has no sound (because Flash uses MP3s for sound and the default shipped Gnash comes compiled with MP3 libraries because of FOSS licensing restrictions)
  • The version of Gnash on 711 renders some AVM1 Actionscript 1.0/2.0 (Flash 8 & below) content wrong - will evaluate the version of Gnash that ships with 8.20. Testing 8.20 livecd ISO on a virtual machine showed that scripting is more accurate.
  • Gnash does not emulate the AVM2 (Actionscript Virtual Machine 2) found in Flash 9 and above.

This makes it a little less ideal target platform for OSS Flash dev -- the only *decent* production-level tools for FOSS flash dev requires using Actionscript 3 and only outputs Flash 9 AVM2 content (Flashdevelop + Flex SDK + JDK).

  • Doing further testing for compatibility of Flash Lite content. Flash Lite content uses AS 2.0 and is patterned after Flash 8 and below.

Official Adobe Flash Browser Plugin

Users may want to install the Adobe Flash browser plugin instead of Gnash which is packaged by default.

Adobe Flash on Opera

When we installed Opera 9.52 (desktop version runs w/o a hitch on the XO aside from needing to launch it from the terminal), it ran even better -- Flash performance in Opera is much better than in the XO's default Browser.

Opera therefore, is an ideal environment to do Flash content on for the XO-1. (or perhaps Firefox 3? Still need to test out FF3).

OLPC Skin for Opera:

Beause of a conflict with the Rainbow security and Sugarization, Opera 9.52 has to be run from the terminal. Open up the terminal then type 'opera'

What's needed:

  • A new Sugarized Activity icon that does not conflict with the XO's Rainbow security
  • An Activity icon to launch the browser with specific local html as the default content as a method for launching flash apps.

General Installation

Installing by .rpm file

Open your terminal activity on the Activity panel below your Sugar desktop or press Ctrl+0

Type the following commands: 

su
wget <url of rpm file to be downloaded>
rpm -vi <rpm file>
exit
