  I dreamed the other night about how will it be to have the space invaders inside a normal sheet of paper and this is what was brought to life:

  This movie requires Flash Player 9

  How to play:
  C for insert coin
  1 for player 1
  2 for player 2
  R Resets the game
  Backspace Tilts the emulator (game over if someone kicks the machine )

  Tech stuff to create the skin:
  - Created a SimpleSkin implementing the ISkin interface that uses the graphics of a sprite to paint only the active pixels (and not the background) ( SimpleSkin.as )
  - Extended the SimpleSkin and added a paper background the sprite and voila! ( PaperSkin.as )

  Everything is updated on the github repository:

  http://github.com/ozipi/As3_SpaceInvaders_Emulator

  The whole paper invaders is dedicated to Mike Chambers (@mesh), i bet that he would love to have Paper Invaders when he was a child : )

  As3 Space Invaders Emulator For Dummies (Source code)

  “You have to wanna make something, so if there is not something wanna make then there is not much you can do to make somebody else to make something.”
  Chaosradio international 2007 podcast
  Bre prettis

  How to play:
  C for insert coin
  1 for player 1
  2 for player 2
  R Resets the game
  Backspace Tilts the emulator (game over if someone kicks the machine )

  This movie requires Flash Player 9

  Code Features:
  - Logic separated on the intel 8080 from the actual implementation of the Space invaders emulator, this was intented to have a separated class that only has intel 8080 logic and could be used/extended/improved and anyone want to use it for another project/emulation/cool shit (doug mccune magic word!)
  - Added a Skin interface in order to have the ability to implement any kind of video screen and not just only a bitmap for the classic one (examples of this will come later in future posts)
  - Added plenty of comments (not to all functions you will see why )
  - Created statically the opcode table function dictionary instead of dinamycally

  Long boring story:
  A few months ago i saw that tibo (Thibault Imbert http://www.bytearray.org/ ) released a space invaders arcade emulator, i remember that i told my coworkers “holy shit this guy is awesome”, we took a peek inside the code and as soon we touch the intel 8080 we were like O_o what the….., we thought that it was very complicated (but we never try to play with it),a few days ago i tried to reproduce and see how difficult it would be to code it from the beggining (it took me 5 days) to have the projected recoded following the tibo code logic guidelines (i had to use some hex comparing sentences because of a ugly bug) and the blitz tutorial giving birth to the my own space invaders emulator n_n.

  Source code:
  The code is released under the MIT license and is alocated in github where you can download/fork/see it

  http://github.com/ozipi/As3_SpaceInvaders_Emulator

  Intel 8080 General explanation ( http://www.cpu-world.com/Arch/8080.html | http://en.wikipedia.org/wiki/Intel_8080)

  On future posts i’ll try to explain it in a easy way for the people that has never touch any binary code with the byte arrays or has some trouble trying to imagine how to code an emulator (like a was a week before), so as3 experts please be patient :p

  Thanks to Thibault Imbert (same guy from the wiiflash project), Remi Veilleux, and the guys that posted the specifcations, i have learned a lot on how to use the bytearrays and the bitwise operators and how the interpreted emulation works in general.

  Get some fun!

  git/svn info on your bash prompt (oziputils)

  ozipi 12:46 am on November 14, 2009 | 1 Permalink | Reply
  Tags: bash, git (2), github (2), oziputils, svn

  History
  yesterday i came across this bash script (http://hocuspokus.net/2009/07/add-git-and-svn-branch-to-bash-prompt) then while eating a couple scramble eggs at 4 am i thought that i would be a little bit nicer if i could include the SVN revision number to the script, i took me a couple hours to get it done (sed/awk biatches!) but i did it on the end

  How does it work
  just enter to any checkout of SVN or a clone of any GIT project, and your prompt will indicate the type of version control and the current branch and also the current revision number (revision will be only on the SVN info)

  Git
  
  
  
  
  SVN

  
  
  

  
  

  Download/Source
  download the file from the oziputils github project

  http://github.com/ozipi/oziputils

  or just grab whatever the functions and the PS1 export from the source and put it on your .profile file

  Flash panel snippets collection

  ozipi 10:04 am on November 5, 2009 | 1 Permalink | Reply
  Tags: as3 (3), code (2), flex

  After taking a look to the flash snippets panel from lee brimelow i thought that it would be nice to have a snippet common-share-place, then i just created an svn repo on google code, so everybody can take a look on it and upload/modify any of the scripts uploaded

  For the time being i only created AS3 snippets for simple tasks like adding sections to a class, getter and setters, the most used overrides (for me :p), creating private functions and that kind of stuff

  Flash snippets repository info:
  http://code.google.com/p/flash-panel-snippets/

  zip file for the lazy ones:
  snippets.zip
  

  Installing the snippets:
  - Download the svn files or the zip file
  - Go to your current flash builder/eclipse workspace directory and you will find your current snippets inside the currentworkspacedirectory/.metadata/.plugins/Flash_Snippets/snippets
  - Copy any snippet you like to the current directory

  Next steps:
  - Create spark mxml snippets
  - Add a cool logo : )

  Want to Add/Fix any snippet? please feel free to do it directly to the svn or to drop a comment (or just send a /slap )

    Nunca he podido fotografiar un ave-base (base de beisbol), o sea, de esas que se te “aparecen” cuando “tocas base”. No se dejan, la cámara falla o el ave se esconde. Tú me entiendes, ozo.
