Minecraft Player updated for alternativa 8

I haven’t had much time to experiment with the new updates coming from alternativa3d, what with moving to another country and the various projects i’m involved with i just haven’t had time. Now i’ve started to settle in, it seems like a good a time as any to get back on and try some things out. First up i thought i would ease back in and just update my flash minecraft player to alternativa version 8.17 making use of the gpu support in flash player 11 and also trying out the new syntax and class changes. It turned out pretty well but I was a little disappointed at not being able to recreate the pixel like effect the textures have last time. For some reason in version 8 the textures are smoothed without a way to change it, perhaps its just a result of using the gpu I’m not sure, either way its still faster and using less resources than the previous version.
This time I separated the minecraft player into a separate “Player” class just so its a tiny bit cleaner. Here is the Character.as class, note that the new version 8 is slightly different in that it calls upon the stage3d and uploads resources to it to make use of the gpu rendering i mentioned earlier.
