I saw you doing this in your code: [code]World world; world = getWorld(); world.dosomething;[/code] This could be better by doing this: [code]getWorld().dosomething;[/code] This uses less memory, because we're not creating variables that have to be stored in your memory. It wouldn't be that much code that you use less when you do it on my way, but it's always better to don'use more memory than you need to. I hope this helps.
