F-L-Undead, let's put it this way: if you don't use "synchronized" on those methods, then you're messing with forces you don't understand :) It will probably work most of the time, but sometimes, just occasionally, it will go mysteriously wrong... unless you use "synchronized". You don't have to understand what it does, and you don't have to use it in your own code; just in the two methods in ScrollingListener.

You can't do that exactly in Java. You have a few options: First option: store the values in a HashMap eg: <Code Omitted> For this to work you'll need to import the HashMap class at the top of your class: <Code Omitted>

It's more or less just a experiment for this Kinect. the minigames i have in greenfoot and it's fine there. I just tried to expand the kinect with all my other stuff in Netbeans. And it's not toally out of greenfoot, still using the same classes system and library. I just try to run it without an additional software this time.

Hi, I saw this message today: "unmappable character for encoding UTF8" I run greenfoot on ubuntu 11.04. It was a class that had some strange characters in a comment (this hapened because of changing computers, and i write in portuguese with accents). I fixed it and it executed as usual.

You can measure the speed yourself using System.currentTimeMillis() - it returns (as a "long") the number of milliseconds since 1 January 1970. You can simply print it to the terminal each act() and then calculate the difference by hand.

Thanks davmac; I appreciate your input. May God shower you with blessings!!

thanks so much

use the following code: <Code Omitted> now in the part where you set the Rotation, you may have to add or subtract 90, and remove the negative or something, because that depends on the rotation of your object.

If you could give me any advice on how to improve the scenario, it would be much appreciated! http://www.greenfootgallery.org/scenarios/3081

Ahh ok! Sry, I haven't seen this Method. xD Thank you very much!
