Hello everybody, I am making a game for my final project and one of the requirements is to add the score to an external file. I browsed green foot forums and the best I found is the UserInfo Greenfoot API http://www.greenfoot.org/files/javadoc/greenfoot/UserInfo.html where you can save a score. Here is where the saving to an external source comes in, I want to instead save into some kind of online form ( Like an excel sheet ) where I can then go through the values column by column and row by row and display the best scores. Would that be possible? Because if I were to use something like the read and write methods provided by Java the user would then have to upload it somehow for it to show up for everyone else. Just as a recap I need to somehow save a name and a score in some kind of form that then can be accessed by anyone with the greenfoot file. ( Sorry for my bad english )

This only happens sometimes, but after a bullet hits an asteroid it creates Debris. That Debris later has a randomly generated decay and is destroyed after the decay timer is up as seen on line 27 My question to you is why does it only randomly choose to give a NullPointerException and how do I fix it? <Code Omitted> Another question I have about the code is the turn / setRotation functions. Whenever the debris is generated, it is given a random rotation and then turned towards it. For some reason it only ends up having 8 or so different rotations visible as shown here <Image Omitted> And I am wondering if there is anyway I can make it have more possible outcomes. Or is this due to the object being so small? (2x2 pixels) Edit: took out the code for generating sound as that was copied by mistake

Hi all, I am delivering a Games Development Unit to HND students next semester and was wondering if there were any teaching resources available focussed on Greenfoot as the game development environment? Thanks in advance for your help. Mike
