Java would be a great addition in my opinion :D At my sixth form college, if you study IB (international baccalaureate) Computer Science, you use Java in the IDE's NetBeans, BlueJ and Greenfoot, which in my opinion (as a student of the course) its a great system. Our A level Computing students have to use Visual Basic though (poor them...)

Self-answer, persistence and experimentation pays off! Since the PacMan could not find the net.java.games.input, but I saw it there, I decided to just replace the gamepadlib folder with the one from the GamePadTester which did work. This solved the recognition problem. Then there were two methods in PacMan that were improperly overriding the move method by narrowing the access from public to private, so I changed them to public. Then, it worked! So, copy the gamepadlib folder from GamePadTester on top of the PacManGamePad folder. And, don't forget to rename the jinput-dx8_64 to j

Blight, if you need more help, you should post some code to show what you have and what you're having trouble with. The question is way too general otherwise.

Thats Builder boy that the trick. and thanks for the refernce as Im only using greenfoot to learn java.

Well, how does the code keep track of the position within the world (i.e. the amount the background has scrolled)? I'm not looking at the code right now, but I assume there is some variable somewhere which tracks this?

THANK YOU!!!!!!! I noticed the issue with the WestboundAuto class. The new Road() solved the issue.

What is line 33 in your last code post?

There have been some discussions on this topic already. http://www.greenfoot.org/topics/618 http://www.greenfoot.org/topics/656 http://www.greenfoot.org/topics/668 Just a few I spotted reviewing previous ones.

just saying but i did that crab crab thing u said and it didnt work so i left my world class the same so the last thing you said i would have to do in order for it to have the right score correct and if so heres my code because when i put in c.getValue() it didnt work said something about not knowing what c is and im still lost on Counter c = w.getCounter(); where would i put that ? like whats confusing me is after you put in a method like: public int getScore() 09.{ return score; } //Then to get the score, you do: c.getScore(); would i put c score in with the rest or what?

Yeah I do this quite often, and its always worked for me

What you're describing is part of the built in swing classes that are the default UI building toolkit for standard Java programs (at least until Java 8!) The popups are easy to use but as already pointed out they're annoying, look very separate from the Greenfoot scenario and in many browsers the warning triangle that pops up by them to warn you that they're part of an applet can make users a bit suspicious that something else is going on! I've used them a few times but usually changed them to something else later, they might be good as a quick hack but I wouldn't recommend using them perma

Just to add to this, you can assign an alpha value to your new color. The color constructor new color(float r, float g, float b, float a) does this. Greenfoot.getRandomNumber returns an int, but it should be converted to a float in the color constructor. If not, it's an easy fix. Change your color constructor to this. <Code Omitted>

Have a look at http://www.greenfoot.org/scenarios/3767 - that's how I do it

:L I didn't know that, having never read the documentation myself... looks useful though
