So if I use for example getWorld().removeObjects(java.util.Collection<? extends Actor> objects), I have to first create a list of objects?
Yes. Find an additional method among those provided.

Is there a way to do a method like that though or should I use a way from above?
It is possible, but you may still have to modify the act method due to the removal of the actor from the world. The code would still be like what I gave above with the modified line 7-- probably with and 'else if' for initiating the timer.

Gamepad Help

By BluRogue714, with no replies.
So, i want to implement a gamepad for my little world scroller game. I downloaded both the GamePad Template and the GamePad Tester scenarios. After opening the scenarios, I get a whole list of error messages mostly saying either certain packages do not exist (such as “package net.java.games.input does not exist”) or certain classes cannot be found (like “cannot find symbol - class Controller”). I can’t name specifics and there may also be other types of errors that I have not yet seen mainly due to the fact my computer is literally getting hundreds of error messages whenever I open up ANY of the greenfoot GamePad scenarios. Did I download anything wrong or are the scenarios just in serious need of updating? Any help is appreciated.

You can try this to display minutes and seconds: (I partially copied it from one of my scenario, so some of it is German. But maybe that's not a problem, because I saw you using the word "nichts" in your last post.) ;) << Code Omitted >>
I think the code supplied might be a bit advanced for FlorianZhu with usage of an array, the Font class and especially using an inner class.

Or, use: <Code Omitted>which is equivalent to: <Code Omitted>This is presuming that exactly one killCounter object is always in the world.

The SmoothMover class or my QActor class (see my Demo Collection) could be used to help in controlling the speed of the actor.

The following would be like the reverse method ("function"): <Code Omitted>Pretty simple -- probably not worth creating a seperate method for.
