If your code above is in the Wombat class, then use this instead of Wombat.

thank you :-)

As is, your else part will execute regardless of the state of the D key (since else is linked only to the A key part). Move line 12 to the beginning of the method and then instead of else, just ask if it is still false at line 11.

The same can be said for the Good component field. That is, the line: <Code Omitted>would need to read <Code Omitted>for the field to obtain a value and for the getGood method to return that object (and not null).

I filed a ticket for this in our bug database, thanks.

You start with a World object and some Actor objects. What have you tried? (your question does not conform to site standards -- not specific enough and no code given).

I tried now different solutions and I think I solved my problem now. Thank you for helping.

You can use a "getter" and a "setter" method in the class where the array is located. Like the following (presuming the array holds int values): <Code Omitted>Then in Class_B. you could use something like: <Code Omitted>

Good question. The required HTML-Files come with the download. However, the program doesn't seem to find it. In the title it says "null" and you get an error when trying to open it in a browser telling you that the requested file can't be found. Unfortunately, I didn't find a way to make them appear by clicking on Actor/World. Seems to be a bug in 3.5.0. You can also find the Greenfoot API here: https://www.greenfoot.org/files/javadoc/

<Code Omitted>

It depends on the condition. Examples: <Code Omitted><Code Omitted><Code Omitted><Code Omitted>

You could define a new variable which counts how long you press a button by adding +1 every act-step the button is pressed. Like so: <Code Omitted>
