Hi! I'm pretty new to Greenfoot and Java,, at the moment I'm making a picross game. What would be the best way for me to check the solution to the puzzles against what the user enters? I was thinkin boolean arrays?
Is your program going to be checking that each entry is correct or not, or just checking the end result of the solve? The end result check should be simple enough -- in that all the clues must be satisfied (just check that). If checking along the way, then the solution should be stored in memory to see that each entry in correct (checking entry with corr

<< Code Omitted >> I cannot get this section to work. It says that variable "annahme" is not initialised and that is because it is not. It is supposed to be specified by the player once the previous check "if(gesteinVorhanden())" has been finished. Only then should "public void sammeln(boolean annahme)" be executed and a true or false should be given. : ( And "boolean annahme; sammeln(annahme); are correctly preparing that part, no? : (

You are probably letting the entity pass the barrier to begin with -- which should not be allowed to happen. When a collision is encountered, move the actor back to the original (x, y), which should be inside the barriers.

You need to describe exactly what you want. Showing more code might help. In fact, your
MyWorld
code would have information in it that would remove some doubt as to what you want. My first concern is how the world is created.

For some Reason instead of the Feuerball(Fireball) being removed, when hitting something a window opens itself with error codes because the code couldnt be carried out eventhough the return should stop the code from continuing. << Code Omitted >>
A

instance will only act when in the world. So,, it seems pointless for the first action taken to be asking if any of those instances are in the world (of course, the one acting is in the world). It would be much better to have objects it may hit to detect this object instead of the other way around. Tha

I guess this code is in an Actor subclass. To add an object to the world, you need to call the addObject method on the world the actor is in. <Code Omitted>

Microphone Permissions on Macbook

Last reply by nccb, about 1 month ago:
Just to let you know we've now found a solution. I've just swapped out the installers for the new 3.9.0 release on the download page with a version that should correctly request microphone permissions on Mac when you use the Sound Recorder.
