<< 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? : (
As a primitive variable type -- boolean, it requires initialization within a method or constructor. As an instance field, it w

object/entity passes through barrier

By soap, with 1 reply.
Replied to by danpost, 5 months ago:
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.

characters. << Code Omitted >>
Change from this: <Code Omitted>to this: <Code Omitted>The for loop works pretty much like the while loop -- in that it also must complete its execution (complete looping) in one act step. Removing the loop (without removing what is inside it) will have only one P

I used the SmoothMover because I could not get my character to move slower any other way, and that's the only thing that worked for me
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.

Remove isnt working

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 Feuerball 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>

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.

Simple fix: << Code Omitted >>
Sorry ... not quite so simple. The timer for respawning cannot be in the class of the instance for the actor removed from the world. It's act method will not be called to count the timer down. Since you will only ever have one instance of that actor at any one time, you can have the world run a respawn timer: (in CrabWorld)
