Either way, you perform one check that verifies that a MouseiInfo object will not be null. Also, in this case of PascalFisher, no actor repositioning is required unless the mouse is moved.

Thanks, I think I know what I can use a while loop for now.

I see what you tried - „if either one of the left and right arrow key is down then execute this“. However, what you say with this in the inner part of the statement is „left or right“, and that would be an or between two strings. You can only use the or operator between two boolean values though. So the proper statement would be: „If either the left key is down or the right key is down then execute this“. Try to express that in java now.

Thank you so much! I just came to that conclusion myself and your confirmation really helps!

I uploaded a demo for you. It is here.

I am still experiencing the same issue

Thank you for your help, I really appreciate it.

Edit: I found my Issue. Instead using "this.removeTouching(Benzinkanister.class); " I used "getWorld().removeObject(Rakete.class);

It doesn't seem to change, sadly.

Not enough info. Show all codes related to backgroundMusic and indicate exactly where the codes are located.

No collision checking methods can be performed on an actor outside of the class(es) of that actor.

In Actor subclass, use: <Code Omitted>for <Code Omitted>in world.

Move the last line in the act method up two lines (so you do not look for zombies after being removed from the world).
