Just to expound a bit more, changing the statement to avoid the 'new boolean' doesn't work for me; this workaround might be Java version dependent. A workaround that should work for all Java versions is to declare the field either public or private, eg: <Code Omitted>

This is the classic 'two methods that remove the actor' problem. If you have two methods that each can remove the actor (the bullet,, in your case) from the world (methods are 'disappear' and 'destroy'), then if one remove the object, the other one will throw either the IllegalStateException or a NullPointerException. This can be solved by testing if the actor is still in the world after the first method is called (checking the return of 'getWorld' for 'null').

I will just share here when I have time. Thanks for helping!

LOL! Never mind, I figured it out. I forgot to use the "setRotation" command. :-P

At least two things can cause missing the target destination (1) the limitation of rotation to int values and (2) the limitation of pixels on your screen. How fast your actor moves can limit direction because of (2). For example, at a speed of 1, you actor can only go at a multiple of 45 degrees to 8 possible locations at a time -- the pixels to either side, above or below and to the four nearest pixels along the diagonals. At a speed of 2, you cannot add more than 8 new possible directions to go in; so, the number of possible directions your actor can go is still quite limited. You can

Line 8 should be: <Code Omitted>with the round brackets after the class name.

Fantastic work!

If the game will be beatable at level 9 then you will have to incorporate another way to exit the levels. Maybe just asking if no boids are in the world is enough. <Code Omitted>You could at that point then just increase the number of boids per level.

its fun to see other people asking stuff about the same school project ;)

Thanks it worked!

Thanks a million man, that fixes it.

'getWorld' is a method of the World class, created long before you wrote your subclass of it. It can only return a World object (which can be from any subclass of World). It cannot return your world specifically as a 'RoboterWelt' world object; so, you must inform the compiler that it is indeed one so it knows to look in that class for the method.

I made a method for each of them like you suggested "bCost" wCost" and "bValue" each as integers, bCost and bValue returned 1, and wCost returned 0. I'll cut out a piece of the code for an example. <Code Omitted> ^ Wall class

Oh, but yes, I do want to do raycast. This project is primarily for the learning experience, and just in general, trying to master the art of 3d rendering. I will probably copy my code and try doing it another way.
