java.langNullPointerException

Last reply by ttamasu, over 13 years ago:

I'm probably stating the obvious but let me get it straight: you have a instance of the class called _recorder and you initialized it like so : _ recoder = new Recorder(); // or something like this before you made the call: _recorder.keyPressed("S2"); right?

Or, if you want to be more explicit: <Code Omitted>to avoid 'Tree' from producing 'Treefrog'.

If you are calling a method that is not in the same class code as where you are calling from, then you must tell it (the compiler) where that method is located. In your case, the method was in the Board class (not just the World class). The methods inhereted from the world you can just say 'getWorld().methodName()'; but for methods you write in your Board class, you have to tell it '((Board) getWorld().methodName();', or it will not find it. The '(Board) getWorld()' part is what 'casts' the world returned to you Board class.

Wow, I kinda thought it was something

Writing a file

Last reply by K_O_P, over 13 years ago:

@ Busch Maybe you can store more ints, when u use Symbols instead of numbers if you take 100 different symbols, you can write the numers 0 to 99 in just one space! you just need a method that converts a number in this code and backwards.

but actors cant add objects to the world right?

That is not quite true. As long as the actor is in the world, you can use the 'getWorld()' method to access the 'removeObject' and 'addObject' methods. <Code Omitted>

List.toString() then String.toList()

By Razzo, with 3 replies.
Last reply by tkiesel, over 13 years ago:

I should mention that while the work to write something like this can be finicky and tough, once you have it, writing new levels for your game becomes so much easier, and for really complex levels, your world file can shrink from an enormous monstrosity to something far more manageable! :) Two high school students of mine (with some help on file IO from me) used this basic system to write a Galaga-type space shooter, and their level Strings even included timing data. Cool stuff.
