Just a note: you should prefer "isEmpty()" to "size() != 0", because it is more descriptive, and it can be (much) more efficient - some types of list have to count their elements when you call size().

Thank you! I had tried your first example by using "getWorld()". However not using "getWorld()" was more succesful on how it worked when no zombie was in the world but would error when the actor was removed. But doing both made it work. Thank you davmac

I'm not quite sure, but it seems, that the problem solved itself... I haven't done anything and suddenly it works!

it would be easyer to help you if you could show us the part of the code which is important for this.

If in the construktor of the world (probably the first method in world: public world() { ...)) stands code like this: super(17, 9, 64) minX would be 0, maxX would be 16, minY would be 0 and maxY would be 8.

freesound is a good source for sounds.

make a static variable for the money, and variables for #bombs and #food. Then make a button in the store, with methods that removes money and adds objects. During game, check the variables for the objects if the method for using them is called.

54 is the distance from the left key to the left of the world. You don't have to change that.

Oh, sorry, I forgot to restart it. It works now. Sorry.... And thank you

OK, so I found the problem: saving a scenario is really saving a folder. I went to copy the file and found the file is a folder with lots of supporting information included. What actually gets opened by the editor is probably the source code. All the rest of the material in the folder is available for the exercises. I will save the scenario as an Chapter and exercise number.

To accomplish this, you will need two instance variables: one boolean and one int. The boolean will track whether the powerup is active or not; the int will act as a timer. The code will need to be in the hero's class.

You're welcome :)

Pull up a blender representation of a cube. If you look at it, it isn't to hard to figure out which part is doing which. After that, just figure out how to use a filereader to read it and then convert it into something useful for your program. The converting might be tricky, since you have to use string manipulators for that and such, but try it. I am actually working on something like that right now (sorry BuilderBoy,I only copy code if I can understand what I need in a minute, or else I start to feel guilty about it.)
