thanks a lot

@SPower Ok thank you. I don't think this is very usefull but if its normal I'll try to use other ways.

This is actually gonna help considerably in the late stages, but I meant I have literal world cells. Each of these segments are representing a different "room" or "land". In the end product it will be much larger with several spaces filled with nothing at all. Hence my use of the text doc as I figured that would be more efficient. My mind tells me that each respective string could be added to a array to be loaded later after the text doc loads this system. I don't know how to do that and still follow the organization of my world however.

'Counter counter' in itself tells the compiler that you have a variable call 'counter' and it is to hold a 'Counter' object. You cannot assign an 'int' or any other type to a variable of 'Counter' type; it must be an instance of the 'Counter' class. You can, however have an 'int' variable within the 'Counter' class. An example of a simple Counter class follows:

I found this software not too long ago: aseprite.org It looks pretty good. You can save the animation as many different filetypes like gif or png. Png is cool because it'll keep the opacity and it saves a separate image for each frame so if you know how to switch out the images to get the animation going then there ya go. Otherwise I've been trying to find out how to even do animation in greenfoot. Oh, and the software is free.

Then you shouldn't ask it if it has nothing to do with PROGRAMMING (like your subject is) or greenfoot.

Thank you, it helped a lot!

Here is what was happening. 'getObjects(PowerSource.class)' returns a list of objects of type 'Object'. Objects of that type cannot use 'Actor' class methods or variables. A simple way without having to import the list class <Code Omitted> Hope this makes sense.

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.
