I understand this, but Greenfoot is a very nice program for both learning and making good looking games. I have seen many. I also do not want to use any other engine, as I am currently learning Java.

Thank you danpost, this helps me out a lot. :)

Thank you helpers, you input aided me to see what I really wanted to achieve and have now solved my problem.

Ah, I see.

Okay thanks, I'll keep that in mind.

Greenfoot will open two types of files. When it opens a GFAR file, which is basically a zip folder, it creates a file folder with the unzipped files in it. This file folder is the other type of file greenfoot will open. So, if you do not yet have a file folder that is a lobster and crab game scenario folder, then open the GFAR file with greenfoot. If you just downloaded greenfoot, you may not be able to work or open the scenarios until you move or copy the scenarios folder to some place like in the 'My Documents' folder (you need write permission in the folder to open the scenarios from)

Danke, werde es ausprobieren sobald ich Zeit habe.

Ha! Thanks, DanPost, I just figured out that it's HTML. Don't know why that didn't occur to me.

Then just move it into the Marker class where it will be accessible to it and all its subclasses. Make the array a 'static' one so the objects created from its subclasses all share the same array and are not given individual arrays to work with: <Code Omitted>If you only want the array accessible to the Marker class and its subclasses (that is, you do not want any other classes to have access), then use: <Code Omitted>

Nope, that didn't work. Ok... It turns out I spelt addedToWorld with a capital A...

Your 'moveAround' method has the wrong type of movement for an actor that is supposed to be able to jump. You should not be using 'turn' and 'move'. The vertical movement is determined by surfaces and jumping; the horizontal movement should be adjustments to the position of the actor along the horizontal (changes in what 'getX()' returns) using the 'setLocation' method with detection of the 'A' and 'D' keys (obstructions should also be detected here). The 'W' key can be used for the trigger for jumping and the '1' and the 'S' key detection blocks can be removed.

@Super_Hippo, sorry if I made it seem your response was incorrect. If I had looked a little closer as to what you were pointing out, I would not have responded at all. In fact, if you notice, I qualified the apparent discounting with exactly what the problem was: Again, I apologize.

If there are edges of your images that are totally transparent (edging that can be removed without removing any of the actual image, you could load them into my Image Transparency Adder/Trimmer scenario and re-save them (all excess transparent edges are removed automatically -- just load and save). You can download the scenario, open in greenfoot and save it as an application for future use.
