- move - if it touches a wall --- move back and turn

If you can access it, you should be able to change them the same way. The proper way is to use getter and setter methods. <Code Omitted>

It seems like 'counter' is null and not the counter in your world.

danpost you are a legend, I love you mah man. Now I will get A+++ on my ict because of you. I want to meet in real life and shake your hand my good sir. Also thank you for fixing my problem I love you to Nosson if it was not for you replying dan would not have come here and suggested how to fix my problem so I can have my LMB to shoot, i will stop have a fantastic you two <3

The following is the exact message that I receive: Application Error X ClassNotFoundException greenfoot.export.GreenfootScenarioViewer.class <Details> <Ignore> <Reload> I am also NOW on the latest version of Java (and Greenfoot). When I click on the button that says "Details" a new window pops up which says: Java Plug-in 11.121.2.13 x86 Using JRE version 1.8.0_121-b13 Java HotSpot(

So basically you should read this. You don't need to use a GreenfootImage. You can just do: <Code Omitted>

If you want all your subworlds to share a single field whose value is retained from world to world, then make it a 'static' field. For example: <Code Omitted>Just make sure to explicity reset the value of these fields in your initial world object. Refer to my Super Level Support Class scenario as an example of what I mean.

Well I solved that problem, I tried to add Trees in an actor class not in a world class. Thanks for the help.

I mean that you use 'counter' but nowhere in the code shown above you declare what 'counter' is. So you could write some random letters instead and will get the same result.

I guess another way we could fix this is if the w key is released or not pressed it sets jimmy back to his 1st frame or something and that will also fix his legs in the air problem because when it go's through the animation frames it will just be stuck on a certain frame and i would rather go back to the beginning frame

For your code you would probably have to do: <Code Omitted>

The object is not "deleted", it is only removed from the world. You can do anything with it after it was removed which does not require the object to be in a world.

You could reduce the transparencies of the images of the inside walls (just by one) so your character can determine which he can go through and which he cannot.

Each row of invader must be controlled from one central location -- in other words, they should not each control their own movement. On top of that, all rows of invaders must be controlled from one central location because if any row has an invader at the edge and needs the row to drop and move back across the other way, then all the rows need to drop and move back (in succession). My Space Invaders Movement Demo scenario shows one way to accomplish this.
