I am saying that in a side-scroller with a background image like this: <Image Omitted> there is really no change in the image. So, why scroll it at all. You still need to scroll the actors; but, the background will then only appear to scroll.

The main actor should have a reference to its gun and control its location. That is, set location to (getX(), getY()), set rotation to 'getRotation()', move some distance out from center of main actor, turn(90), move some distance sideways, and turn(-90). Doing this at the end of every act cycle (after the main character has moved and turned) will keep the gun in place. The gun object should create the bullet objects and add them into the world, initializing their rotations and placement in a similar fashion (except not continuously).

The steps involved are explained and illustrated in my Value Display Tutorial. Maybe it can help you out.

After the 'int count ...' line (line 11 above), try adding the following line: <Code Omitted>This will prevent any zero-sized arrays from being created. Maybe you should investigate further as to why a zero was being returned by the 'getRowCount' method from DBConn -- or maybe not (I am not sure if this is something that is okay with you or not).

You can only use 'getKey' once per act cycle. You are using it four times here, at lines 23, 28, 33 and 38. Any key return by line 23 will not be returned again on the subsequent lines. If no more keys are waiting in the keyboard buffer, 'null' will be returned. Hence, the subsequent codes for firing never execute. Get the key once, before any checks and hold it in a String variable; then, compare the contents of the variable for the matching values: <Code Omitted>

thnx

It can be done; but, only locally. It cannot run that way on the greenfoot site or in a webpage.

never thought about it like dat

Replace line 18 through 23 of your Letters class, as given above, with it.

Will you be turning your actor (changing its rotation) when an edge of the world is arrived at? or, will it face the same direction and just move in the opposite direction? and, what have you tried, code-wise?

@danpost, I added code to the act method, placed the appropriate code in the appropriate methods and calmed down with my use of the brackets. Finally, after 3 days of getting no where my world is constructed! Thank you for all your help, I really appreciate it!

That works perfectly with the value set to 10 instead of 2, thank you very much for the reply and help!

Solved it.... There were two occurrences of the counter being defined! The first (which I had in the MyWorld) is shown at the top of my original post. I added this myself. The second occurrence I think has appeared when I saved the world. It was in the prepare method... <Code Omitted> The moment I removed it my code worked as intended. Thanks for your help guys, I know this is a stupid and basic issue, but I am just learning this from scratch.
