Adding the boolean field 'a' and method 'isMoving' was not required, or even needed. In fact, as far as I can tell, you are not even calling the 'isAtWorldEdge' method; so, it is not a factor. Since you do not need to use any of the methods you supplied in the Character class, I have the Guard1 class extending the Actor class below; however, you could still put the act and move methods below in a Character or Guard class so more than one class can have the behavior of moving back and forth and have those classes extend it. This is the basic code for an actor to move back and forth from

A much simpler solution is to make the GreenfootSound field in the Cover class 'static'. <Code Omitted>Then the method to stop the sound in the Cover class would be: <Code Omitted>With this, you do not have to pass anything from level to level. Just start the loop in the Cover class and use the following in the Level5 constructor to stop the loop: <Code Omitted>

Thank you all, I think I will start them with Greenfoot, and run them through the exercises in the book (have to buy the book first). This should get them started, and potentially mostly on their own while off for the summer and when I am at work.

thanks

There would be a lot more involved if you actually wanted to change the font style as well (importing the Font class and applying the font style to an image before drawing a string on it).

If you declare both the 'tpic' and 'g' images in the tower class and create the images in the constructors of the subclasses, then you should be able to use the code I provided in the tower class using 'setImage(tpic);' and 'setimage(g);' at lines 11 and 6 in my code above. When upgrading the tower the 'g' image will need to be updated, also.

Indicates where the statement terminates. Probably mostly to aid the compiler. In Java you can write an entire program on one line.

Forgive me if I am wrong, but it appears that the 'atTurningPoint' method will always return true. The x-coordinate of the enemie will always be either less than or equal to leftTurn (450) or greater than or equal to rightTurn (also 450). This means that the speed will always be changing directions and your actor will jiggle in place. Your conditions for turning in your 'atTurningPoint' method needs some work.

had the right idea, was sticking it in the wrong part lol. thanks for the help.

Your class is never closed. Try adding '}' at the end of your class. That may help.

In order to manually place them on the map, they must have a constructor method in the class. For the class given above, add this constructor: <Code Omitted>

Could you explain it a bit better? If I understand you correctly, you want to spawn the player again when he dies... If that's the case, just set the world to a new version of that or something. It will look like the world is reset, but it didn't really reset. Or you could have a reset method that adds/deletes objects back into their original places (such as the MainPlayer at the beginning of the level)

Thank you so much!
