Determine what conditions will be true when the actors reach that location and only move when that condition returns false.

easy you will notice i put in a variable name waitTime and its = to 10. to increase the time between each shot, increase the variable. so instead of private final int waitTime = 10; do private final int waitTime = 20; if you implemented that variable like i did. then changing that one variable will change the speed for all direction bullets.

all would be preferable thanks.

What about: <Code Omitted>

Nope not it. And now I notice Almost everything in the entire program might just suddenly dissapear. The bar to get to preferences was gone until I clicked on it. Then it turned visible. It's not that my text turns white actually, I think (parts of) it's just not displayed, and then it is, and then it isn't. As soon as I do anything (click, type, ...) some things go missing and some come back.

I've seen a similar error before (not in Greenfoot) if I remember rightly, when the same port was being used elsewhere. With that in mind, only other thing I can think of would be to shut every other program down (including any system utilities running in the background) and then try again. If that does solve the problem try re-introducing the programs one by one to see which one is the culprit.

It would probably be better to use 'Actor.class' (or the actual name of the class belonging to the object you want removed) instead of 'Object.class' in the above. However, if you are going to just re-introduce another object of the same type as the one removed, do not remove or add, but just re-locate the actor found: <Code Omitted>

Ok! I can't say it's crystal clear yet, but I'm getting there. :-) In the example in the book on pages 89 onwards, the world object is not defined (or referred to by a variable) anywhere in the body class, which means it is necessary to use a method that returns the variable (in a List in this case) referring to the object (?). Thanks!

thanks a lot it works now :)

i fixed it :D Thanks so much :D

it solved :D i take the luigi dead off and the getObjects(Bomber1.class).isEmpty(); in the if function

See tutorial #6 (under Documentation).

If you want, you can re-write the code.... I can then see what you wrote for future things. How do you think my programming is for a High-schooler that started Greenfoot in January?
