Maybe you need to use a method like this: <Code Omitted>

I know, I've been experimenting a little bit with my dad and found out that you do have to edit SmoothMover.(The method above was deleted)

No -- you do not have to edit SmoothMover. However, if you do, it should only be with the generic moving stuff. The shielding capability is specific to the player and anything related to it should be in the Player classs (that would be line 12 though 14, lines 33 through 52 and lines 138 through 142).

Hey. Is there a way for me to export just the documentation from greenfoot? as a pdf or another format? again, just the api, not the source code.

The documentation is in HTML format and is found in the 'doc' folder of your project. Viewing the class in Documentation format will create the HTML documentation file for that class. Some additional class documentations will be included within the folder.

Greenfoot freezes and does not say if the test passes or fail. I have to force quit to get anything to work after that. Thanks for looking over it. I'll continue working on the other programs and see if I can figure it out.

Maybe we should look at the code where you are creating a SedimentTest object.

Problems with an ArrayList

Last reply by danpost, over 9 years ago:

You should probably build your array from within the populate method, as those references are lost as soon as the method is done executing. If you are not going to do anything with the shuffled array list immediately, then you need to move the first line of your first code post to outside the method.

For 1a, write a method that will take the two int parameters for the actual and guessed values. Have it place the appropriate text at the center of the screen.

the plugin (and/or browser) had a corrupted copy of the Greenfoot core jar file in the cache, and so on after clearing the cache it re-downloads it - but that's really mostly guesswork on my part.

That answers my question enough.

Java Platform Binary has stopped working.

Is it related to the problem in this discussion perhaps? Greenfoot (since 3.0.0) uses JavaFX; Minecraft and the Game of Life program probably don't.

How to method it?

By HemantoPaul, with no replies.

Design and write a program which asks the user to enter his or her birth year, month and day using three different dialogue boxes. Your program should validate the user input as given below. You may write separate methods for each validation. If the user enters an invalid year it should display an error message “Invalid year!”. Otherwise, the program should ask the user to enter the birth month. If the user enters an invalid moth, it should display an error message: “Invalid month!”. Otherwise it should ask user to enter the day value. If the user enters an invalid day, it should display “invalid day!” Otherwise your program should calculate the age of the person to the date 2016-12-31 and display it on the console window

CursorImage

I tried that already. If I do that then the color of the mouse won't change since the changeMouseImage method is only being called once. Anyway I don't see how that's supposed help fix my initial problem(s). It didn't help, it's not helping, and it won't help.
