This is my idea for a Button class and I wanted to know if it is a good idea. I saw some ideas how to create Buttons, but nobody never really came up with a solution like this (as far as I know). However, I also wanted to know if there are improvements that could be made and if there is a way that the Button class doesn't need to inherit from the Actor class. Please reply. This is the code from the Button class: << Code Omitted >>
As far as inheriting Actor, you will need an Actor object to display the button in greenfoot unless you modify the background image o

When I said:
Right click on the boy and select 'Inspect'. Do the values appear to be okay, or is something off?
you responded with
No it seems to be fine.
Did you not see a bunch of null values (for the images)? Would that not seem off?

<Code Omitted>Hey 343qwm29, I hope this line of code will help you... A little hint: When you don't know how to do something, but you have an idea what your code has to do, go to your Greenfoot Scenario and click on "Help" and then on "Greenfoot Class Documentation" where you can find almost every method that Greenfoot has, and how to use it.

When you move a value in your arraylist, you destroy what was previously in the position you set. Change line 88 in HighScores class to: <Code Omitted>

I am trying that an object removes an object which is touchung another Object???

By Kili, with 1 reply.
Replied to by danpost, over 7 years ago:
A method with protected access can only be executed on 'this', which is implicitly understood if no object is explicitly given to execute the method on. That being said, to use isTouching on a ball object, it must be coded in the ball class. You can add a public method that returns a boolean value depending on the touching state in the ball class and call it from the other class.

It may just be a keyboard thing, Try a different key combination (maybe use 'x' instead of 'e').

I'm creating a program that contains multiple instances of an object. These instances spawn in a while loop and I want to say if ANY one of those instances is touching object x then do delete all further instances which I plan to do by using the break method in the loop. The problem I'm finding is that there is no direct way to say if ANY of the instances are touching object x. I was wondering how you guys would work around this problem.
Let me get this straight. You want to stop creating these object once any placed into the world ends up touching this object x.

Help with collision system

By TheSlorrow44, with 12 replies.
Last reply by nccb, over 7 years ago:
As I understand it, clone() copies all object fields exactly. But Actor keeps an internal identifier number, so clone() copies that identifier. Using clone() is almost certain to mess Greenfoot up, as it assumes each actor has a unique identifier. Instead, write a copy-constructor that copies the state you want.
