As far as the given method: First, the image belongs to an instance of the class, so it cannot be a static method. Secondly, if the method returns an image, then why would you say it returns an int value (int should be GreenfoottImage). But, the method is already a part of the Actor class; you do not need to create, or re-create, it. In general: If the images are to be given to Food objects, then the fields should be located in the Food class and the Food class constructor should set one of the images to the created instances. The images can be put in an array to give each an index val

Thank You!

Thanks, works perfect

It must be on the classpath though it doesn't matter how. However, the usual environment variable for specifying a classpath is CLASSPATH, and I'm not sure if its value is used if a classpath is also specified on the command line (which the BlueJ script does) and furthermore the tools.jar file is not normally listed in the CLASSPATH environment variable. You could of course modify the bluej launch script so that it included a value from an envi

The rotation of a ball has nothing to do with the direction the ball travels. So turning upon collision or setting its initial rotation should not influence the movement of the ball. Your collision method has yet to be executed as it still needs to be called from somewhere. That being said, it is no wonder that you are having trouble with the bouncing as the value of 'isFall' is never changed (nowhere is it being set back to true and, since the collision method is not currently executing, it is never set to false). All your actor will do is fall.

There are only hardware limitations as to what is (should be) possible. Create the menu World subclass and add the button Actor objects that the clicks are detected on (to start).

Okay, I will do that. Thank you so much!

I would think it's possible, since it's possible with java and that's what Greenfoot is, the question is How? Maybe this will help: Custom Networking

Okay. First, let me correct a typo in what is now your line 25 above, which should be: <Code Omitted>Now, your world constructor should begin like this: <Code Omitted>You may or may not have some parameters between the parenthesis. Curiously, I am not sure why you named the class that creates objects that represent lives 'HealthBar'.

See here. Instead of changing to Level2 change to GameOver, or instead of adding objects for new level, add in game over image/actor.

See here.

That depends on what your levels are (different world, just remove objects and place new ones, etc.). If your score to switch levels is 100 and you have an int field named "score" holding the current score, then you can use those in an if statement to change the level.

Alright. i gonna try to programm this tommorow.

Well my code is pretty short, and there is no other P, but it doesn't matter anymore, it works Thanks!
