(In this scenario, there is only one actor, which is represented by an image of a spider. The blue rectangle on the left in Figure 1 is the stage upon which the actors perform. This is an animation scenario involving a stage and an actor. Visual manifestation of the Greenfoot IDE. The visual manifestation of the Greenfoot IDE, version 1,4,1 is shown in Figure 1.įigure 1. I’m going to begin by giving you a look at a very simple Greenfoot scenario. You will find a consolidated index at A simple Greenfoot scenario I recommend that you also study the other lessons in my extensive collection of online programming tutorials.

Class definition code for the class named MyActor. Class definition code for the class named MyWorld. Method inheritance information for a MyActor object. Result of selecting the new MyActor() option. Dialog for specifying name and image for new class. I recommend that you open another copy of this document in a separate browser window and use the following links to easily find and view the figures and listings while you are reading about them. For purposes of this tutorial, the two terms are interchangeable.

Publish the scenario on the Greenfoot web site for review and comment by others.Īs a matter of clarification, most of the Greenfoot documentation uses the word scenario to describe what might be referred to as a project in other programming environments and IDEs.

Export the scenario as an application in an executable JAR file.

Export the scenario as a Java applet in a JAR file with an accompanying HTML file.

Execute the scenario (project) inside the IDE, either in single-step mode or run mode.

Included in that power is the ability to do any or all of the following:

Greenfoot is powerful because it allows for the use of the same Java code that an advanced Java programmer would use in a major Java project. Greenfoot is fun and engaging because Greenfoot makes it relatively easy for novice programmers to create 2D games, animations, and simulations. (Note that your browser must support Java 1.5 or later for this applet to run properly.)

Flip the switch on the upper left to switch between manual operation and an oscillator. Move the Amplitude, Frequency, and Damping sliders to change the physics of the simulation. Click the Run button at the bottom and move the blue bead to activate the wave motion.

Greenfoot provides a painless, fun, and engaging entry point for novice programmers but also supports the full power of the Java programming language for more advanced programmers.

Greenfoot is also available free of charge. Greenfoot is a combination of a Java IDE that provides a class browser, compilation, interactive execution, single-step execution, a code editor, etc., on one hand and a framework for creating two-dimensional animations, games, and simulations on the other hand (see Greenfoot Home in Resources).

Import greenfoot.* // (World, Actor, GreenfootImage, and Greenfoot) Here is the code example from the piano class: I am confused in general how the program knows that the keys are set from left to right in the first place. The remaining keys should be next to each other, with no space between them." Rewrite it (in this document only-not in your working Greenfoot program) to create the keys from right to left, instead of left to right, and force the rightmost key to be flush against the right side of the screen. With this information in mind, copy the new loop code you entered to correctly place the keys in the space below. Recall that the piano is 800 pixels wide. "According to the text, Greenfoot refers to objects by the midpoint of their lengths and widths. I am working on exercise 5.18 (not the same as the book example) and it says: I am working on my assignment for school and this question has thrown me for a loop, no pun intended, this chapter is about loops and arrays.
