GameBall is its not on the board? So lets put it on the board! Butīefore doing that, lets me take a minute to explain how the Board Understand the Cell Layout of the Board What good is a This is all we will do with GameBall class for now. You should see the GameBall class under the Actor class as Create GameBall Class Right click on Actor button and selectĪs shown in the image: enter GameBall as the class name, select Of main project window to recompile the program. Recompile the program Click Compile all button at the bottom Once theĬhanges are saved, the changed status at the bottom would becomeĤ. Now hit Ctr+S or Class->Save to save the changes. The Board() function now should look like this: First,Ĭhange super(20,20,10) to super(3,3,60), because we want to createĪ world with 3x3 cells with a cell size of 60圆0 pixels (cell.jpg We need to make two changes to the Board() function. It is automatically called when a Greenfoot program startsĪnd is what we will modify to create the background. The function Board() is the default constructor of the BoardĬlass. To edit it in Greenfoots classĮditor, double click the Board button and a window will pop up. If your Greenfoot is installed underĬ:/Greenfoot, then Board.java should be inĬ:/Greenfoot/scenarios/TicTacToe. The Board class is defined in Board.java which is located in Right click on the World button and click NewĮnter Board as the class name and then select the cell image To create the TicTacToe board, we need to create a subclass of In C:/Greenfoot, then the sample scenarios will in underĬ:/Greenfoot/scenarios.

Select “Scenario”=>”New”, and then enter” TicTacToe” for the project name. For example, if your Greenfoot software is installed in C:/Greenfoot, then the sample scenarios will in under C:/Greenfoot/scenarios. There are several scenarios that came with the Greenfoot install and they are located in /scenarios. Create a new scenario A Greenfoot Scenario is just a project. For example, if a class called Hybrid Car is a subclass of the class Car, then Hybrid Car will not only have the features of Car but also its own battery-related feature. Using the Lego theme, a subclass of a class Car has a “mold” similar to that of the Car class, but its “mold” is enhanced to include battery-related features. All objects of the Car type will have features like move, stop, etc. An object of the Car class can be said to be of the Car type. If a class is named Car, then all objects of the Car class will have whatever features (aka functions) Car class has. A class is like a Lego mold and an object is like a Lego block. To compile a program is to convert the human-readable codes to machine-readable codes, which are binary codes.
Usually they are written in human- readable format such as Java, C++, python, and Ruby, but sometimes they are written in more cryptic languages such as assembly language (bytes and registries, anyone?).
