Feel free to close the “wombat” scenario if you’d like. 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.
GREENFOOT BUTTON INSTALL
There are several scenarios that came with the Greenfoot install and they are located in /scenarios. 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.Ī Greenfoot Scenario is just a project. 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. You can also consider a class like a 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.Ġ0000101010000001010101000110001010101010101010Ī function is a unit of execution. 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?). Quick intro on Programs, Functions, Classes, Subclasses, and ObjectsĬomputer programs are one way for humans to communicate with machines.
