In addition to teaching programming, Greenfoot can also be used as a meta framework for micro worlds. Greenfoot solves this problem by creating a live object world framework in which students interact with new objects as they are developed. Students can also be discouraged with all the scaffolding that must be built before their creations come to life. However, don't let this discourage you from letting your little ones try out Scratch.īeing proficient enough with programming to be able to write Java source using Eclipse or any of the other popular IDEs is the ultimate goal, but new students who find Scratch easy often find a fully integrated development environment intimidating. When this happens, it should be taken as a sign that it's time to move on to a more powerful platform like Greenfoot. For this reason, it has its limitations (such as no dynamic object creation), which can lead to frustration once the platform is mastered. Scratch distills programming down to a series of drag and drop operations. It's a great environment that requires only basic reading and math skills anyone six and up would have a blast with it. One very popular platform for teaching the basics of programming logic is Scratch from the Lifelong Kindergarten group at the MIT Media Lab. Homeschooling parents, computer science instructors and tutors continually seek new and engaging ways to teach children computer skills.

Greenfoot: a live object world for studentsīy Nathan Tippy, OCI Senior Software Engineer Greenfoot, a live object world for students.If anyone could help me that would be great. So when the lobster that has be added to the world eats the crab, I want that crab to lose a life, but when I try to compile, I get an error on the CrabWorld class that it could not find the method mentioned. If(Greenfoot.getRandomNumber(100)= getWorld().getWidth()-10) * Randomly places worms at random periods * Prepare the world for the start of the program. * Constructor for objects of class CrabWorld. Private Counter score = new Counter('Score: ') * place random worms in the world over time. * Creates the crab Enviornment with a counter, crab and lobster. I need to access the Crab instance (created in the CrabWorld, if that matters) from from the Lobster Class.Ĭrabworld: import greenfoot.* // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)

I have tried calling ((CrabWorld) getWorld), but I don't need to access the CrabWorld. This method would change the lives of the crab. But the important part that I am having trouble with is calling a method from the lobster to the Crab instance created by the CrabWorld.

For your sake, I'll just post the well documented code for you to read. It contains 5 classes named Crab, Lobster, Worm, Counter, and CrabWorld. Every time you eat a worm, the score goes up by 10. There is a lobster that randomly roams around and if comes in contact with the crab, the crab dissapears. I'm makeing a game where you play the crab and move around to collect worms.

I have become familiar on how to call certain methods between classes, and also differences between static and non-static. I have just started programming some things with Greenfoot, learning java along the way.
