![]() ![]() What is it very important is that they know the principles and basic structures. It is useless learning every line of code by heart when it is readily available online. Surely some keywords and syntax they will need help from the teacher, but in the end they would come up by the code, and if they get stuck you encourage them to search online. Then encourage the students to come up with a simple program themselves. This I believe is a good way to start out as they start understanding more how to think abstractly which is fundamental in programming. They would be in command of the situation and this motivates students a lot. For example move forward, turn left, until you hit the wall. Another way could be starting up with real life examples for example telling the students to command me as a teacher to do certain things in class. Then what I would do is explain certain programming principles in general which they have already come familiar with in Greenfoot, like sequences, iteration and so on. ![]() I think what I would do is first introduced to students to a programming language like Greenfoot or Scratch where they see it as a game, but would be gaining fundamental programming skills. Some screen shots of Greenfoot can be found here: As we can see, there are loads of possibilities as to how one can use Greenfoot. An example of this would be: two people walking towards an ice cream van to get ice cream or a kid bouncing a ball towards the edge of the screen and the ball bounces back to the kid. In the classroom, it can be used by for example telling the students to have the program act out a short short while the student is narrating what is happening. Since Greenfoot uses the actual Java code, the students are learning Java in fun way compared to the usual text based programs such as when creating a simple calculator program. When the students see that they have managed to make a moving character with a few simple lines of code, they would probably be encouraged to make their Greenfoot application even more interactive. This actor can have its controls mapped to the keyboard so that the student will be able to move his or her actor around. There are many pre-defined methods such as turnLeft() or setLocation() which allow the programmer to easily move an actor around. Greenfoot should be used to encourage the students to not give up programming if they find it difficult as it lets them immediately create the thing they were trying to do. If( Greenfoot.Greenfoot is an application which allows its users to use Java code to easily create simple graphics or visuals. While you are there, make sure you are minimally familiar with all the tutorials provided on. Go to for easy-to-follow instructions on downloading and installing Greenfoot. Then, we will layer on additional functionality, such as scoring, introduction and game-over screens, and the notion of levels.Īs mentioned in the preface, we'll assume you have downloaded Greenfoot and have it installed. We will first build the basic components of the Avoider game, including the initial scenario, the game environment, the enemies, and the hero. ![]() We will pause frequently to consider best practices and good programming practice. As with Michael James Williams' tutorial, we will start small and slowly layer on functionality. We will build the same game in Greenfoot, instead of Flash and ActionScript. The longer you avoid them, the higher your score. The goal for the player is to avoid these enemies. In that tutorial, you build a game that creates smiley-faced enemies that rain down from the top of the screen. This tutorial is heavily based on AS3 Avoider Game Tutorial by Michael James Williams ( ). This chapter provides the framework to create Greenfoot applications that we will continue to use, and refer to, in later chapters. Many of the chapters in this book are independent however, most are dependent on this chapter. In other words, follow the advice of Confucius, quoted in the first line of this chapter. Experiment with the code and try new things-you'll be glad you did. Be sure to look at the simple tutorials and documentation at when needed. Similarly, this book assumes a minimal understanding of Greenfoot. Java is a well-established programming language, and there are endless online resources you can consult. I love this place All of the employees are friendly, knowledgeable, and welcoming. If you are new to Java, or it's been a while since you've programmed in Java, be sure to take the time to look up things that may be confusing to you. Excellent customer service, and their rewards program is a HUGE bonus. As you proceed, think about the concepts presented and how you would use them in your own projects. Throughout this chapter, we'll learn basic programming concepts and gain familiarity with the Greenfoot development environment.
