Engaging examples in the form of games, simulations, and music make programming fun and stimulating for all students.Projects are introduced first with interactive examples and later explained theoretically, allowing students to practice skills they are learning before understanding dry material.Wave is the simulation of the propagation of a wave on a string.Platform jumper is a demonstration of this popular simulation.Breakout is the beginning of the classic breakout game with an interesting visual effect.Explosion demonstrates a sophisticated explosion effect.Circles makes patterns in different colours on the screen with moving circles.Boids is a demo showing flocking behaviour through the motion of birds.Lifts is a start of lifts simulation that can be continued into its own project.NEW! Chapter 10 has a variety of new examples that intend to inspire further projects, such as:.NEW! Chapter 6: Newton’s Lab is a simulation of the motion of stars and planets in space that teaches the concept of gravity.NEW! Chapter 1: Leaves and Wombats introduces some important object-oriented concepts and Greenfoot interactions early on in the text.NEW! Examples have been added to the text that allow students to practice programming in an enjoyable, engaging fashion, such as:.UPDATED! A highly interactive text teaches through hands-on examples All Greenfoot examples teach basic principles of standard Java, a fundamental language in computer programming.
#GREENFOOT GREEPS SOFTWARE#
Students have the chance to build simple games or complex, highly-structured programs in this environment, making the software accessible to a wide range of students.Greenfoot uses simulations and games to teach programming skills, making the topic interesting, hands-on, and enjoyable for students.
#GREENFOOT GREEPS HOW TO#
I know I can use turnTowards() however I don't know how to determine the closest enemy and how to get their location (getX and getY aren't static so that doesn’t work)Ĭan anybody explain to me how I can do what I want to do here? Also please explain it so I can understand it better and implement it better, since I don’t want to just copy some code from the internet but rather get an example and transfer it into my own code.Introduction to Programming with Greenfoot: Object-Oriented Programming in Java with Games and Simulations includes the following features to stimulate learning:īasic Java programming principles are explored in the context of Greenfoot My problem here is that I don't know how to make the homing bullets turn towards the enemy that is the closest to the player. The enemies will be constantly moving so the homing bullet would need to change its rotation accordingly while moving towards it and dealing damage to it on contact. It should decide which enemy to turn towards by how close the enemies are to the player and then pick the enemy closest to the player. The homing bullets should be spawned by the player and then turn towards an enemy of any type. To better explain my problem, I will give the object that should rotate the name: “homing bullet”, the class that the other class should be closest to: “player”, and the classes it should turn towards: “enemy type 1”, “enemy type 2”, etc. Right now, we have the task to make our own game and I am struggling with something. So, I am currently learning Java with Greenfoot in school (11th grade), and we are pretty basic right now (we only know if and while statements, variables, how to write methods and what an actor and attributes are).
