This time, we investigate more fully how to implement it and add some more game elements.Īs the name suggests: a scenario with the sole purpose of reinforcing the use of loops. We come back to the asteroids example from Chapter 2. We also make a variant of this that combines gravity with making music, ending up with musical output triggered by objects under gravitational movement. Newton’s Lab is a simulation of the motion of stars and planets in space. It is not a game, or any completed project in any sense, but it gives a good first look at collision detection and lists. This scenario shows leaves floating in the air, occasionally blown around. You steer a white blood cell through an artery to catch and neutralize bacteria.Īn on-screen piano that you can really play.Ī small scenario serving as a platform to practice writing some loops. We develop it from a very primitive, rudimentary start to a full, playable game. This does not do much to start with, and we use it to do some exercises with if-statements at the end of the chapter.Ī typical side-scrolling game. Make the cat perform, while you practice your Java.Īnother small exercise scenario. This is a small scenario serving as a basis for exercises with methods calls and simple statements. Starting from almost nothing, we develop a simple game slowly, adding many things such as movement, keyboard control, sound, and many other elements of typical games. At this stage, we only use the scenario to make some small changes and illustrate how to edit source code to change program behavior. You fly a spaceship through space and try to avoid being hit by asteroids. This is a simple version of a classic arcade game. The scenario has no specific purpose other than illustrating some important object-oriented concepts and Greenfoot interactions. This is a simple example showing wombats moving around on screen, occasionally eating leaves. Introduction to Programming With Greenfoot - Translations
