We do not discuss this scenario in the chapter, but it serves as a model demo for studying how a cartoon character could be controlled by gestures. Again, making use of the Microsoft Kinect.Ī very simple game, but this time with gesture input instead o keyboard control.Ī last demo scenario for the Microsoft Kinect. We extend the skeleton tracking to allow multiple users to paint on screen by waving their hands in the air. Using Kinect input to create a greenscreen effect (placing a user in front of a fixed background image).Ī demonstration of skeleton tracking with the Microsoft Kinect. Showing a camera image on screen, using the Microsoft Kinect. This scenario is fairly complete, and we use it to make some experiments and gain some understanding about the nature of simulations.Ī simulation of ant colonies searching for food, communicating via drops of pheromones left on the ground. This example is used to practice more work with color.Ī predator/prey simulation. In general, it serves to discuss dynamic drawing, to create more interesting visuals.Ī small scenario demonstrating a creature following a colored path on the ground. This scenario demonstrated a visual effect: smoke trailing a moving ball. This scenario is a competition: program the greeps so that they collect as many tomatoes in a limited time.Ī small scenario just to display a chart of RGB colors. This scenario could also be used much earlier for similar exercises.Īlien creatures land on earth to collect tomatoes. ![]() 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. ![]() It's just the application and the zip file.Introduction to Programming With Greenfoot - Translations Do you know how to change the shm on a Mac? I can't find an installation folder on here. I don't see anything weird with it but I'm not sure.
