The greenfoot system also provides a full IDE, including integrated editing, compilation, creation of new classes, object inspection and a source level debugger. Scenarios are completely decoupled from the visualisation and interaction framework, so that greenfoot can be used for a wide variety of graphical applications. In addition to this, greenfoot allows direct interactive method calls on simulation objects, similar to the interaction facilities in the BlueJ environment. One aspect of greenfoot is that it allows visualisation of appearance and location of simulation objects in a two- dimensional grid, similar to micro world systems, such as Karel J. It provides a framework and environment to create interactive, simulation-like applications in a two-dimensional plane. The greenfoot system is an interactive object world. We describe the motivation and environment mechanism for supporting this below. The goal of supporting an interaction mechanism for running applications – for the purpose of developing game-like applications – has recently been added and was not included in earlier discussions of design goals. Some of these design goals have been discussed in more detail in.

to allow for easy development of interactive scenarios, for example interactive games, by students to support migration to other environments.

to provide a clean illustration of object-oriented concepts.

to support highly flexible scenarios, while freeing scenario writers from dealing with GUI programming.

to allow active interaction and experimentation with object instances and to explore behaviour interactively.

to provide visual feedback of object state and behaviour.

in detail, we give a brief summary of the main design goals, which will help to put into perspective those decisions we discuss later in more detail. include this sort of method in Level1: public void changeLevel()įor (Clover c : getObjects(Clover. You can do this by going through all the actors of the type you are interested in, and removing them from the existing world and adding them to the new world. I don't want to make this answer too long, but hopefully that gives the general idea: have a shared parent world class which both level classes inherit from (using extends), and then both level classes can call methods from the shared parent.Įdit: sorry, I think I just understood more clearly that you also want to transfer the actors between the worlds when switching level. Then you have two level classes, each of which extends DoggieWorld (not just plain World), allowing you to call the spawnClovers method from each: class Level1 extends DoggieWorld If (Greenfoot.getRandomNumber(1000) < speed)ĪddObject(new Clover(), Greenfoot.getRandomNumber(getWidth()), 0) So you might have: class DoggieWorld extends World they both spawn clovers) then you probably want a shared parent class.

If you want to share code between your levels (e.g. They will both appear directly beneath World in the class diagram. So you might have: class Level1 extends World In Greenfoot, levels are usually implemented by having different worlds.

Declare Greenfoot images for standing still facing left and right Declare arrays of Greenfoot images for animation import greenfoot.* // (World, Actor, GreenfootImage, Greenfoot and MouseInfo) How am I supposed to do that? In other words, I can't seem to transfer the same things from GameWorld to Level1, which includes the clovers, candies, and score board, when a certain condition is met (i.e., a specific number of points is reached)? FYI: I've used a separate actor for the score board (hope this helps.).

However, the thing is that I want to create multiple levels, and that I kind of want what I have for the first world (named GameWorld) to appear in level 1, which is in a different world. What this game basically does is that the actor, Doggie, will try his best to catch the clovers and special treats that seems to be falling from the trees by running back and forth across the screen (through the user's left and right arrow keyboard input, of course). For a Greenfoot final class project, I decided to make a game called "Doggie the Super Catcher".
