ScratchFoot has been developed over the course of 3 summers by Prof. We would like to have a few teachers/students/Scratchers volunteer to try ScratchFoot and give us feedback on any bugs they find, and the effectiveness of using this tool to help students transition from Scratch block programming to text programming in Java. However, we are eager to get the word out that this tool exists. ) ScratchFoot is currently at version 0.5 and has not been tested publically – so use at your own risk. (They have also introduced a new version that uses a new language – Stride – with simpler syntax.) Greenfoot is similar to Scratch in that it is object-oriented (each object on the screen has scripts/variables associated with it), they have an x/y location, point in a certain direction, can detect collisions, detect key presses and mouse presses, use cloud variables, etc. In many ways it is similar to Scratch, but it is text-based, and pure Java. (Greenfoot is a Java-based IDE for education. It does not currently work with Greenfoot Stride (although we hope to secure funding (from somewhere) to continue this work and make a Stride version available). ScratchFoot is available now from github at ScratchFoot is compatible with Greenfoot 3.x Java. ScratchFoot includes 1) a library that offers a Scratch-like API in Greenfoot, and 2) a tool to automatically port a Scratch Project over to a Greenfoot Scenario. If a class is specified as a parameter, only objects of that class or its subclasses will be returned.We are excited to announce the availability of ScratchFoot, a Scratch emulation layer in Greenfoot.

Images of type ‘jpeg’, ‘gif’ and ‘png’ are supported. True if the mouse has been pressed changed from a non-pressed state to being pressed on the given object. The image may be used to draw onto the world’s background. Return the y-coordinate of the object’s current location. Any previous text shown at the same location will first be removed. If called on an already looping sound, it will do nothing. Returns the image used to represent this actor. Set the paint order of objects grefnfoot the world. If more than one object of the specified class resides at that location, one of them will be chosen and returned. German translations are available for some videos thanks to Frajo Ligmann. This method can be overridden to implement custom behaviour when the execution is started.

One of the most important aspects greenfkot this class is the ‘act’ method. If the sound is already playing once, it will start looping instead. IllegalArgumentException Set a background image for the world from an image file. If the sound is currently paused, it will resume playing from the point where it was paused. The value returned is the horizontal index of the actor’s cell in the world. Zero degrees is towards the east right-hand side of the worldand the angle increases clockwise. All cells that can be reached in the number of steps given in ‘distance’ from this object are considered. This method is called by the Greenfoot system when this actor has been inserted into the world. The UserInfo class can be used to store data permanently on a server, and to share this data between different users, when the scenario runs on the Greenfoot web site. A number between represents the current sound volume. Return all the objects that intersect this object. All Classes (Greenfoot API)Īct method for world. Get all the objects in the world, or all the objects of a particular class. The act method is called by the greenfoot framework to give actors a chance to. World(int worldWidth, int worldHeight, int cellSize, boolean bounded).
