![]() So, I thought it was a natural choice to attempt to create a way to move students from Scratch to Java. ![]() ![]() Greenfoot's functionality and model is similar to Scratch in many ways: the basic “object” is a Sprite/Actor, there is a 2-d canvas collision detection multiple costumes/images etc. The motivation is to provide a more gentle way for students to transition from block-based languages like Scratch to “real-world” text-based languages, like Java. Removed by moderator - please do not share personal information on Scratch Victor Norman (vtn2), and student Jordan Doorlag, at Calvin College (). 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. When lobster eats crab, call aySound (“au.We are excited to announce the availability of ScratchFoot, a Scratch emulation layer in Greenfoot.When crab eats worm, call aySound (“slurp.wav”).There are 2 sound files included in the crab scenario.Look at the Greenfoot documentation and find the method that is used to play sound.Put Greenfoot.stop() line in the Lobsters lookForCrab method, after it “eats” crab.The crab is removed and the game should stop when the Lobster eats the crab.If it doesn’t work, try somewhere else.Try putting the line of code in, and run.Where can we put a call to this method so that it will stop the execution when the lobster eats the crab?.In Method summary find a method that stops the execution of the running scenario.Choose Greenfoot Class Documentation from the help menu.String literals: Strings enclosed in double quotes.Strings are characters (letters, numbers, symbols) that are put together to form words or sentences.Greenfoot has a method to tell whether or not a key is being pressed: static boolean isKeyDown(String key) What is the return type? What is the method name? What is the parameter?.
