Let the method just return true if the body is there and false if not (the variable touched is dealt with as the other part of the 'if' statement that calls it). The scenario comes with a sound ready for you to use, named 'eating.wav'. The first sound would likely be triggered when the counter is at 0 or 1, and then the second counter triggered at 60 or whatever sounds right. Then you assign certain sounds to certain times in the counter. Another thing about that method is that it really does not do what the name implies, which is making it all the more confusing. Every act cycle, you want to increase this counter by 1. We can make that sound play every time the crab eats a seahorse by adding a single line to our crab class that calls aySound after we remove a. In the 'checkIsTouched' method, change the name of the returning variable, and call this method as part of the conditionals in 'if' statements (or set the returned value to a boolean variable ). Your 'checkIsTouched' method, which you call first thing in your 'isTouched' method destroys any previous value for 'touched'. (3) if toggledOn = true and sound is not playing, then play sound (2) if touched is true and checkIsTouched returns false, then // new seperation Also I have found that Greenfoot cant play the same sound file over and over again, which means that if i keep playing a sound, it doesnt stop itself and start over instead waits for it to finish then start again, and when thats.

(d) if toggledOn = false, then // only needs checked after toggling This book teaches Java programming in an interactive and engaging way that is technically relevant, pedagogically. The tone that Greenfoot plays is currently the one inside the guitar class, which is not what I desired. (c) if toggledOn = true, then // only needs checked after toggling (b) set toggledON = !toggledOn // toggles here (1) if touched is false and checkIsTouched returns true, then // new touch Line 12 (private int i = 0 ): this is rather vague from what I can tell, it has only values '0' or '1' and probably should be something like 'private boolean toggledOn = false '. GreenfootSound sound = new GreenfootSound('Bass2.wav') Īctor body = getOneIntersectingObject(Body.class) Įlse if (body != null & touched = true) We are currently working on a new version, which. * the 'Act' or 'Run' button gets pressed in the environment. play their versions of retro video games created using the Java programming language.
