How do you make the crab give a certain sound after it turns more than 18 degrees?? It already moves when the left/right keys are pressed. What code do I add? PLEASE HELP!!! public class Crab extends Actor { private GreenfootImage image1; private GreenfootImage image2; private int wormsEaten; /** * Create a crab and initialize its two images. */ public Crab() { image1 = new GreenfootImage("crab.png"); image2 = new GreenfootImage("crab2.png"); setImage(image1); wormsEaten = 0; } /** * Act - do whatever the crab wants to do. This method is called whenever * the 'Act' or 'Run' button gets pressed in the environment. */ public void act() { if (isAtEdge() ) { turn(5); } checkKeypress(); move(5); lookForWorm(); switchImage(); } public void turnAtEdge() { if ( isAtEdge() ) { turn(17); } } public void randomTurn() { if (Greenfoot.getRandomNumber(100) > 90) { turn(Greenfoot.getRandomNumber(90)-45); } } /** * Alternate the crab's image between image1 and image2. */ public void switchImage() { if (getImage() == image1) { setImage(image2); } else { setImage(image1); } } /** * Check whether a control key on the keyboard has been pressed. * If it has, react accordingly. */ public void checkKeypress() { if (Greenfoot.isKeyDown("left")) { turn(-4); } if (Greenfoot.isKeyDown("right")) { turn(4); } } /** * Check whether we have stumbled upon a worm. * If we have, eat it. If not, do nothing. If we have * eaten eight worms, we win. */ public void lookForWorm() { if ( isTouching(Worm.class) ) { removeTouching(Worm.class); Greenfoot.playSound("slurp.wav"); wormsEaten = wormsEaten + 1; if (wormsEaten == 8) { Greenfoot.playSound("fanfare.wav"); Greenfoot.stop(); } } } }

I am trying to have a sound play whenever the crab in my scenario turns more than 18 degrees. This is what I have so far, but I have no idea how to make it so it only plays when it has turned more than 18 degrees. Can someone help me? " /** * Check whether a control key on the keyboard has been pressed. * If it has, react accordingly. */ public void checkKeypress() { if(Greenfoot.isKeyDown("left")) { turn(-4); } if(Greenfoot.isKeyDown("right")) { turn(4); } { Greenfoot.playSound("Whip Crack-SoundBible.com-330576409.wav"); } } "

Hello, I would really like to find a way to set the paint order of individual objects. It would make my forest look much more realistic. Currently I have this: <Code Omitted> etc... Which works for one of my players, but when they both try to move through the forest only one of them can do it at a time. It also looks a bit strange because every tree of that class changes when the actor is near one. The only thing I can think to do is to make each tree a different class but that would be a huge pain in the ass. Not to mention I spent a long time making the trees randomly spawn in so they wouldn't be touching which is why I am using the close variables (if anyone is interested in seeing how to do that let me know, I am just barely starting to learn so there may be an easier way to do it but it took me some time to reason it out so I may just leave it). If anyone can think of a way to set the paintOrder of individual objects please let me know! I am dying to figure it out. Thanks! p.s. I don't think I mentioned the desired effect is to have the actor in front of the tree when the y coordinate is larger than the trees y and behind the tree when it is smaller just in case anyone was unclear on the question or couldn't tell what was going on in my code. What I have now works decently but only for one actor as I mentioned.

I have made a game for school in greenfoot but i can't put it online on our site does anyone know how i can put my game online so that i can use the link on our website?
