This is my code for the bullet and it causes it to disappear but my game suddenly stops. Help? public void deleteStinger() { if(atWorldEdge()) { getWorld().removeObject(this); } } public void act() { setRotation(direction); move(speed); move(5); checkCollision(); deleteStinger(); }

There is no error message. The game literally pauses for some reason.

What class does the Stinger class extend?

The stinger class extends the animal class in order for atWorldEdge to work. Here is all the code for the stinger and Bee2 (enemy) classes. import greenfoot.*; import java.util.List; /** * Write a description of class Ladybug1 here. * * @author (your name) * @version (a version number or a date) */ public class Bee2 extends Actor { private int beehivesEaten; private GreenfootImage image3; private GreenfootImage image4; /** * Act - do whatever the Ladybug1 wants to do. This method is called whenever * the 'Act' or 'Run' button gets pressed in the environment. */ public Bee2() { beehivesEaten = 0; image3 = new GreenfootImage("bee.png"); image4 = new GreenfootImage("bee2.png"); setImage(image3); } public void act() { followBeehive(); lookForBeehive(); switchImage(); } public void followBeehive() { turnTowards(150,500); Actor beehive = (Actor) getOneIntersectingObject(Beehive.class); move(3); } public void attackBeehive() { if(!getObjectsInRange(500, Beehive.class).isEmpty()) { Actor beehive=(Actor) getObjectsInRange(200, Beehive.class).get(0); if(beehive !=null) { followBeehive(); } } } private void lookForBeehive() { if (isTouching(Beehive.class)) { Greenfoot.playSound("munch.mp3"); removeTouching(Beehive.class); Greenfoot.setWorld(new GameOverScreen()); Greenfoot.stop(); } } public void switchImage() { if (getImage() == image3) { setImage(image4); } else { setImage(image3); } } } // References //www.youtube.com/watch?v=DoElE2f_QdM //www.youtube.com/watch?v=aiNg8ChsyUg //https://www.youtube.com/watch?v=xD98iODedWk //www.greenfoot.org/topics/60455/0 //https://www.greenfoot.org/topics/60455/0 import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo) /** * Write a description of class bullet here. * * @author (your name) * @version (a version number or a date) */ public class Stinger extends Animal { private int direction, speed; public Stinger(int dir) { direction = dir; speed = 5; } public void act() { setRotation(direction); move(speed); move(5); checkCollision(); if(atWorldEdge()) { getWorld().removeObject(this); } } public void checkCollision() { Actor bee2 = (Actor) getOneIntersectingObject(Bee2.class); if(bee2 != null) { getWorld().removeObject(bee2); Fields fields = (Fields)getWorld(); getWorld().removeObject(this); Greenfoot.playSound("splat.mp3"); Counter counter = fields.obtainCounter(); counter.numberCount(+1); // error I had Counter capitalized giving a nonstatic error } } }

Looks like the if in your Stinger class act method should be: because the actor could be removed from the world in the checkCollision method.

Thanks Im in tears right now.

Yes. Lol. I have spent alot of time invested in the game and its finally completed. Its a sigh of relief. However, I still dont understand how myworld can not be equal to nothing.

The method getWorld returns the value of a field that retains the world the actor is currently in. Once you use removeObject(this), that field is set to null. It is not that the world no longer exists; it means that, for all intensive purposes, it does not exist for that actor.
