Show what you have tried (informing where).
and how to disappear and appear objects from opposite side
Show class code of actor you want to do this to.

public class ball1 extends Actor { /** * Act - do whatever the ball1 wants to do. This method is called whenever * the 'Act' or 'Run' button gets pressed in the environment. */ public int direction = 10; public void act() { move(direction); GameOver(); Actor player_1 = getOneIntersectingObject(player1.class); if (player_1!=null) { if(isTouching(player1.class)) { turn(90+Greenfoot.getRandomNumber(180)); World myWorld = getWorld(); MyWorld myworld = (MyWorld)myWorld; Counter1 counter1 = myworld.getCounter1(); counter1.addScore(1); } } Actor player_2= getOneIntersectingObject(player2.class); if (player_2!=null) { if(isTouching(player2.class)) { turn(90+Greenfoot.getRandomNumber(180)); World myWorld = getWorld(); MyWorld myworld = (MyWorld)myWorld; Counter2 counter2 = myworld.getCounter2(); Counter2.addScore(1); } } if(isAtEdge()){ turn(90+Greenfoot.getRandomNumber(180)); } } public void GameOver() { if(getY() >= 599){ getWorld().addObject(new GameOver(),400,300); } } }

Remove "if (isAtEdge)" block at end of act method. Add the following method to code: 
private void wrapEdges()
{
    int r = getRotation();
    if (getX() == getWorld().getWidth()-1 && (r > 270 || r < 90)) setLocation(0, getY());
    if (getX() == 0 && r > 90 && r < 270) setLocation(getWorld().getWidth()-1);
    if (getY() == getWorld().getHeight()-1 && r < 180) setLocation(getX(), 0);
    if (getY() == 0 && r > 180) setLocation(getX(), getWorld().getHeight()-1);
}
After "move(direction);" in act, add the following line: 
wrapEdges();

For some randomness, you can add something like: 
if (Greenfoot.getRandomNumber(180) == 0) turn (Greenfoot.getRandomNumber(180)-90);

No. Show entire class. Show from the first import statement at top, down to the last character, '}', at the bottom.
