I am creating a new game. I need a code which adds object from one place every few seconds. The name of the actor where its going to come from is Tutankhamun and the actor spawning is called Bee. Could someone help me with the code. The world is called Desert.

In the Tutankhamun class you can write

Bee bee = new Bee();
getWorld().addObject(bee, getX(), getY());

Use a timer. When the timer reaches its target value spawn a Bee and reset the timer value.

/* class Tutankhamun */
private int spawnTimer = 250
// in act
spawnTimer--;
if (spawnTimer == 0) {
    getWorld().addObject(new Bee(), getX(), getY());
    spawnTimer = 250;
}

Now the problem is that when i put the code for randomly moving the bees in the actor bee it doesn't move but it goes crazy.

move(2);
       if (Greenfoot.getRandomNumber(100) < 10)
       {
           turn(Greenfoot.getRandomNumber(90) - 45);
       }   
       if (getX() <= 5 || getX() >= getWorld().getHeight() - 5)
       {
           turn(180);
       }
       if (getY() <= 5 || getY() >= getWorld().getHeight() - 5)
       {
           turn(180);
       }

i changed the second getHeight into getWidth but it still doesn't work.

move(2);
       if (Greenfoot.getRandomNumber(100) < 10)
       {
           turn(Greenfoot.getRandomNumber(90) - 45);
       }   
       if (getX() <= 5 || getX() >= getWorld().getHeight() - 5)
       {
           turn(180);
       }
       if (getY() <= 5 || getY() >= getWorld().getWidth() - 5)
       {
           turn(180);
       }

Guys, is there a code i can add to the previous codeof spawning the characters every few seconds where i can limit the amount of bees spawning.

/* class Tutankhamun */
private int spawnTimer = 250
// in act
spawnTimer--;
if (spawnTimer == 0) {
    getWorld().addObject(new Bee(), getX(), getY());
    spawnTimer = 250;
}

This is the code where i want the code to limit the amount of bees spawn

Well, if you wanted to limit the number of bees in the world to, say 50, then you could use:

// in act
if (spawnTimer > 0) spawnTimer--;
if (spawnTimer == 0 && getWorld().getObjects(Bee.class).size() < 50)
{
    getWorld().addObject(new Bee(), getX(), getY());
    spawnTimer = 250;
}
