In the hunter zombie class, it would be a bit different: <Code Omitted>

I was not trying to correct you. I was just trying to put the spawn rate back to the initial setting (which was 50:2000, and i changed to 5:200; and could even be 1:40). I had not realized what you were trying to do until you re-posted on that code. I see now you were changing the spawning y-coordinate so that it does not get removed near the top of the screen. That would have been a simple fix; however, to tell you the truth, I do not particularly care for the Animal class code because it does not take into account the actual size of the object. If the object was very tall, then it wou

Thanks to danpost for your quick help. It works now.

@Jammn3...Did you ever find out how to make wombat lose energy??

What you need to do is pretty well spelled out in the description. Just look over the class APIs for java.util.Random, java.util.ArrayList and the interface java.util.List to determine what other methods (not specified above) you might need. Also, note what constructors are available for the classes. Java APIs

The first two ways should not be causing that error (maybe in something else you are doing, however). And any of the above ways will not add time between the adding of the new actor. You will need an int spawnTimer to control the duration of time waited to spawn the new actor.

Thanks for the help. Gonna go ahead and try it out.

Thanks! You've been a great help.

I just re-arranged the code, and I found solution, but involves not using the 'null'.

You need to show some effort. Post some attempted code. You may want to browse the Java tutorials, especially the first two sections on Learning the Java Language.

I posted a reply to this in my Progress bar/Health bar scenario comments.

Add an instance integer field to be a life counter in the world class. Initialize its value to 2. In the world act method (or a method it calls), check to see if Crab is in the world, if not, decrement the life counter and then check its value; if the value is not zero, add the crab back into the world; otherwise start a new instance of the world. You may prefer to add the same Crab object back into the world after the first life is gone because the field holding the number of worms eaten will be zero if you add a NEW Crab object into the world. To accomplish this, add an instance Crab fi

You need to track the state of the control key by adding an instance boolean field (I will call it controlDown). <Code Omitted>
