Counter for lives not incrementing or decrementing.

I have a life counter. It's called aCounterLives. This is meant for the lives (numOfBuckets). I'm not why, but I think it's because of the counter's methods. This is the method that deals with the players lives. numOfBuckets is a dynamic variable for now, though I think it being set would likely fix the problem.

           numOfBuckets = numOfBuckets - 1;

You will need to show the initialization and assignment of and the getter method for the aCounterLives object in your MyWorld class.

Basically what I want to do is start with three lives, and then decrease the number of lives by one. The counter will record this.

How about the assigning of an object to the field and the command to create that object? All you have shown is the declaration of the field and the getter method for the value of the field.

I think I have even a bigger problem. My lives (numOfBuckets) won't decrement. The decrementation is in the boomArea class. It has a playerLives method (its return type is void, so maybe that's the problem?) :

    }
This does not work. Would this work?

That's no longer our issue. I've removed all the references to aCounterLives.

What is playerLives actually counting? Or, maybe (to get a better idea of what you are doing), the question should be: do you remove the player from the world each time a bomb hits it, or does it stay in the world?

It's a reference to NumOfBuckets. It's from the getter method getNumOfBuckets in the bucket class.

int playerLives = ((MyWorld)getWorld()).getABucket().getNumOfBuckets();
I remove a life everytime the bomb hits the boomArea. That's what the playerLives method is for.

Then -- the player stays in the world (until all 3 lives are lost)?

Yes. The game is meant to restart when the player loses all of their lives.

Okay. What is the difference between the two int variables playerLives andd playersBuckets?

The first one is a ref to numOfBuckets. The second is there to return how many lives the player has and use it.

The calling method already knows the value it is passing (which is the exact same value that is being returned). I do not get the logic there.

Do you want me to remove the return type and call for the playerLives method?
