The problem may be a World subclass one. Show its codes.

uhm... how do I get the stored input in the variable college and call the variable in an actor? for example: //in the actor setText("College: "

I figured out how to get it to work. Thanks for the help anyway!

You already have the condition. So you can add: <Code Omitted>Then you need to have a World subclass named GameOver, put the image as the background or do whatever you want to do in that world.

You could check which image is shown right now. If it is one specific image (or even if it is playing the animation at all), check if the actor is intersecting the opponent.

If you have an actor as the parameter, then you would add this actor several times. An actor can only be in a world at one position at a time. You don't want to add one object several times, you want to add several objects of a class.

Then "inv" will stay "null" because it is never changed. Keep the HP of the Invaders in the Invaders class.

You check it just like checking loc. Just replace loc with next.

You call "loseHealth(1)" from the act method of Level 1 which reduces hpE by one every act cycle. But apparently your getter method is already doing that as well. (A getter method should only get the value without changing it so you can get it whenever you want.) It is really weird that you have the variables in your world class. Just imagine you have more than one Enemy, but one variable in the world class trying to make sure all enemies are acting correctly... For the two hpE variables. I can't see anything which could cause it from the code you posted. Maybe there is a duplicate in Screen

There are some 3D engines by now, you just have to search for it. But Greenfoot isn't made for running 3d games, so they are very laggy...

Your Ball code would only need to have the falling speed, not anything else I wrote earlier: <Code Omitted> You would need to add this method to your World code: <Code Omitted> U

Nevermind! The problem was that world ref wasn't correct. It didn't point to the right world, which is Space.

"mainEnemy()" is a method, "mainEnemy" is a variable. In your case, you set "mainEnemy" to a "MainEnemy" object in the world. You want to spawn new actors though. So you can remove line 28 and change "mainEnemy()" in line 30 to "new MainEnemy()". You need to add a call to the method from the act method. I suggest to add the "enemySpawn" method into your world subclass instead, though.

That worked! Thank you so much! :)
