How do you create a list l and then access a random element of that list?
The
java.util.List
class is abstract, which means you cannot directly create a
List
object from that class. You can create a
List
object via a non-abstract class that extends the
List
class, such as the
ArrayList
class): <Code Omitted>You could import the two packages: <Code Omitted>to simplify the line to: <Code Omitted>

How do I make an Actor follow another Actor?
First, get a reference to the actor it wants to follow; then, turn toward it and move toward it. Depending on your scenario, you may need to reset the rotation of the follower back to zero to complete the steps involved. If the follower moves at a slow rate (certainly, if less than 5 pixels per move), you might consider using a smooth mover support class to eliminate any inaccuracies in moving direction.

In my game, you are supposed to kill all the enemies and go through doors to get to another world. However, that new world is the same world as the starting world, just a new instance. However, when i go through a door, the Health of the player resets. How do i make the health the same as the health in the previous world? << Codes Omitted >>

If I knew what it was, I would have said so. Since I do not, there is nothing to say currently. It could be anything from too many actors in the world to loading music files frequently to who knows what.

is there anyway i can just press a button and it would pop up. << Code Omitted >>
Yes -- but you would not put it in the
Shield
class. The only thing the shield should do is absorb damage and remove itself. Use the Spaceship class'
act
method to put it in: <Code Omitted>

When i try to create a subclass called Villager under my superclass Pedestrian it says "constructor Pedestrian in class Pedestrian cannot be applied to given types" and i dont know whats the issue << Codes Omitted >>
You currently cannot create a
Pedestrian
object (which includes a
Villager
object) without a direction parameter. The simplest way to rectify the situation is to add the following to the
Pedestrian
class: <Code Omitted>Now when created without the direction, it passes control to the constructor w

My Actors dissapear after pressing act or run

It might be because I used the same variables in Attack ( the one that I duplicated) but they are private so I dont think thats the problem And Attack2 is just an object I used to see if it would dissapear as well Its not supposed to actually stay on the Scene
The problem is with the code in your
Attack
and
Attack2
act
methods. The 300 milliseconds is 3/10 of one second -- and, you have the object being removed from the time it was created. Well, the internal clock of the computer continues to run even when your scenario is not running.
