You mean like this? Usually you can check out the Greenfoot API and find a method which you can use. <Code Omitted>

okay

There is a setRotation method in the Actor class.

I could be mistaken, but I think the health bar is for the Bloctopus actor and not for the enemy (which would make a little more sense).

OMG THANK YOU SO MUCH

You could do it by adding boolean fields in the actor classes to indicate their active states; but is seems to me that this is something that the World object should deal with. There are three phases here (a) the first robot performs its task (b) the second robot performs its task and (c) both have completed there tasks. Therefore and int field to indicate which phase is currently being executed would be in order:

You can create an Actor subclass called 'Button', add these buttons to the menu world and pass a variable to them. Then you check if they were clicked and set the world based on the variable then. Or you let the user press a number and set the world based on that.

If you have an Actor subclass named 'Rocket', the line should read: <Code Omitted>

No. But if you want anything to print to the terminal, the 'details' method needs to be called. After that line, you could then add this: <Code Omitted>to print out the field values. I only show this as an example of having the values printed to the terminal -- but, I am quite sure you are wanting to do quite a bit more than that.

A switch statement could also be used here: <Code Omitted>

Hi, I would start by checking the full text of the error message - it probably says more than just "failed to launch". Does it give any indication of what the problem is or what to do?

It will look like this. You can change the numbers to your needs. <Code Omitted>
