ok really? thanks!

Oh, ok. I have made those change. Thanks. Also i found a solution.

Seems like it worked. Thx a lot : )

Remove line 2.

In line 4, you assign a Class type object to a field called object . A class is not a bullet, so you cannot assign object (containing a Class object) to a field that is to retain a Bullet object. Other issues include: * the variable called counter (at line 6) is not used anywhere; so that line is as if not there; * the Bullet constructor Counter parameter is not dealt with in the constructor, so it is as if you passed nothing; I will presume you want to create a new bullet and pass it the Counter object. You will need to show the code of the cla

You will need to show the code about which the method is called and indicate what class that code is in.

You need to split line 94 up into individual lines so that you can make a reference variable to the new world: <Code Omitted>Now you can add to this to add the actor where it is in "this" world: <Code Omitted>It seems to me like all you really needed to do, instead of creating a whole new world, was to use a field to indicate the level and do things based on its value.

//PROBLEM SOLVED I managed to abstract the keys. Thank you all.

How far can you get in the process? There should be a "Share..." button in the top-right. When you click that button, a window should show with three pictures across the top, which are tabs for the different export options. Is the problem that the window doesn't show, or that it's blank when it does show, or that some of the controls are then disabled or unresponsive?

Thanks! It worked :)

You will probably have to override the World act method in the PredatorPopulation class to perform the "ask".

I think lines 5 through 8 in the gameOver method need to be put in the following if block: <Code Omitted>

You have stuff inside the canSee if block in the working one that is outside in the not working one.
