There is an act method defined in the greenfoot.World class. You can override it (just like it is done in a class extending greenfoot.Actor) in your TitleScreen class. It is just not provided by the World subclass template as it is when you create a new subclass of Actor.

minnow is of type Actor but, nearest is of type Minnow. You need to typecast minnow as type Minnow in order to set it to nearest. That is, line 13 needs to be as follows: <Code Omitted>Also, your method is supposed to return the nearest minnow; not the last one in the list.

ok thank you

In line 3, you need to typecast the world as a GameWorld object (just as in line 2). To avoid double work, you can set the world to an object reference variable prior to line 2: <Code Omitted>It allowed for the rest to be pretty short as one line, so I combined your lines 2 and 3 as my line 3.

Thanks a lot

This may not be quite so easy to do. Remember that both the asteroids and the rocket are drifting/moving. It may not be enough just to change the direction of a colliding asteroid. In my asteroids scenario, which has shielding implemented, I had both colliding actors change their trajectories with the help of a smooth moving system. You may want to take a look at its codes -- especially the

No.

What have you tried?

great, thank you

Well, get that much done so you have something to work with.

The mouseClicked method does not look for clicks on classes. It looks for clicks on a specific object (or any click when the argument is null). If the code given is in your Block class you can use this as the argument. For the world, you can simply use getWorld() for the argument.

Aaa hahahah okey xd

The bounds are determined by the dimensions of the images set to the actors -- meaning the bounded areas are always rectangular. Yes -- and no. There is no exact center along a dimension o

From restarting alot this is what i really have so far. Other than that i don't know where to go. <Code Omitted>
