Problem with java.awt.Color and java.awt.Font

By ryan22, with 1 reply.
Replied to by danpost, almost 9 years ago:

The newer versions of greenfoot have the 'setColor' and 'setFont' methods using parameters of type 'greenfoot.Color' and 'greenfoot.Font'. Remove the import lines 3 and 4 and replace 'Font.PLAIN' on line 14 with 'false, false' to conform to the 'greenfoot.Font' constructor.

line 1 error, what does that mean

I do not see where 'conn' is being set any object to it (its value remains 'null', which you cannot execute any method on -- hence the error).

ArrayList Help

Okay -- your lists will never contain the same things. The reason being is that you create and add items to one list (in the PackingList class), then, you acquire the other list by using 'getIntersectingObjects' (in the Mannequin class).

Probably best is to create one of each item to start with. Save a reference to each and add a getter method for each. Then the world can get and add each into itself and the PackingList class can add thei

How do I get an actor to slow down when it hits another actor?

You cannot change a hard-coded value (which you currently are using for the speed of the sheep). The value for the speed (currently '2' everywhere for the sheep) needs to be replaced by a variable (a value that can be changed). That variable needs to be maintained by using a field. You will also need a timer field to track the time remaining that the sheep is to run at slow speed.

How do I make the actors in my class randomly pop up?

Let your world control that through its act method.

Is it possible for one actor to call another actor to appear in the game?

If you mean create another actor and add it into the world -- no problem: <Code Omitted>

Is it possible to put all of the ingredients I have touched into an if/then statement? (like if one actor has touched a specific amount of other actors do..., else...)
