I'm trying to use interfaces, so that I can have two similar types of object, handled by a single "manager" class.

In this instance it's going to be "zombie" and "civilian" both implementing "creature"

One of the member functions, needs another custom type passing in as a parameter, in this case, an array of type "building"
I've managed to get all the methods that use standard objects, and processing objects to work, jsut not with custom ones.

here's a code snippet:
Code:

public interface creature
{
  public void draw(PImage radar);
  public void move(building[] city);
  public boolean hit(float _x, float _y, float damage);
} 

this gives the following error:

Code:

:/Documents and Settings/Administrator/Application Data/Processing/build/Temporary_7679_1028.java:648:20:648:27: Semantic Error: The static type "Temporary_7679_1028$creature" must use a qualified name to access the non-static member type "Temporary_7679_1028$building" of the enclosing type "Temporary_7679_1028". 

Now Java isn't my primary language, so I'm having trouble deciphering the error to know what I need to change about the interface, or about my "building" class to make it available for use, so any pointers will be gratefully recieved.

Jsut tried that, unfortunately, since the draw method requires a PImage, being in a .java tab, makes that break.

I should be able to workaround this, by making the building array global, and accessing that way instead of passing a reference.
