wyvern.lib.properties
Interface DirectionChooser

All Known Implementing Classes:

AxisShapeChanger

public interface DirectionChooser

This interface is used by the wyvern.lib.properties.Appearance property to request the appropriate directional bitmap for an object. It's used for Nagas, sharks, etc. whose direction depends both on which way they last moved, and possibly whether they're currently horizontal or vertical.

To use a DirectionChooser, add an implementation of it as a property with the name "dirs-appr". The AxisShapeChanger is a DirectionChooser that knows how to do directions for monsters that can change from 1x2 to 2x1 as they move.
