slot refers to property values and you need getter methods (for ReadOnly) and 
getter/setter for ReadWrite property. command refers to actions. In your 
methods, you can access the morph involved in the player using:
    self costume renderedMorph

The tricky part is that you have to choose unique names for slots, commands, 
getters and setters. This is because Player uses a flat name space for all 
slot/command names and methods. This may look simple, but you could have 
packages loaded from outside that could introduce name clashes.

BTW, I mistook you for another Steve in my earlier reply. Sorry.
