title: NSDictionary sets values for NSMutableDictionary
body: <p>I'm trying to make an rpg style game. I would like to know if and how to make an NSDictionary set the value for a mutable dictionary. The characters in my game will learn moves at different levels and the user can decide which move to use. If more info is needed let me now.</p>
  
  <p>Here's an example</p>
  
  <p>the NSDictionary pulls from a plist of attacks.
  the attacks have names and power values.
  the mutable array will set its attacks to the attacks in the NSDictionary.</p>
