#map_controls(input_hash) ⇒ Object

map_controls is to be setup outside of an actor and passed in at construction time ie:

mapper.map_controls 

'+a' => :jump,   # emit jump when 'a' is _pressed_
'-b' => :duck,   # emit duck when 'b' is _released_
'c'  => :block   # emit block when 'c' is _pressed_ AND _released_

all keys will have a <key_name>? defined for checking state at anytime create_actor :fighter, input: mapper

all of the actor’s behaviors can / should use the input mapper instead of raw key bindings
