Chapter 3 book work question 2

If I were to design a movement system for my game being designed in my head the context sensitive actions would be based on a button press and less upon the distance from an object. Aside from the necessary actions of opening a door and picking up an object. My characters movements would be based on the state of motion he is in he would not be able to long jump or flip on account of his injured leg, but he will perform a tackle move to bust open doors wich he would use a lot in the beginning of the game  where he is helpless and has know weapon and must run. The use of his weapons would be accessed not from a menu but from the arrangements of weapons on his back to make it fluid and you'll always see the menu.
