Player states

The player character has a wide variety of behaviors, such as jumping, running, and crouching. Coding such behaviors can become very complex and hard to manage. One solution is to use Boolean variables (is_jumping or is_running, for example), but this leads to possibly confusing states (what if is_crouching and is_jumping are both true?) and quickly leads to spaghetti code.

A better solution to this problem is to use a state machine to handle the player's current state and control the transitions to other states. Finite state machines were discussed in Chapter 3, Escape the Maze.

Here is a diagram of the player's states and the transitions between them:

As you can see, state machine diagrams can become quite complex, even ...
