As said, a state is a collection of
actions.
Actions are executed one after the other in sequence, every frame (unless the action
everyframe parameter is uncheck, see
actions).
When all actions terminate (this means that
all actions of the state have everyframe parameter uncheck), a
FINISHED event is fired by the FSM itself.
To edit a created state (add new actions, change its name and color) see
state tab in
FSM editor topic.
