#trigger(*names, &block) ⇒ Object
Creates a context instance method which will apply behaviors to role players before execution and remove the behaviors after execution.
Alternatively you may define your own methods then declare them as triggers afterward.
Example:
trigger :some_event do
# code here
end
def some_event
# code here
end
trigger :some_event
