Class Rubygame::EventTriggers::KeyReleaseTrigger
In: lib/rubygame/event_triggers.rb
Parent: Object

KeyReleaseTrigger is an event trigger which fires when a key on the keyboard is released (i.e. KeyReleased).

NOTE: This trigger is identical to KeyPressTrigger, except that it fires for KeyReleased instead of KeyPressed. Please see the documentation for KeyPressTrigger for info about the parameters and behavior of the trigger.

NOTE: This trigger only works with the new-style KeyReleased event class, not with the older KeyUpEvent. See EventQueue#enable_new_style_events
