MouseMoveTrigger is an event trigger which fires when the mouse cursor is moved (MouseMoved). If buttons are given, it only matches events with those buttons. See new for details.
Create a new instance of MouseMoveTrigger.
The buttons parameter determines which mouse buttons can be held down and still match this trigger. It can be one of:
:any. Matches if zero or more buttons are held.
:none. Matches when zero buttons are being held.
:mouse_left, etc. Matches when at least the given button is being held.
An array of :mouse_* symbols. Matches when exactly all buttons in the Array are being held, and nothing else.
Example:
# Matches all MouseMoved events, regardless of buttons: MouseMoveTrigger.new() MouseMoveTrigger.new( :any ) # Matches only if no buttons pressed: MouseMoveTrigger.new( :none ) MouseMoveTrigger.new( [] ) # Matches if left mouse is held down, maybe with others: MouseMoveTrigger.new( :mouse_left ) # Matches if ONLY left mouse held down, nothing else: MouseMoveTrigger.new( [:mouse_left] ) # Matches if BOTH left AND right mouse are held down, nothing else: MouseMoveTrigger.new( [:mouse_left, :mouse_right] ) # Matches if EITHER left OR right mouse are held down: OrTrigger.new( MouseMoveTrigger.new(:mouse_left), MouseMoveTrigger.new(:mouse_right) )
# File lib/rubygame/event_triggers.rb, line 594 def initialize( buttons=:any ) @buttons = buttons end
Returns true if the given event matches this trigger. See new for information about how events match.
# File lib/rubygame/event_triggers.rb, line 602 def match?( event ) if event.kind_of?( Rubygame::Events::MouseMoved ) ((@buttons == :any) or (@buttons == :none and event.buttons == []) or (_buttons_match?(event.buttons)) or (event.buttons.include?(@buttons))) else false end end
