'ss' if this CatanaState creates a single nucleic acid strand 'ds' if this CatanaState creates a double nucleic acid strand
Do nothing
False
Starts the creation of a nucleic acid strand
True
If the creation of a nucleic acid strand is taking place, update it based on the mouse position Do nothing otherwise
True if the creation of a nucleic acid strand is currently taking place False otherwise
Do nothing
Cleans up side effects
If a lattice cell is being picked, highlight it visually Do nothing otherwise
False
Cancel the creation of a nucleic acid strand if 'Escape' is pressed
True if a nucleic acid strand is currently being created AND 'Escape' is pressed False otherwise
Stops the creation of a nucleic acid strand Or does nothing if no creation of a nucleic acid strand is taking place
If the right conditions are met (see 'CatanaState.done()'), this state will clear any side effects and exit itself
True if a creation of a nucleic acid strand is currently taking place False otherwise
Forwards a click_left event to the subclass, and returns its result
true if further actions should be blocked; or false otherwise (action propagates)
The description of this state. This information is retrieved from the subclass May return an empty string if the subclass provides no description
Signals to CatanaActions (see catana-actions.ts) that this state should be exited This is particularly useful for changes in UI elements that are related to a CatanaState
False if SHIFT is currently being pressed True otherwise (state was exited)
Forwards a down_left event to the subclass, and returns its result
true if further actions should be blocked; or false otherwise (action propagates)
Forwards a drag_left event to the subclass, and returns its result
true if further actions should be blocked; or false otherwise (action propagates)
Called when this state is entered. Forwarded to the subclass
Called when this state is exited. Forwarded to the subclass
Forwards a hover event to the subclass, and returns its result
true if further actions should be blocked; or false otherwise (action propagates)
True if 'key' is "Shift"
Otherwise,the keyDown is forwarded to the subclass, and its result is returned
True is then returned if further actions should be blocked. False is returned otherwise (action propagates)
Forwards a up_left event to the subclass, and returns its result
true if further actions should be blocked; or false otherwise (action propagates)
