[Moose-dev] CodeCity pan and default color

Hi guys, I was playing with CodeCity. Thanks, Ricky for the effort in porting it to Pharo! I was wondering if there is a way to pan the city? i.e., not rotating around axes, simple 2D pan. I also have a “feature request” (that I already implemented myself): I noticed that the CCColorNormalizer lacks of a “zero” color. In short, when you want to differentiate nodes with weight = 0. For this I implemented a #CCColorNormalizerWithZeroColor (subclass of CCColorNormalizer) that overrides ccValue: anObject | inputValue | inputValue := self transformation ccValue: anObject. inputValue isZero ifTrue: [ ^ self zero ] ifFalse: [ ^ super ccValue: anObject ] #zero is a Color, instance variable of CCColorNormalizerWithZeroColor. Thanks in advance, Roby
