match() should work for objects and return matched object params #2

Closed nylki closed 8 years ago

nylki commented 8 years ago

Returning matched objects in context sensitive L-Systems is useful if you want to modify those (neighboring) objects. For example nutrients trickling up a tree: you may check if a leaf L has a branch F via F<L. That L could the syphon some virtual F.water of that into itself (L.water) for example, to simulate nutrition flow.

implemented in https://github.com/nylki/lindenmayer/commit/212c6d7b3d64bb9eae7a46c126d97f61e1d74a81

However modification naturally works only for the right side of, as the left side got already processed by the L-System.
