Hi, Programmed sketch in DrGeo can be animated, for example like the script bellow. The "canvas do:" message forks the block so user is not blocked. At #udpate message the items and views (morph) are recomputed and refreshed . Before porting DrGeo to Athens, the animation was pretty fast, now it is very slow. Any idea from where it could come from? Thanks ---8<------ |canvas s stats points| points :=Array new: 12. stats := Array new: 12 withAll: 0. canvas := DrGeoCanvas new. 2 to: 12 do: [:i | points at: i put: (canvas point: i@0.1).
