Ok, this may be a bug actually. Consider this (taken from the 3D game I just posted in the arcade):
+Tree -> Set TransformedX to Tree.WorldX - CameraX
This renames ok (if I copy and rename it to the "Grass" sprite object), however ...
+Tree -> Set TransformedZ to WorldDepth - f.Call("RotateZYForZ", distFromHorizon, Tree.TransformedY, WorldTilt)
...does not. It would seem that parameters are ignored. ;) Seems like somewhat inconsistent behavior.
Edit: Again, before anyone calls me out on this, yes, best practice is to use "Self". I just figure consistent behavior is also good to maintain. ;)
