I'm not so familiar with all this new stuff, but how is BYOND's built-in `turn` procedure not used in the call to `animate`? Or are you just being nitpicky and acting as if "BYOND's `turn`" only refers to `turn(Dir, Angle)` and not also to `turn(Matrix, Angle)`? I thought it was pretty clear what I was asking.
Neither BYOND's turn() nor icon.Turn() are used in this example, although I'm not sure if they round their angles.
I remember Lummox claiming that matrix rotation (which is used in this example), unlike icon.Turn(), does support floats. They don't need to be in [0, 360), either.
I gave credits.
