Very Odd Bug

Stupid Programmer Trick # 38,298,987,234

The first component to start moving was shorted by one second. Had nothing to do with the quadrant.

In this script:

load( Sketchup.find_support_file('sketch_talk.rb', 'Plugins/ruby_console_pro/') )
n
box o, [20,20,0], 10
box1 = g 'box1'
m box1, [20,20,30], 0, 20
none

box o, [-20,-20,0], 10
box2 = g 'box2'
m box2, [-20,-20,30], 4, 20
none

box o, [-20,20,0], 10
box3 = g 'box3'
m box3, [-20,20,30], 8, 20
none

box o, [20,-20,0], 10
box4 = g 'box4'
m box4, [20,-20,30], 12, 20
none

go

four boxes are created in the four rg quadrants. Translating SketchTalk to English, that's:

n # select all, delete (quickie File/New)
box o, [20,20,0], 10 # Rectangle, origin to [20,20,0], PushPull up 10
box1 = g 'box1' # Create ComponentInstance named 'box1'
m box1, [20,20,30], 0, 20 # schedule a future move during seconds 1 through 19
none # unselect everything

...
go # begin the scheduled moves

Each box schedules a move, 20 units out into its quadrant and 30 units up the blue axis. They move, which is great.

But the box in the positive r, positive g quadrant doesn't quite do a full move. The move code is quite simple-minded. It divides the move vector into distance per frame. It has nothing to do with quadrants.

    def create_amcis() # convert registrants into actionable, movable CIs
        for reg in @@registrants
            duration = reg.stop - reg.start
            frames = duration * $sketch_talk_fps
            r = reg.vector[0].to_f() / frames
            g = reg.vector[1].to_f() / frames
            b = reg.vector[2].to_f() / frames
            reg.actionable = Con_Amci.new( reg, r, g, b )
        end # registrant loop
    end # of create_amcis()

The move vector is [20,20,30]. Actual move is speed-dependent:
5 sec. [16,16,24]
10 sec. [18,18,27]
20 sec. [19,19,28.5]
40 sec. [19.5,19.5,29.25]

The other three boxes animate happily to a full [20,20,30]. Shuffling the box order doesn't change the behavior. The box in the positive red, positive green quadrant doesn't do a full move.
