Start and stop oscillating animation

Hy,

In this applet https://www.geogebra.org/st...

I would like few things:

Control animation with button (button is scripting Check box, and animation goes only when check box is true) ... and it is OK.

But I would like that animation stop when slider is on beginning, and then again start with pressing button

I tried

scripting button (rot is slider) and slider (animacija is Chech box)

Button

rot=rot+0.01

animacija=!animacija

And in slider speed

If[animacija ∧ (rot > 0), 1, 0]

And it is not ok. Slider is going back and it is not going forward, and is on 0. And that means that animation stops.

Only if I hit button twice or three times it start going forward.

Is anyone have some better idea?

Here is ggb file.

Hi,

Button

animacija=true

And in slider speed

If[animacija , 1, 0]

are enough because the stop is made but the rot's update .

animacija is all that is needed in speed.
