Pendulum effect acting as metronome

I have a rectangle that I want to swing like a metronome. The closest effect I see is the Pendulum effect in Emphasis section. Is there a way I can have it turn on the bottom axis instead of the top?

Thanks

You could edit the XML file. This is one of the effects not supported for HTML output, are you aware of that?

Editing that XML is actually pretty easy. Look for the lines defining the Transformation point in the beginning of the file. It is normally set to x=0.5 and y=0. Change the u-value to 1 and you'll have switched the rotation point from the top to the bottom:

<transformationPoint>

<geom:Point x="0.5" y="1"/>

</transformationPoint>

If you turn the rectangle 180°, it will move from the bottom, but the whole rectangle will move up, which should be compensated maybe by adding a short Alpha from 0 to 100% before the pendulum?

Thanks Lilybiri! That did it. If you spin the bar 180, the pendulum acts like a metronome.

Did you try yo edit the XML, very easy fix, I put it in the Gallery as Metronom.XML in case I ever want to reuse it.

If your output is going to be SWF then you could use the Infosemantics Rotator Component widget to achieve this.

Take a look at the first video on this page that shows a metronome effect.
