  • Linking rotational value correctly to a compass graphic

    I’ve been racking my brains trying to figure out how to correctly link a number value to a rotating compass graphic (using a basic wiggle) so that the values are between 0° and 360° (or 359° and then it changes to 0 if it’s 360°) rather than using minus values.

    Can anyone help?

    21° is correct.

    -30° is incorrect – this should be 330°.

    Project file:
    13937_compass.aep.zip

    -thisComp.layer("Dial").transform.rotation[0].toFixed(0)+"°"

    You could change your rotation wiggle() expression to:

    w = wiggle(0.2,60);
    if (w < 0) w += 360;
    w

    and remove the “-” from your text expression.

    Sorry for the late reply Dan, the notification ended up in my spam folder.

    Thanks for the info, but I’m not quite getting the result I was hoping for.

    I think that the solution might be to try and link the Source Text property to the 2nd value of the Rotation Property, but to ignore the “1x” value and the “-” value.

    For example…


    …ignore “0x” and ignore “” to give 15°.


    …ignore “0x” and ignore “” to give 359°.


    …ignore “-1x” to give .


    …ignore “-1x” to give 30°.

    Does that make more sense?
    Would that be possible?

    The wiggle was used just to test it out. I’ll probably be keyframing these values manually but with a bit of wiggle added.

    Many thanks.

    Maybe like this then:

    w = wiggle(0.2,60);
    w %= 360;
    w += (w < 0) ? 360 : 0;

    Sorry, that doesn’t work either.

    I think you just need to get rid of the “-” operator at the beginning of your text expression.
