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°.

You could change your rotation wiggle() expression to:
w = wiggle(0.2,60);
if (w < 0) w += 360;
wand 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 0°.
…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;Dan

Sorry, that doesn’t work either.

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