Math sin expression problem-3

[Suraiya A]

Hi,

I cant write expression. But I try to. I dnt know how can I write this, because what I wrote is not giving me my expected result.

I want the circle to stay  beside the clock. and I linked the circle's Y position movement with the rotation of the clock hand. but the X axis of the circle is in weird position.  how should I write the expression to keep the circle's X positon fixed or whereever I want it or just beside the clock but only Y should be take its value from the rotation of the clock hand.

Please guide me.

Your dimensions are separated, so you should return only a single value and not an array.

just return temp value

I am very slow at picking clue,  face palm, I dnt understand wht u said. what should I write? 

temp = Math.sin(thisComp.layer("rotating hand").transform.rotation / 5) * 100;

[temp [value]];

this??

just return:

Math.sin(thisComp.layer("rotating hand").transform.rotation / 5) * 100;

It doesnot work!!!   I attached kindly check!! the circle goes some weird position if I write this! 

[Airweb_AE]

Try this:

Math.sin(degreesToRadians(thisComp.layer("rotating hand").transform.rotation - 90)) * 100

Yours last expression makes the circle comes down a lil bit. In the meantime I googled  and found another tutorial, and from there I picked the essence and this brings down the circle a lot-- 

x = thisComp.width/2;
y = Math.sin(thisComp.layer("hand").transform.rotation /10) * 400 + thisComp.height/2 + 50;

but the x position of the circle is still fixed. cant move it freely.I wonder why its fixed.

The calculation depends on the animation you want to create with the expression I gave you.

When the "rotation hand" layer's angle is 0°, the "sun" layer is at the top, and when the angle is 180°, the "sun" layer is at the bottom.

Yes, the rythm is very cute. The rythm is like a Monk is floating. I like it. but Its still staying at the edge, It dsnt come down and stay beside the clock!!! 😮 why!! I want the cute ocilliation from your expression but also the sun/circle needs to be beside the clock.

[Airweb_AE · Accepted solution]

If you want the sun to be next to the clock, adjust the X position of the sun.

You can also adjust the amplitude.
