Is possible to make the light spot to move in a circular or winding way without using the coordenates on the the effect "CC Light Rays"? I used the "center", but to make something sinuous I must to move dot by dot and the result I don't like very much...
Applying this expression to the Center property will make the light move in a circle around whatever point you choose: value+[20*Math.sin(time*200),20*Math.cos(time*200)]
You can change the 200's to change the speed and change the 20's to change the radius.
Applying this expression to the Center property will make the light move to right while going up and down like a sin wave:
Similarly here, I used 200 for the speed and 20 for the magnitude.
