infinity
Hello all< I wanted to know how I can use particular and draw a looping infinity symbol with expressions. I have particular drawing a infinity symbol using key frames, but I need to do it using expressions. Any ideas on the script my trig is very rusty. Thanks all

All you need to do is add this expression to the XY Emitter Position property:
//Begin Expression
amp = 200; // change this to adjust overall size
startPos = [360 , 270]; //adjust this to move infinity sign
freq = 5; // adjust to make drawing of sign faster
//–
x = amp * Math.sin( time * freq);
y = amp * Math.sin( time * 2 * freq);
[x , y] + startPos
//End expressionIt might be helpful to link things like startPos and freq to sliders so you can adjust them more easily.
