Hi gentlemens.

I need a variable that has an oscillation number going back and forth from -x to +x.

To be honest, I am by far no math wiz, but..

SIN(0) seems to be the answer but I can not get it to work.

I suppose I have to use an every tick update, but I only get a static number?

Thanks!

I have tried that - I am doing following:

"Have a variable called 'SinWave'

On Every Tick - Set SinWave to Sin(2)"

Still comes up with a static number.

Sin(2) is always the same number. You need two variables SinWave and Counter.

On every tick you can add for example 0.5 (or any other number) to variable Counter, then SinWave set to Sin(Counter)
