welcome to the sine/cosine tutorial! you may not know what it is, but we'll show you what they do!
first off, make a value. keep it increasing.
now when you have that done, you can do the fun part. using the sine and cosine.
you now should have a square moving like a circle.
if you want to change direction, go to the first rule. add a set value block, and replace the number in the increase value.
now for the fun part.
i hope this helped!
