Using my 2 brain cells, I figured out a GENIOUS way to code animations
using this formula in poststep:
(e)=>{
math.sin(sim.time / 0.06) > 0 ? {
texture = "[1st image name]"
} : {};
math.sin(sim.time / 0.06) < 0 ? {
texture = "[2nd image name]"
} : {}
}
But all the frames need to be present for the animation to work, so I suggest that you put all the frames in some sort of box like I have in mine and put it to the side
I also made a few other things, plz check out
