so recently I made a plant that tweens in the direction you walked into it from and I wanted to to look better. I would like to add a wind system to that it sways and looks more alive. I have no idea on how I would implement something like this because I would not be able to have two tweens run at the same time because it would bug out the touch tween. does anybody know how i could make this work
here is my script
