Hello guys,
I need some guidance with something I really cannot understand (or find) a way to make an animation to come into the stage and then stay on screen while scrolling down. I was trying to make an animation come in and stay but if I try to animate the image (or symbol with animation too) to stay on screen forcing it by animating the image go down while scrolling all I get it's a "shaky" image (or symbol) while going down, I found this website that have this tree which stay on screen pretty well and this is basically what I want with my animations to enter on stage and maybe later after some time make the animation go away
