Floating expression

[Filip Vandueren]

This could be a starting point, but it will be nicer to animate it by hand so it gets a bit more random.
I’m assuming 2D layers:

position:

sp=2;
amp=150;
gravity = 50;
x = Math.sin(time*sp)*amp;
y= time*time*gravity;
value + [x,y];

rotation:

sp=2;
amp=5;
x = Math.sin(time*sp)*amp;
value – x;

Simple and amazing expression! I was needing something like this also.

Here’s an old Dan Expression for what you want:

Wow – this is great!

I need to modify it slightly for a project. I have many objects falling, so I need to introduce some element of randomness to the mix so the objects are not all moving the same. In addition, I need the items to be “blowing” to the side as they fall, so I need to introduce some lateral movement. Can anyone give me a hand? Thanks!!!

I just start learning AE , and am now trying a little more fancy effects . I am trying to make this floating effect works on a layer imported from photoshop . Then I found this post saying

position:

sp=2;
amp=150;
gravity = 50;
x = Math.sin(time*sp)*amp;
y= time*time*gravity;
value + [x,y];

rotation:

sp=2;
amp=5;
x = Math.sin(time*sp)*amp;
value – x;

But I have no idea where to go to change these parameters , since when I open the position and rotation menu under the layer , there’s none of this options . Sorry if this sounds a little stupid , but where are these commands ?

All you have to do is Option/Alt click the stop watch that is right beside “Position” or “Rotation” under transform, and adjust the parameters to your liking. =)

Hey,

This is pretty cool, but i was wondering if a few extra things can be done.
I am looking for an expression that will animate the falling leaf and then slow the movement down until the leaf finally falls to the floor (which is about half way down the screen). Is there anyway to control the length of this animation. I know i’m asking for a lot, but any help would be appreciated.
