Object interaction with expressions
Hello expression masters,
I’ve been asked to investigate the possibilities to use collision detection in After effects. I got two approaches that I want to check if they’re possible to do (I’ll try and explain this as clear as I can).
1. Is it possible for one object to “push” other objects.
2. Is it possible when an object scales to define the scale/size of other objects around it.
Basically I want interaction between objects.
Thanks for any help!

Hello Kim,
I’d say this is is possible, but very difficult, and it could require a lot of code.
In essence it’s writing a foam system.Is it meant to be as simple as your example:
4 shapes, you know in advance which of them will be the “pusher”, and they have a mathematically defineable shape ?Are they meant for many or long animations, so you’re unable to fake it by keyframing ?

Kim,
I have an example of the second situation in our Meeting 002 project found at the following link: https://web.mac.com/pxlguy/iWeb/DallasAEUG/Meeting%20Project%20Files.html
Look under the expressions folder for the Dynamic comp.

Hey,
thanks for your responses.
Filip: unfortunately not as simple as my illustration. I will have quite a few symbols/illustrations that needs to be affected. Perhaps I am better off keyframing then?
My knowledge in expressions is limited, so writing a foam system is not an option for me 🙂Pxlguy: thanks! This solves one part of my question.
Again, thanks for your responses!
