  Particles or Shapes flowing in a confined area

  Posted by Adam Lewen on December 22, 2019 at 3:55 pm

  Hi there. I am trying to achieve something pretty straight forward but heaving difficulties.
  I have several shapes
  
  and IN these shapes I want to have small vector shapes flying around ( slowly and randomly).
  I would like to have the shape’s bounds (those larger ones containing the small vectors inside) as borders to the particles.
  (imagine those red dots flying in tha blue shape, bouncing around…
  
  I have done this in the past.

  I have started messing with a trial of Newton, Physics Now…But I am sure there is a much simpler ways of achieving this!

  Is there a particle system in AE where I can assign a mask as a bounce boundary for costume particles?

  Tired and lost today and will appreciate any tip!
  Thank you!

  I’m not in front my pc at the moment, but I’m fairly certain Particle Playground has the ability to use a mask at a boundary/wall to contain particles. It’s a bit render heavy, but should do what you’re after.

  Hi. Thanks for the reply.
  Particle Playground does have the ability indeed. I delved into it after writing on the forum.
  As you wrote it’s a bit heavy, but works.

  It can also be achieved with 3rd party plugins such as Newton, or Trapcode.
  For my purposes, I am not sure, I have a couple of dozen shapes containing those ‘hit detection mini-shapes’

  Thanks
