Emitter contained within object
on Jun 6, 2012 at 2:35:18 pm

Hello,

I am trying to contain some objects from an emitter within a box, etc. I want them to bounce around within a box, circle, or other polygon. I have tried using the repel behaviors, etc... not working for me. Any ideas? (Using Motion 5)

Thanks,

Ed

Use the Edge Collision behavior - in the Simulations category.

Mark..Thanks,

I tried that, but unless I'm missing something, I'm limited to a box. I'd like to have this work within an irregularly shaped object.

That's all you can do

I applied a mask to the group containing the emitter and edge collision behavior. It isn't exactly what I wanted, but close enough. Thanks for you responses.

Ed Bates,

I know your frustration. I had the same problem. As it turns out, Edge Collision is what you need to use, but you just need to know how. Here is a link to a video I made that the particles bounce off the wall.





I cannot tell exactly tell you what I did. Here is a picture of the HUD.

I'm aslo going to give you the link to the project I made. Click on the link and download my Motion project. Once open under the emitter group, you'll find the Edge Collision effect applied.

Play around with the settings I used. Here's the link, https://www.dropbox.com/sh/drpmlmoq932z3df/Babp7FBd4R/Shutter%20Wall Download all the media as well as the Motion project. You should be able to see how the particles bounce off the wall I made.

I hope this really helped,

AJ
