Variables

Name Description

Public variable

uint32: 1

 

bIgnoreOwningActor

If true, do not apply force/impulse to any physics objects that are part of the Actor that owns this component.

Public variable

Welcome to the new Unreal Engine 4 Documentation site!

We're working on lots of new features including a feedback system so you can tell us how we are doing. It's not quite ready for use in the wild yet, so head over to the Documentation Feedback forum to tell us about this page or call out any issues you are encountering in the meantime.

We'll be sure to let you know when the new system is up and running.
