Is Falling stays always true

Hello,

I started to learn Unreal Engine a few days ago and hope to find some help here.

I used the third person map and changed the character mesh to a controllable sphere that can roll and jump. At the moment the sphere can also jump when its falling from platform. I want to avoid that.

So i tried to implement the function Is Falling, but it gives always ‘true’ back.

Have I missed something, what am I doing wrong?

Sorry for the beginner’s question, somehow I can’t find the solution that helps me.

Thanks!
