Personally I’d create 2 custom Events that execute the logic. One for off and one for on.
In your Animations create anim notifies. Have those notifies call the events. You’ll need to add these notifies to every dodge animation.
You’ll need to also setup logic that will reinstate collision if the montage is interrupted.
On a side note you need to upgrade to Enhanced Inputs. The old Axis/Action mappings approach is deprecated. Eventually it’ll be removed… maybe in 5.2
