Basically the title.
I want to be able to add common aces to a project in order to get around the limitations of behaviors and families not being able to be nested. Since I have a number of families that need access to raytracing, and some of those families have the same objects in them, alot of objects end up having 3-5 los behaviors on them and a similar number of custom movement behaviors.
Nested families or ECS would solve this issue, but apart from that, being able to add common functionality to all objects is also a way to deal.
Without duplicating code, my current workaround (event sheet ecs) is cumbersome and result in object count bloat, necessary and abundant "foreach" loops with picking byuid, and event sheet overhead increase, resulting in poor performance.
