Anything in ECSY, or recommended patterns, for handling references between components in different entities?
If I have one-to-many relationship between components (e.g. Foo and GroupOfFoos), what is the best way to implement that in ECSY? Should GroupOfFoos just contain a mutable property that is a Set of references to Foo objects? Or should Foo contain a reference to the GroupOfFoos to which it belongs. Or is there a cleverer more ECSey way to do it?
