This PR implements an accelerating data structure for changing archetypes. It adds an
edgesfield toArchetypethat maps a component ID to the possible archetypes to move to if you added or removed that component. It can be considered a naive implementation of an archetype graph.With this PR, and with buffering on, I've seen a 40% improvement in insertion speed on 0.9, and a 30% improvement in insertion speed from Matter 0.8. In other words, without this PR 0.9 is 10% slower than 0.8, but with this PR it is 30% faster than 0.8.
