| isReadOnly | Whether the data is only read, not written. Access data as read-only whenever possible. |
ComponentLookup<T> All component data of type T.
Manually gets a dictionary-like container containing all components of type T, keyed by Entity.
Remember to call ComponentLookup<T0>.Update.
When you call this method on the main thread, it invokes ComponentSystemBase.GetComponentLookup.
Prefer using SystemAPI.GetComponentLookup as it will cache in OnCreate for you
and call .Update(this) at the call-site. Also works with IJobEntity and SystemAPI.Query.
