    Hey,

    within a chunk system i have several NativeArray<Entity> with some entities being the root of a LinkedEntityGroup. I want to enable/disable them if the chunk changes visibility state.

    I found those options:
    • EntityManager.AddComponent: provides batch but doesn't obey LinkedEntityGroup
    • EntityManager.SetEnabled: obeys LinkedEntityGroup but doesn't support batch
    Is there a way to get a batched operation which takes account of LinkedEntityGroup?

    Thanks!

    LinkedEntityGroup is buffer. Buffers has AsNativeArray. EntityManager.AddComponent supports native array overload.

    Yep, but that requires a call per entity. There seems to be no recursive method for this, at least i haven't found one.

    you can separate the entities that have LinkedEntityGroup from the ones that don't, and batch vs SetEnabled accordingly.
