To remove components from an entity, use the EntityManager for the World that the entity is in.
Important
Removing a component from an entity is a structural change which means that the entity moves to a different archetype chunk.
From the main thread
You can directly remove components from an entity from the main thread. The following code sample gets every entity with an attached Rotation component and then removes the Rotation component.
Because removing a component from an entity is a structural change, you can't directly do it in a job. Instead, you must use an EntityCommandBuffer to record your intention to remove components later.
