Remarks

This function finds all chunks whose archetype satisfies the EntityQuery and adds the specified component to them.

A chunk component is common to all entities in a chunk. You can access a chunk IComponentData instance through either the chunk itself or through an entity stored in that chunk.

Important: This function creates a sync point, which means that the EntityManager waits for all currently running Jobs to complete before adding the component and no additional Jobs can start before the function is finished. A sync point can cause a drop in performance because the ECS framework may not be able to make use of the processing power of all available cores.
