To check an ECS component enabled state on the main thread, use EntityManager.IsComponentEnabled<T>(entity) to read the enabled bit and branch logic for imperative decisions like state machines or pickup workflows.

IsComponentEnabled checks the enabled bit of an IEnableableComponent, while HasComponent only checks structural presence. Using HasComponent instead of checking the enabled state can cause silent logic bugs in conditional workflows.

No, EntityManager.IsComponentEnabled is restricted to the main thread. For job or parallel contexts, you should avoid this approach in favor of using EnabledRefRO<T> and query filters to read component state.

You can toggle an enableable component state by pairing EntityManager.IsComponentEnabled<T> to read the current bit, then using SetComponentEnabled<T>(entity, bool) on the main thread to enable or disable the targeted behavior.

You need to check enabled state when making imperative main-thread decisions such as pickup and drop logic, conditional enable/disable sequences, or state machines where the active behavior depends on the component bit rather than structural existence.
