Methods

Name	Description
GetComponentTypeHandle<T>(bool)	Gets the run-time type information required to access an array of component data in a chunk.
GetComponent<T>(Entity)	Look up the value of a component for an entity.
GetComponent<T>(SystemHandle)	Gets the value of a component for an entity associated with a system.
GetSharedComponentTypeHandle<T>()	Gets the run-time type information required to access a shared component data in a chunk.
GetSingletonEntity<T>()	Gets the Entity instance for a singleton.
GetSingleton<T>()	Gets the value of a singleton component.
HasComponent<T>(Entity)	Checks whether an entity has a specific type of component.
HasComponent<T>(SystemHandle)	Checks whether an entity associated with a system has a specific type of component.
HasSingleton<T>()	Checks whether a singleton component of the specified type exists.
IsComponentEnabled<T>(Entity)	Checks whether the IComponentData of type T is enabled on the specified Entity. For the purposes of EntityQuery matching, an entity with a disabled component will behave as if it does not have that component. The type T must implement the IEnableableComponent interface.
IsComponentEnabled<T>(SystemHandle)	Checks whether the IComponentData of type T is enabled on the specified system using a SystemHandle. For the purposes of EntityQuery matching, a system with a disabled component will behave as if it does not have that component. The type T must implement the IEnableableComponent interface.
SetComponentEnabled<T>(Entity, bool)	Enable or disable the IComponentData of type T on the specified Entity. This operation does not cause a structural change (even if it occurs on a worker thread), or affect the value of the component. For the purposes of EntityQuery matching, an entity with a disabled component will behave as if it does not have that component. The type T must implement the IEnableableComponent interface.
SetComponentEnabled<T>(SystemHandle, bool)	Enable or disable the IComponentData of type T on the specified system using a SystemHandle. This operation does not cause a structural change (even if it occurs on a worker thread), or affect the value of the component. For the purposes of EntityQuery matching, a system with a disabled component will behave as if it does not have that component. The type T must implement the IEnableableComponent interface.
TryGetSingletonEntity<T>(out Entity)	Gets the singleton Entity, and returns whether or not a singleton Entity of the specified type exists in the World.
TryGetSingleton<T>(out T)	Gets the value of a singleton component, and returns whether or not a singleton component of the specified type exists in the World.
