Method MoveComponent

MoveComponent<T>(EntityManager, Entity, Entity)

Safely move a managed component on the source entity to another destination entity.

Declaration

public static void MoveComponent<T>(this EntityManager manager, Entity src, Entity dst) where T : class, IComponentData, new()

Parameters

Type	Name	Description
EntityManager	manager	This entity manager.
Entity	src	The Entity the managed component will be removed from. This entity must have a component of type T.
Entity	dst	The Entity the managed component will be added to. If this entity already has T with a different value than src, the existing value will be removed and disposed before the new value is assigned.

Type Parameters

Name	Description
T	The managed component type.

Remarks

If the source and destination entity are identical, no operation is performed.

This operation seems similar to

value = GetComponentData<T>(src); AddComponentData(dst, value) RemoveComponent<T>(src)

But for managed components which implement IDisposable, calling RemoveComponent will invoke Dispose() on the component value, leaving the destination entity with an uninitialized object.``` This operation ensures the component is properly moved over.
