Method AddComponentForLinkedEntityGroup

AddComponentForLinkedEntityGroup<T>(Entity, EntityQueryMask, T)

Records a command that adds a component to an entity's LinkedEntityGroup based on an EntityQueryMask. Entities in the LinkedEntityGroup that don't match the mask will be skipped safely.

Declaration

public void AddComponentForLinkedEntityGroup<T>(Entity e, EntityQueryMask mask, T component) where T : unmanaged, IComponentData

Parameters

Type	Name	Description
Entity	e	The entity whose LinkedEntityGroup will be referenced.
EntityQueryMask	mask	The EntityQueryMask that is used to determine which linked entities to add the component to. Note that EntityQueryMask ignores all query filtering (including chunk filtering and enableable components), and may thus match more entities than expected.
T	component	The component value to set.

Type Parameters

Name	Description
T	The type of component to add.

Remarks

At playback, this command throws an error if the entity is destroyed before playback, if the entity is still deferred, or if any of the matching linked entities cannot add the component.

Exceptions

Type	Condition
ArgumentException	Throws if the component has a reference to a deferred entity, requiring fixup within the command buffer.
NullReferenceException	Throws if an Allocator was not passed in when the EntityCommandBuffer was created.
InvalidOperationException	Throws if this EntityCommandBuffer has already been played back.
