Method AddComponentData

AddComponentData<T>(EntityManager, Entity, T)

Adds a managed component to an entity and set the value of that component.

Declaration

public static void AddComponentData<T>(this EntityManager manager, Entity entity, T componentData)
    where T : class, IComponentData

Parameters

Type	Name	Description
EntityManager	manager
Entity	entity	The entity.
T	componentData	The data to set.

Type Parameters

Name	Description
T	The type of component.

Remarks

Adding a component changes an entity's archetype and results in the entity being moved to a different 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.

Exceptions

Type	Condition
ArgumentException	The Entity does not exist.
