Method SetComponent

SetComponent<T>(Entity, T)

Sets the value of a component of an entity.

Declaration

public static void SetComponent<T>(Entity entity, T component) where T : unmanaged, IComponentData

Parameters

Type	Name	Description
Entity	entity	The entity.
T	component	The data to set.

Type Parameters

Name	Description
T	The component type.

Remarks

Use this method to look up and set data in another entity using its Entity object. For example, if you have a component that contains an Entity field, you can update the component data for the referenced entity using this method.

When iterating over a set of entities with an idomatic foreach query, don't use this method to access the data of the current entity in the set. It's faster to access the data by requesting it as an argument of a query.

When you call this method gets replaced with component access methods through ComponentLookup<T>.

In both cases, this lookup method results in a slower, indirect memory access. When possible, organize your data to minimize the need for indirect lookups.

Exceptions

Type	Condition
ArgumentException	Thrown if the component type has no fields.

SetComponent<T>(SystemHandle, T)

Sets the value of a component of an entity associated with a system.

Declaration

public static void SetComponent<T>(SystemHandle systemHandle, T component) where T : unmanaged, IComponentData

Parameters

Type	Name	Description
SystemHandle	systemHandle	The system handle.
T	component	The data to set.

Type Parameters

Name	Description
T	The component type.

Remarks

Use this method to look up and set data in another system owned entity using its SystemHandle object.

When you call this method gets replaced with component access methods through ComponentLookup<T>.

Exceptions

Type	Condition
ArgumentException	Thrown if the component type has no fields.
