Method RemoveComponent
RemoveComponent(NativeArray<Entity>, in ComponentTypeSet)
Removes multiple components from a specified colleciton of entities.
Declaration
public void RemoveComponent(NativeArray<Entity> entities, in ComponentTypeSet componentTypeSet)Parameters
| Type | Name | Description |
|---|---|---|
| NativeArray<Entity> | entities | The collection of entities to modify. |
| ComponentTypeSet | componentTypeSet | The types of components to remove. |
Remarks
You can use this method to remove a component from an Entity
It's OK if some or all of the components to remove are already missing from the entity.
Removing components changes an entity's archetype and results in the entity being moved to a different chunk.
If any of the types are a managed component which implements IDisposable, this operation will invoke Dispose() on the component value.
Important: This method creates a sync point, which means that the EntityManager waits for all currently running jobs to complete before removing the component. No additional jobs can start before the method is finished. A sync point can cause a drop in performance because the ECS framework might not be able to use the processing power of all available cores.
Exceptions
| Type | Condition |
|---|---|
| ArgumentException | The Entity does not exist. |
