## RemoveComponent\<T>(int, Entity)

Records a command to remove component of type T from an entity.

```csharp
public void RemoveComponent<T>(int sortKey, Entity e)
```

### Parameters

**** (\[int]\(https\://learn.microsoft.com/dotnet/api/system.int32)): A unique index for each set of commands added to this EntityCommandBuffer across all parallel jobs writing commands to this buffer. The [ChunkIndexInQuery](/engine/7000.0/script-reference/unity/entities/chunkindexinquery.md) provided by [IJobEntity](/engine/7000.0/script-reference/unity/entities/ijobentity.md) is an appropriate value to use for this parameter. In an [IJobChunk](/engine/7000.0/script-reference/unity/entities/ijobchunk.md) pass the 'unfilteredChunkIndex' value from IJobChunk.Execute.**** (\[Entity]\(/engine/7000.0/script-reference/unity/entities/entity)): The entity to have the component removed.

### Remarks

At playback, it's not an error if the entity doesn't have component T. Will throw an error if this entity is destroyed before playback, or if T is type Entity or [Prefab](/engine/7000.0/script-reference/unity/entities/prefab.md).

## RemoveComponent\<T>(int, NativeArray\<Entity>)

Records a command to remove component of type T from a NativeArray of entities.

```csharp
public void RemoveComponent<T>(int sortKey, NativeArray<Entity> entities)
```

### Parameters

**** (\[int]\(https\://learn.microsoft.com/dotnet/api/system.int32)): A unique index for each set of commands added to this EntityCommandBuffer across all parallel jobs writing commands to this buffer.

In an [IJobChunk](/engine/7000.0/script-reference/unity/entities/ijobchunk.md) pass the 'unfilteredChunkIndex' value from IJobChunk.Execute.**** (\[NativeArray\<Entity>]\(/engine/7000.0/script-reference/unity/collections/nativearray1)): The NativeArray of entities to have the component removed.

### Remarks

At playback, it's not an error if any entity doesn't have component T. Will throw an error if one of these entities is destroyed before playback, or if T is type Entity or [Prefab](/engine/7000.0/script-reference/unity/entities/prefab.md).

## RemoveComponent(int, Entity, ComponentType)

Records a command to remove a component from an entity.

```csharp
