| ------------------------------------------------------------------------------------------------------ | ----------------------------------- |
| [commandName](/engine/6000.0/script-reference/unityengine/uielements/commandeventbase1/commandname.md) | The command to validate or execute. |

## Methods

| Method                                                                                   | Description                                       |
| ---------------------------------------------------------------------------------------- | ------------------------------------------------- |
| [Init](/engine/6000.0/script-reference/unityengine/uielements/commandeventbase1/init.md) | Resets the event members to their initial values. |

## Static Methods

| Method                                                                                             | Description                                                                                                                                                                                                                                    |

| [GetPooled](/engine/6000.0/script-reference/unityengine/uielements/commandeventbase1/getpooled.md) | Gets an event from the event pool and initializes it with the given values. Use this function instead of creating new events. Events obtained using this method need to be released back to the pool. You can use `Dispose()` to release them. |
