 #### Handle actions
 
-The `channel` is also the abstraction used to handle an action when it's triggered by another smart item. For example lets go back to the `Door` smart item, it has two actions: `open` and `close`. Those actions can be trigger by any smart item (could be the `Door` instance itself or another smart item, like a Lever that when pulled opens a Door).

-This will handle an action when it's broadcasted through a channel using `channel.sendActions(...)` (see [section above](#send-actions)). Since actions that are broadcasted that way will not only reach other smart items in the scene for the current user, but also other users in the scene, the callback that we pass to `channel.handleActions` receives a `sender` that can be used to know if that actions is coming from the same user or a different one. When we open a door we don't care about who opened it, because we want everybody else on the scene to see that the door just opened. But there are other actions that we want to keep just for the player who triggered it, for example, let's say we create an smart item that can be equipped, we want to make sure only the user who triggered that action actually gets the item equipped, so we can do so like this:
