You can find these prefabs in the `/Assets/ENGAGE_CreatorSDK/Prefabs/Tools` folder. The functionality of these prefabs is described in the table below. {% hint style="warning" %} Duplicate an asset before you use it, and then move the duplicate to the appropriate dependency folder. Future updates may move or remove example prefabs in the Tools folder. {% endhint %} {% hint style="info" %} Update your SDK regularly to get the latest versions and any added prefabs. For more information, see [Checking for SDK updates](/developer/setting-up-the-engage-sdk/checking-for-sdk-updates.md). {% endhint %} | Prefab | Description | | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | /SitPrefabs/DefaultSitTrigger | Add to seat geometry to enable an avatar to sit.

Cornhole Game

| A fully interactive game object that's synchronized between all users in a Session. | | ENGAGE\_SitTrigger |

Deprecated
Use the /SitPrefabs/DefaultSitTrigger prefab in locations, and the IFX\_SitTriggerSimple prefab for IFX.

Use this version if you design the IFX to be scaled. | | IFXNetworkStates\_GenericEventsExample | If you want to create an IFX that responds to network states, you can use this prefab as the root object.
