# State Change Event

The State Change Event allows you to trigger actions based on the state of an object.

<video src="https://cdn.spline.design/_assets/docs/52581247-8251-4a87-887e-ce3cf4e31dce.mp4" controls />

Here are the different properties of a State Change Event.

* **Object** - The object we want to check if the state has changed.
* **Changes to** - If the object gets to this state, the actions will be triggered.

In this example, if `Rectangle` changes to `State 1`, the actions under ‘Then’ will be triggered.

And if `Rectangle` changes back to any other state, the actions under ‘Else’ will be triggered.
