# Interactive Trigger Area

Within Grid Studio, it is possible to define an area in 3D space for interactive purposes.

Some of the things that Grid Studio can do once there is this defined area include:

* if an object has entered the area
* if an object has left the area
* when the defined area is empty
* if objects inside this defined area is moving

All of this is primarily enabled by the Area object. For details about the object and all of this properties please refer to this page.

### Prerequisite

* Area
* object of any kind or a folder of objects
