# Proximity

Proximity is the nearness in space between objects. The **Proximity** condition checks if (at least) two objects are near one from each other.

The condition includes the following parameters:

* **Mode:** if you select `ENTER`, it means objects have to be **close from one another** at least at the specified distance (or below).\
  If you select `EXIT`, it means objects need to be far from each other, at a distance above than the distance set.
* **Max distance:** distance, in meters, between objects for the condition to be valid. Objects should be either at this distance or below to validate the`ENTER` or be above to validate `EXIT`.

*Note that the condition uses the Proximity colliders of the given IOs , the distance is calculated from the center of each collider but you can choose to calculate from the edges.*

* **Objects in proximity:** objects ([IO](/adding-interactivity/interactive-objects.md)) that need to be in proximity (at least two). You can add more than two objects, then if `Require All` is checked, all the specified objects in this list are required to validate the condition. If `Require All` is not checked, only one combination required for validating the condition.

**Minimum duration required:** check details [here](/adding-interactivity/interactions/conditions/duration-parameter.md).
