# Player body trigger

A player body trigger is triggered when a player walks into it. You could use a player body trigger to play a sound or activate a video screen when a user enters an area.

A player body trigger is represented in the Experience Editor environment by a transparent cube with a grid material. However, the trigger is invisible when a user plays your experience.

The only effect options that you can set for a player body trigger are those described in [Effect options](/engage/experience-editor/working-with-objects/effect-options.md#common-effect-options) and [Triggers](/engage/experience-editor/working-with-objects/triggers.md#trigger-effect-options).

{% hint style="info" %}
To test your triggers while in the Experience Editor, select play (<img src="/files/CwI7WowaHQLoRuHgRPDU" alt="" data-size="line">) on the playback controls, and then minimize the editor panel. You can then move through the player body trigger.
