# 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.
