# Use

Use Triggers apply to either the entire object or to its Hitboxes, which allow precise locations and sizes to be targeted by the End User.

* To make an object usable only while it is grabbed, set the Use Category to Virtual Object.
* The HitBox Use Category can only be used if the object has Hitboxes on it.
