# ModifyPlayerData

The following script can be added to PlayerStats ( or any gameObject in a scene) To provide a way to **configure a UI Button in the Inspector Panel** to modify GameData Score or Health.  It's necessary to use a helper script like this since GameData is a singleton and therefore is not available as a gameObject in any scene other than BeginScene, to configure calling public methods to change GameData values.

**PlayerStats Prefab:  UpdateText:**  \
**Note:**  I have added a new UI-Text field to PlayerStats Prefab to display text to indicate when data's been updated.
