|
|
|
|
Handles the visibility and updating of player pet happiness.
|
|
|
|
## Widget
|
|
|
|
HappinessIndicator - A `Texture` used to display the current happiness level.
|
|
The element works by changing the texture's vertex color.
|
|
|

A default texture will be applied if the widget is a Texture and doesn't have a texture or a color set.
|
|
|
|
