Overview
The Progress Bar control type lets you visually represent a percentage value. It is also useful for health bars. Valid values for a Progress Bar are between 0 and 1. 0 meaning an "empty" bar, and 1 meaning a "full" bar.

NOTE:
It is recommended that Progress Bars not be set to Pixel Perfect or Auto Resize, or else should have their anchor set to a left-aligned method.
Interactivity
The ProgressBar control does not receive any user input.

You can set and retrieve the current value of the control through the Value property. Valid values are in the range of 0-1.
States

There is technically only one "state" for the Progress Bar control. However, to define its appearance, you must fill in the following "states":
 
Filled
The appearance of the "filled" portion of the bar.
Empty
The appearance of the "empty" (yet-to-be-filled) portion of the bar.

NOTE: This state is optional if you only want the "filled" portion to be visible (such as is often the case with health bars).
disabled
State when the control is disabled.
Disabled
This state indicates that the button is disabled and will not receive input.
