Stepper

==============

A stepper control, like those found in iOS. It's basically two buttons side by side, and can step its numeric value up and down.

Overview

The Stepper Control creates an increment / decrement style control with + and - buttons which alter the controls value.

It exposes a value property where you can also set a min and maximum number for that value when changed through the control. Additionally you can also specify the "step" which denotes how much the control increments / decrements with each press, as well as an option to loop the value around from top to bottom, etc.

Like the Segmented Control, you can also specify a Separator image attached to a GO to place between the buttons.

NOTE You can only have two child buttons attached to the Stepper, one each for the + and - actions. Adding more will generate an error.

Properties

The properties of the Stepper Control control are as follows:

Property	Description
Value	The current value of the Stepper control
Minimum	The minimum value for the Stepper
Maximum	The maximum value for the Stepper
Step	The number to increment / decrement the control with when the buttons are clicked
Wrap	Does the value of the stepper wrap around when the max/min is reached
Separator	A graphic based UI GO, which will serve as the image that separates each button. *Note, you should disable the GO used for the separator or use a prefab to avoid dirtying the scene.
On Value Changed (event)	The Event fired when the handle within the value of the control is changed

Usage

Simply add the default Stepper to the scene using "UI / Extensions / Stepper" in the Editor "GameObject" menu.

It is also available as a Game Component menu in "UI / Extensions / Stepper". However, you will need to manually add the two child selectable controls (e.g. A UI Button or other control implementing the "Selectable" interface).
