Description

This creates a scrolling GUI keyboard.

Usage

Provides a very simple on screen gui virtual keyboard for inputting text. Add to any GameObject, assign the textures and GUISkin. All the output is stored in the "character" variable as a string, which can be accessed from other scripts, the "reset" button erases the content of said variable.
