                        Dashing Stamina v1.2
                            by wltr3565
================================================================================
One of my "assignments" as my team's scripter. He needs a script for limiting
dash. So I made this one.
================================================================================
Features:
- Configureable dashing limit.
- Easy to use, maybe.
- Animative gauge HUD.
- Adjustable "tired" period.
- Available for using image or the normal gauge!
================================================================================
How it will work:
The stamina will be consumed as the player dashes, and recovers as the player
stops dashing.
================================================================================
How to Use:
Configure the module below. The HUD_SWITCH sets the switch for turning the HUD
on or off. And to change the stamina limit, use this in the script command
event:
  $game_system.max_stamina = n
n represents the new max stamina.
================================================================================
Install:
Insert this above main.
================================================================================
Terms of Use:
Credit me, wltr3565, or not is up to you. Just don't claim that this is made by
you, and crediting me will be nice.
================================================================================
Thanks:
Kuro Creator: My boss.
