/*:
 * @plugindesc v1.0 Change sprites when dashing.
 * @author DreamX
 * @help
 * ============================================================================
 * How To Use
 * ============================================================================
 Actors will change their sprite while dashing if an image file with the same 
 name as their character image file exists, but with _Run added to it. 
 For example, if the actor's normal sprite is using the Actor1.png image file, 
 Actor1_Run.png must exist in the same folder. The character index will be the 
 same. 
 
 By default, if a run sprite could not be found, then the sprite for an actor is 
 simply not changed.
 
 Use <NoRunSprite:1> for an actor to disable changing their image on dash.
 * ============================================================================
 * Compatibility
 * ============================================================================
 This plugin is compatible with Shaz's more character frames. Instead of adding
 _Run to the very end, you'll add it just before the part about the character 
 frames. For example, the run equivalent of an image named $Character [8 8 8 8] 
 becomes $Character_Run [8 8 8 8]
 * ============================================================================
 * Known Issues
 * ============================================================================
 The first time while dashing, there may be a momentary flash of the sprite 
 when the image changes. It's more noticeable if you're using Shaz's More 
 Character Frames.
 * ============================================================================
 * Terms Of Use
 * ============================================================================
 Free to use and modify for commercial and noncommercial games, with credit.
