Battle Background Scroll

Battle Background Scroll
Version 1.00
SumRndmDde

This plugin allows the backgrounds within battles to scroll in both the 
X and Y directions during a battle.

==============================================================================
Troop Notetags
==============================================================================

In order to set scrolling to a troop's battle backgrounds, you can use
the following notetags within the Troop's NAME section:




Using these, you can set both X and Y Speeds to the Backgrounds 1 and 2
of the battle.

For example:

Bat*2   

==============================================================================
Plugin Commands
==============================================================================

You can also use the following Plugin Command to change the speed of
the battle backgrounds in the middle of the background:

SetBattleBack1ScrollSpeed [xspeed] [yspeed]
SetBattleBack2ScrollSpeed [xspeed] [yspeed]

These Plugin Commands are pretty simple. You can use them to manipulate
the Battle Backgrounds 1 and 2 respectively. Simply set "xspeed" and
"yspeed" to the X and Y Speeds you wish to use.

For example:

SetBattleBack1ScrollSpeed 3 6
SetBattleBack2ScrollSpeed 0 -10
