プレイヤーが立っている地形タグ（またはリージョン）に応じて、戦闘が開始されたときに表示される戦闘背景を指定するプラグイン – Galv_TerrainBattlebacks.js

Galv's Terrain Battlebacks
----------------------------------------------------------------------------
This plugin allows you to specify which battlebacks appear when a battle
is started depending on what terrain tag the player is standing on.

By default, RPG Maker MV automatically selects battlebacks on the overworld
map depending on the tile you are on. This plugin keeps that functionality
but settings you choose will take priority over that.
In addition to the plugin settings, you can also use map notes to specify
what terrain and region battlebacks are for individual maps.

MAP NOTES

<rbacks x:battleback1,battleback2> x = region id to overwrite

<tbacks x:battleback1,battleback2> x = terrain tag to overwrite


NOTE: The chosen battleback will be determined by numerous factors in your
game. Here's a list of the priority it uses to determine which battleback
is used at the time.


PRIORTY OF BATTLEBACK SELECTION
1. Map setting 'Specify Battle Back'
2. Event command 'Change Battle Back'
3. Region id map notes
4. Region id plugin settings
5. Terrain tag map notes ~~
6. Terrain tag plugin settings ~~
7. Default RPG Maker auto battle back selection based on tile ~~
8. No battle backs at all.

~~ Note: RPG Maker seems to assign terrain tags to A tiles, even though you
set them to 0 in the database. Be aware that this means that even though
you set them to 0, they might still be a different number and be looking at
your terrain tag settings to find the battlebacks relating to whatever
that tag number is.
