如何实现远景图滚动 - Project1

# ▼▲▼ XRXS34. パノラマスクロール ▼▲▼
# by ぷのくー
#——————————————————————————————————————
# 这是一个非常简单的脚本，只要自定义自动滚动的地图编号和绝对不滚动的地图编号
# 即可实现对远景的操作。

#==============================================================================
# 初始化的一些常量
#==============================================================================
class Game_Map
# 远景横向飘移速度速度
PANORAMA_SX = 0
# 远景纵向飘移速度速度
PANORAMA_SY = 10
# 自动滚动远景的地图编号(编号为1、4、7、5的地图远景会自动移动)
AUTO_SCROLL_PANORAMA_IDS = [2,4,7,5]
end
class Spriteset_Map
# 锁定远景的地图编号(编号为2、8、10的地图远景会锁定)
SCROLL_FREEZE_PANORAMA_IDS = [1,8,10]
#——说明：如果自动滚动和锁定都包括了某张地图，则该地图不滚动。
#——如果自动滚动和锁定都没有包括某图，则还是会使用默认效果。
