如何做出水下环境效果 - Project1

#==============================================================================
# ■ RGSS3 地图和行走图的波形图 Ver1.00 by 星潟
#------------------------------------------------------------------------------
# 将波形图应用于地图和行走图。
# 实际上是将地图和行走图的视口图像保存为单个图像，然后将波形图应用于该图像。
# 波形图是通过在地图和角色上方显示来实现的。
#
# 默认情况下，可以模拟水下，沙漠和船晃动的效果。
