影子脚本如何不卡

Coder7447

我用了影子生成脚本   [pre lang="ruby"]#使用方法：不透明的物体在光源旁边会产生一个阴影。

#所以，在光源的事件里面（例如火），请在第一页加上一个注释“s”（请不要带引号）

#然后将此脚本命名为“人物阴影”插入到main上方即可。


#==============================================================================

# ■ 阴影精灵 (渐变精灵 )

# 以 Genzai Kawakami的阴影脚本为基础,
#  Rataime为其重写和更新，
#  Boushy 为其添加附属功能

#  精灵使者汉化

在地图上创建30个光源 ，之后即使主角离开光源 即使影子不存在 也会因为影子的刷新(虽然看不见 但仍然存在刷新）而使FPS下降，
请问如何解决

即 透明度==0的时候  把它释放，该如何写？   忘赐教

那没有办法解决了吗
