Hello! How do I get objects to scale with Slline?

[qzm26999]

I modified the script, originally I used the multiplier method and changed to use the added method.
我又修改的腳本，原本我是使用乘數的方法，又改為使用增加的方法。

This method better controls the size of the object.
此方式更好控制物件的大小。

And change the flash time to turn flash.
並且將閃時間更改為輪流閃。

I have successfully achieved the effect I want, but is there a better way?
