what is the way in rn-lf

[no one]

First, creat a new frame in all of your char if this is for a mod.
Second, In all of those frame note an bdy with somthing like y: 50000.
Next, In every frame of the barrier note an itr/kind: 8 with the same y values and a dvx which lead to the disappear frame.

That's all. Happy coding^_^
