I thought about the path movement, but its path is fixed and it's difficult to make curves following the line accurately...
And what I'm making is a Mario level editor so I hope the guiding line can be seperated into 32x32 tiles that when joined together the platform just follows it

And I'm also making an "Engine" (level making template) for other Fusion users based on that editor's code, so the ideal effect could be just let the user draw a line in the built-in image editor and the platform follows it <-I don't think this is possible
