Filled region vs clicking actor

[Clokio]

Is there a reason of performance to have a filled region. Can a transparent actor would do the same?

Thanks

The filled region actor can be any size, as set by the user, without needing an actual image. If you replaced every filled region with a custom image, you could be dealing with a very large game size, and since the filled region is already invisible it is more convenient.
