Hello, do you remember the propeller
pipe? Well, that's what i call it.
Because i don't know whats the real name
of that pipe. But well.
My question is: How i make a propeller pipe? I I tried many ways, but i don't have results.

Do you mean a Pipe Cannon? If so, you should be able to place it in your level using Actor ID 189. Check out 6-6 for examples of using the sprite.
