NONAME01150's Zaxis

[Tails_96]

NONAME01150's Zaxis is a lovable module, but I'd like it to work like sidestepping in Tekken, inverting what this module does with doble tap and single tap:

Now, with a single tap, the character walks on the z axis. With a double tap, the character jumps (double up) or couches down (double down)

I want that, with a single tap the character has to jump or couch down, with double tap, the characters has to walk on the z axis. Is there a way ti achieve this? How can I modify this module?
