Okay, I didn't realize that the scout part would just not work, it's quite connected with TF2Turbo, the way you just need to hold space and when in air, you can literally just change the direction of the double bhop. So unless you almost entirely replicate TF2Turbo's feature where you can just hold space to bhop, this is a lost cause
The crouch bhop doesn't work either. If you hold crouch and then try to jump, I think you'll get the clue.
