Help with bunnyhopping

Referring to code from this bunnyhopping system, I want to modify it in a way so that as players bunnyhop, they gather up speed.

The problem is, with the system I’m referring to, air strafing plays an important part in the speed a player can gather. Meaning it’s heavily dependant on mouse/camera movement, which I don’t want affecting the player’s speed at all.

I’m not exactly sure what part of the code affects the player velocity through camera movement.

take a look at this

Double Jumping.

I don’t think you quite understand what I’m trying to achieve.

To clarify, I want to create a custom movement system that allows the player to gather up speed by side strafing while in the air. The code I’m referring to relies a lot on the player’s camera movement as (I’m assuming), it was originally based on the quake or source engine movement code.
