TACtical movement is a mod that adds a lot of movement features into minecraft. Currently It adds the following (You dont NEED TACZ or VPB for this to run and work, you only need PlayerAnimator) (you can use either tacz or vpb, or both, or none)
-Proning Makes your hitbox smaller and essentially sets you to crawling, the animation is specifically setup to fit well with gun mods such as TACZ or VPB
-Leaning Allows you to quickly peak a corner, angles your first person camera and displays a third person animation you can also shoot around the corner while leaning, your bullets will still hit where you are aiming. -Sliding Does nothing to your hitbox but gives you a short boost of speed, also has an animation and a cooldown.
-3rd person animations for reloading and gun handling
