You can add me on steam, I've been playing spy for nearly 6 years now and I would be happy to help you out :)

I don't play spy but this would be neat to know just because.

However for your particular need I am 99 percent sure that knowing the exact number won't help as much as just getting a feel for it.

Yea, Its definitely a 'feel' thing.. but numbers might help me learn a bit, especially if the mechanic isnt intuitive. I feel like your acceleration from moving is probably just constant till you hit max speed, but this might actually not be the case. It happens very quickly, so its hard to tell.

you mean acceleration? i don't know but you can use cl_showpos 1

Acceleration to max speed is pretty much instant.

Yes I'm using this. But its very hard to tell properly. Also its in the corner of the hud and I dont believe you can move it.. so its not the most helpful command for using In game.

bro its not like counterstrike where u have to counterstrafe to shoot. u dont really need to know acceleration for tf2

if you really want to find out just open up OBS and turn on showpos

Its for improv stabs, where you need to hit max speed before you jump off of a crate or w/e

I have that on already :P It doesnt help much because its not centered and its tiny as hell.

again, it's not really that important. also, i'm not sure what your whole deal with "spy needing to hit max speed" entails. if you play spy, you should know that any sort of funky stabs are always going to be inconsistent and are a bad thing to practice in official play.

Dude the entire point of learning is to make it more consistent. Getting a full jump or a small jump can be the difference between a successful stab from overhead, and a failstab. I just figured if there was a place to ask this would probably be my best bet.

use null movement script. your problem is probably that you are hitting S and W at the same time when your fingers try to make the swap to fully hitting S.

heres a diagram of whats probably happening

you going up the stairs with someone chasing you:
- W -
- - -

you the moment you realize you can stair stab this guy:
- W -
- S -
at this point your character has stopped moving completely meaning your moment wont transfer on your next keypress, and instead you have to start from zero velocity.

you fully committed to the backpedal:
- - -
- S -
now you're ramping up from 0 velocity to max velocity instead of going the same velocity you'd be going if you counter strafed correctly

null movement script should stop you from halting your own movement

I have this already. The problem is I'm not moving far enough to hit the max velocity. I just wanted to know how far I have to move, or how fast it ramps to max velocity.

I think it takes around 9 ticks to reach max velocity. To test it, you can record a demo of yourself moving straight in your desired direction, then watch the demo frame by frame from the start of your movement until you hit max velocity and count how many frames did it take.

I still don't know how this information will help you in game, you just need to develop consistent timing by practicing it.

i dont recommend null movement script. i dont know what stops ppl from learning to press keys manually. all u have to do is practice:

press A > let go of A > press S

i would agree with you, but muscle memory is one powerful son of a bitch. i couldn't go without a null movement script at this point.

no. you don't understand what i'm saying. trickstabs and what not will always be inconsistent as a mechanic because they're more of an engine glitch than anything. besides, most competitive players won't fall for them anyway.
