New world record in VQ3 circle jump

those explanations were way too technical for me. i barely understood any of it.

-128 = basic run speed is 321 not 320
reduced upmove = you can hold +moveup for a very long time, but the game will act like you would hold it for very short time

In case all of this is bullshit(I'm almost sure of that), feel free to correct me

but how are they done? you can say that, with velocity snapping, you can get +25% speed, but without explaining how it works, theres no point.

-128 = basic run speed is 321 not 320

g_speed / 127 * 128 = 320 / 127 * 128 = 322.5 ~ 323

BTW it might be also interesting to realize why that upmove feature doesn't affect cpm rightmove (leftmove) only strafing. I'm attaching a part of cpm code that is responsible for it.

Code: Select all

-128 is not possible on our servers. The value is automatically clipped to -127. Also there is an anti cheat logging file. Same goes for lowMoveup.

Just saying. Don't bother.

And it can be detected in offline demos too

I attached the code I used to calculate this jump. I'm aware it isn't perfect code so don't waste your time telling me so.

Much appreciated.

what does low up move look like, how is it advantageous ...someone post a demo?

you can hold +moveup for as long as you want without losing accel.
