I want my Alt button to fire and change sensitivity temporarily until the key is released.

1) press Alt
2) fire + change in sensitivity, e.g. 0.8
3) release Alt
4) fire stops + change back to original sensitivity, e.g. 1

Can it be done? No?

EDIT: I think I got it

alias +l33tacc "sensitivity .89"
alias -l33tacc "sensitivity 1.0753"
bind ALT "+attack; +l33tacc"

Can I make my mouse accel curve in quake live look like this:

?

How to calculate cg_projectilenudge if I also use cl_timenudge?

[ping] + [negative timenudge] = [projectilenudge?]

or in numbers:

44 + (-8) = 36

quote from openarena wiki:

Note that it is possible to use cl_timenudge together with cg_projectilenudge, but calculating to which values you should set them together is not intuitive and therefor not very practical, and aiming and firing hitscan weapons becomes more difficult too because you have to take the cl_timenudge value into account and lead (or even trail) your targets.

I have discovered that cg_trueLightning = 80/(80+ping) for pings lower than 80 works better than "officially" recommended "cg_trueLightning = 1"

conf file with vstr stuff: http://www.mediafire.com/?4nqahj7z495v06p

Don't forget that you need "exec truel.cfg" and the following binds in your autoexec.cfg:
bind UPARROW "vstr tlfw"
bind DOWNARROW "vstr tlre"
bind LEFTARROW "vstr tlle"
bind RIGHTARROW "vstr tlri"

For this to work best I recommend also cg_smoothClients = 0, cl_timenudge < 0 (I use "-8" because 1000/125fps = 8ms to render each frame) and cg_projectilenudge = 0 (reason explained here: http://openarena.wikia.com/wiki/Tweak)

I've tested this across the ping range from 16 to 49. It takes a little time to get used to, but somehow this all makes more sense to me than using value "1".


EDIT: I NO LONGER BELIEVE IN THIS. With truelightning below .8 it becomes very difficult to track an opponent that can strafe well.

Can I use "0.5" for m_filter or is it strictly "from 1...33? I think that i can feel a difference between m_filter 0 and m_filter 0.5, but this could be a placebo.

Also Quake Live console guide says that it's either 1 or 0
