Quake 4, like Doom 3, appears to restrict commands preceded by _ and allows one _command per bind, this obviously causes problems when scripting. In patch 1.1 two new commands have been added to enable use of _ commands in a bind, doImpulse and doButton. For example: 

bind l "doButton +_moveup; wait 5; doButton -_moveup" 

bind l "doImpulse _impulse1; wait 10; doImpulse _impulse5"

Vstr is also included and allows a string of commands to be executed, albeit limited in length. NOTE: There are no issues with 'cheat protected' warnings in Quake4 as long as you prefix the vstr string with ua_

Netdemo Record Script
This script sent in by Will "boo" Lyles enables simplified stop / start of online demo recording. Simply press F5 to start the record and F5 again to stop the recording.

Demo Playback Speed Script
This script sent in by Will "boo" Lyles enables you to adjust playkback speed of a demo. After starting the demo press F8 to increase demo speed and F7 to puase the demo or reset demo playback speed to standard.

Zoom with Custom Sensitivity Adjust Script
Adjust as required, this script cycles between 40 / 110 fov and adjusts sensitivity accordingly. NOTE: this script will only work on servers that do not limit g_fov settings (90 to 110)

//Requ!em: Zoom with Custom Sensitivity Adjust
//NOTE: Q4MAX 0.71 users should replace AddChatLine with Echo
bind q "toggle g_fov 40 110; toggle sensitivity 5 15; addchatline 'FOV';addchatline $g_fov"



Map Config Cycle Script
This script can be used to execute specific configs for the standard CTF maps. Simply create a config file for each map that includes your cvars, binds etc.

//Requ!em:Map Config Cycle Script
//NOTE: Q4MAX 0.71 users should replace AddChatLine with Echo
set ua_mapconfig "Q4CTF1.cfg"
bind m "toggle ua_mapconfig Q4CTF1.cfg Q4CTF2.cfg Q4CTF3.cfg Q4CTF4.cfg Q4CTF5.cfg;exec $ua_mapconfig ;addchatline $ua_mapconfig"



LightDetailLevel Cycle Script
This script cycles through values for the r_lightDetailLevel which controls the threshold at which lights are drawn. Any light below this threshold is skipped. This particularly helps with CPU limited systems. Use the script to find the best compromise between FPS and lighting

//Requ!em:LightDetailLevel Cycle Script
//NOTE: Q4MAX 0.71 users should replace AddChatLine with Echo
bind o "toggle r_lightDetailLevel 0 3 5 7 9;addChatLine 'LightDetailLevel';addChatLine $r_lightDetailLevel"
