I want to customize the sar ihud but don’t know how and can’t find helpful resources. A list of the ihud commands would be appreciated.

Go in the discord and ask in technical-help.

I would always refer to this. If some commands wont work: be sure you have the current version of sar. https://nekz.me/SourceAutoRecord/doc/cvars.html use Ctr. + F to find the ihud settings

This is extremely out of date please do not link this anymore. Use this https://github.com/p2sr/SourceAutoRecord/blob/master/doc/cvars.md

That link shows the list of commands, but instructions with example commands would be helpful, and I did not find much when I was trying to do this a few days ago.

Here are some commands I came up with to customize my ihud:

sar_ihud 1
sar_ihud_y 800
sar_ihud_x 375
sar_ihud_modify forward   y=0 x=4 text=^
sar_ihud_modify back      y=1 x=4 text=v
sar_ihud_modify moveleft  y=3 x=4 text=<-
sar_ihud_modify moveright y=3 x=5 text=->
sar_ihud_modify jump      y=0 x=1 width=2
sar_ihud_modify duck      y=1 x=2
sar_ihud_modify use       y=0 x=0
sar_ihud_modify attack    y=0 x=6
sar_ihud_modify attack2   y=0 x=7
sar_ihud_modify angles    y=1 x=6 enabled=1 font=-5 width=2 height=2

Hope this helps.
