Is there a script

[ZeeDic]

that make it so when you fire you weapon the view model turn off and when you switch weapon the viewmodel return?

alias "viewmodeloff" "r_drawviewmodel 0; +attack; wait 66; -attack"
alias "slot1v" "slot1; r_drawviewmodel 1"
alias "slot2v" "slot2; r_drawviewmodel 1"
alias "slot3v" "slot3; r_drawviewmodel 1"

bind MOUSE1 "viewmodeloff"
bind 1 "slot1v"
bind 2 "slot2v"
bind 3 "slot3v"

There you go :) just put that into your autoexec.cfg and you should be good.
