Hello mates I'm having a really dumb trouble I never had this thing... before ,I will explain:
I just downaded a Decal converter to convert spray paint everyting is ok i convert put in cstrike directory then start game spray and i see my spray paint ,but when I restart CS my spray paint is gone !!?(I see a default spraypaint) and the same thing with config file I added a:
balias +bhop "alias _special jump;jump"
alias -bhop "alias _special"
alias jump "+jump;wait;-jump;wait;special"
bind "MOUSE3" "+bhop"
I save, start game and the bunny hop works and when i turn off cs and turn on and it's gone, i'm open config and the cript i added : alias +bhop "alias _special jump;jump"
alias -bhop "alias _special"
alias jump "+jump;wait;-jump;wait;special"
bind "MOUSE3" "+bhop"
is gone !!
it's like the files restarts to default did someone had this trouble and knows how to fix it ? I would be really happy if someone would help me
i tryed to download other cs and it's the same problem

If you want some special script for your counter-strike, add it to userconfig.cfg: JMember's Blog: Specific configurations
And about the spraypaint, right click on the tempdecal.wad (cs 1.6) and go to properties. Set the file to "read - only"
