I have often seen the !volume command be used twice in a row to get the intended action of altering the volume by some amount.
UserPerson: !volume
Nightbot: UserPerson -> The current volume is 20
UserPerson: !volume 30
Nightbot: UserPerson -> The volume has been changed to 30
I would like volume to recognize !volume +x and !volume -x as altering the current volume by that amount.
UserPerson: !volume +10
Nightbot: UserPerson -> The volume has been changed to 30
Regex:
^!volume (\+|-)?(100|\d0)$
Thank you for your time.
