Forums Scripts & Popups Make bot join/leave channel from bot's chat TWITCH

So I want to be able to go to my bot's channel and type:
!join #[insert channel here]

then have the bot command join that channel

Same with leaving
!leave #[insert channel here]

Also OP only would be perfect in this scenario!
Also while on this topic, is there anyway that my bot could respond or only activate the command when only I
type it.

Example:
<Myusername> !leavethischannel
bot proceeds to exit channel

Thanks Again

Something like that.
Use the help files to further understand what it is you need to know to create what you're looking for.
/help if then else
/help on text

something like this would be in your text event you use $chr so it joins their channel #theirname if you use # $+ $nick then it will join #botnametheirname.

That's not what was requested, that would join the channel #nillen in case I were to type it. He requested for it to be "!join nillen" instead, which requires the $2 identifier.
# will not refer to #botname unless the channel it is written in is the same as the botname either, it will simply return the channel name of the channel.
In this case, this would also be wrong. You can join a channel by typing /join nillen, which would make you join #nillen, however, if you have that in your script, and someone would join #nillen, it would turn out as ##nillen, which would be wrong.
