Alright, I have bits and pieces from certain people that could help here, but I'm lost on the rest.

Here's what I want:

A script that randomly changes the variable %mood to one of these settings: Happy, Sad, Angry

After that I need it to pull and do a $read from a text file, based on the current value of %mood.

If %mood = happy then pull a $read from happy.txt
If %mood = sad then pull a $read from sad.txt
If %mood = angry then pull a $read from angry.txt

but it needs to be randomized.

[script]
n0=alias -l brandtime {
n1= var %lowtime = 100 | ; quickest duration between messages (in seconds)
n2= var %hightime = 500 | ; longest duration between messages (in seconds)
n3= return $rand(%lowtime,%hightime)
n4=}
n5=alias brandmsg {
n6= var %rline = $read(brand.txt)
n7= if (/me* iswm %rline) /describe $1 $gettok(%rline,2-,32)
n8= else /msg $1 %rline
n9= .timer [ $+ [ $1 ] ] 1 $brandtime brandmsg $1-
n10=}

The above script does a $read from the text named brand based on the random times caused by the settings of the 2 numbers: 100 & 500
I had hoped this could be added with the above %mood variable scripting, so that based on the 2 numbers the mood will randomly shift to another of the options available.
I'd like them both combined, so that the mood will shift randomly based on its 2 numbers, and the bot will speak, or do an action, based on a different set of 2 numbers. So I can customize how often they both happen.

Finally, after thats finished I wanted some text triggers put in, to cause a mood shift based on what is said to the bot.
Something like

If someone says: I love you, [botname]. Then the %mood variable will be changed to happy and the bot will then speak in main: I love you too $nick. (So that she will reply back to whoever spoke the words.

Another type of text triggering I'm interested in is using keywords, like this.

If the words I and hate and [botname] all appear in one line of text then the variable %mood should be changed to angry and the bot will do this as an action /me storms off to be alone.

another example is to set up the same as above, but using if and or, like this

If hate and [botname] or sucks and [botname] appear then the %mood changes to angry and the bot says "Well I hate you!"

I know this is a big job, and I hope someone is capable enough to figure how this entire thing would look.

this is not tested and prob could be made alot smaller

Here's a condensed version of Glue's script

Russell I copy pasted your script in exactly, and only changed the 3 times to shorter increments, the only thing it does is say randmood in the console.

scractch all the stuff you have put up here, I may have a simpler way to do this...

First it needs the random timer, for speaking

that would be this I think

alias -l brandtime {
var %lowtime = 100 | ; quickest duration between messages (in seconds)
var %hightime = 500 | ; longest duration between messages (in seconds)
return $rand(%lowtime,%hightime)
}

then just do the roll random number out of the number of moods
and have it set to do if 1 then read happy
if 2 then read sad

nd display 1 line from it at random intervals in the room

Did you have the client that you put the script on, disconnect from the network, then reconnect? If not, then the ON CONNECT event won't have triggered
