How would I match these things to set variables?

My prompt looks like this (the whole line):

3670h, 2460m, 2820e, 10p, 15882en, 10600w elrx-

But I'm most concerned with the final part of it that says
elrx-

Now this part shows me various balances and stats. For example e tells me about me equilibrium, l tells me if my left arm is on balance and r tells me if my right arm is on balance.

Also, that last part can have more things at the end of it, depending on things I do, like eating a "kafe bean" might turn this into

elrxk-

Now to the question. I want to keep track of when the e,l,r and x parts are gone. Any of them can be gone individually at any time. When it does I want to set a variable to 0. And then I want to set it to 1 when it comes back.

[to illustrate what I mean, let's say I equilibrium is gone, it would be lrx- until it comes back and then it is elrx again.]

How would I go about doing this?

I am a bit short on time, and rather not spend the time chewing your entire problem out when a few weeks ago, I tackled the same problem for someone with a similar issue.

Have a look at this thread: http://www.gammon.com.au/forum/?id=10619&page=999

Alternatively, look around for the word 'prompt' on these forums. This issue comes past so often that it really is only a matter of applying the answers to fit your specific situation.

Alright! Thanks for that. I used that knowledge and then found out I actually had a nice trigger already set up in my system that allows me to take advantage of that.

You can consider this problem solved, but do you think this can be simplified any?

Not really without knowing the bigger context and such.

The only 'simplification' I can offer is to use booleans rather than integers for your flags. E.g. offbalance = true or nsent = false, and likewise checking for those values.

Truth and false (on/off, yes/no, etc) are ment for this kind of thing, and it makes your code easier to read. Likewise, because an if-statement is basically checking for the 'truth' in an expression, you can simply say if nsent then.

Well here:


if (string.find("%7", "e")) and 
   (string.find("%7", "l")) and 
   (string.find("%7", "x")) and 
   (string.find("%7", "r"))
then 
offbalanc = false -- If all these match, you're not off balance.

Does the server randomize the order of the letters? If not, why not just test:


if "%7" == "elxr" then
  offbalanc = false

And Worstje is right:


if nsent==true then

... is just wordy.

Make it:


if nsent then
