Pausing script for llListen input...

I need to pause my script while I wait for input from one of my objects buttons.

Should I do this using a do-while loop, and as long as the listen even hasn't received one of the two inputs it accepts, keep waiting? Or is there a better way to do this?

If you use a loop you'll never recieve the listen event as the current block (the do while) will keep on running, blocking the listen event being fired. Depending on the situation, just doing nothing, and executing the rest of the code in the listen event may be the way to go.

LSL is an event driven language.

What this means is that a script is always sitting there doing nothing until an event happens.

When something happens, the event-handler for that thing is called, it runs and then the script goes back to doing nothing.

So, when you compile a script, something happens right away, the "state_entry" event handler is called to handle that, and you want that to finish and the script to get back to busily doing nothing so that it will be ready to process the text it hears in its listen event handler.

except when it's handling an event

I hope this un-confuses you more than it confuses you.

Ah, but on re-reading your post, it seems like you want your script to not handle other events until it hears a certian something. What you want is a new state!

Something like:

CODE

default {
 state_entry {
  llDialog(...);
 }
 listen(...)
 {
  if (something)
  {
    state active;
  }
 }
}

state active
{
/* do stuff */
}

Yeah, the script essentially needs to freeze until it gets input; I'll play around with your snippet and see what I come up with. I can't believe how much I accomplished in the past 24 hours with everyone's help here.

Phht... I'm a dunce. I just can't get a grasp of the concept, and the script just keeps giving me syntax errors in that spot.

I've changed my original approach to listen for a linked mesasge from another prim in the group, could that be it?

Nope , Wednesday's approach is very sound.

Break up your code into different states.
I'm at work and can't write example code atm....

But the concept is pretty simple when you get into it.. Imagine a door in SL -- a door could easily have 2 states, Open and Close...


Your script set your door as Open, wait for input, the change state to Closed.

Your closed state would do the same. set the door closed and wait for input before changing state to Open.

Thats the simplist way I can think of to explain it....

Siggy.
