Trigger filter, multiline, and deleteLine() question

[RoninZero]

I have a rather annoying problem and I'm hoping some of the more experienced Mudlet users can assist me with.

My mud uses a special trigger string to make creating client based triggers easier.

For example, when there is a change in my vitals, my mud sends:
xxxxx_prompt 150 200 300 300 400 400

Which is in the following format "HP maxHP MP maxMP MV maxMV". There are a fair amount of these xxxxx_.* triggers in the game.
They all follow the same format of xxxxx_ followed by something, so instead of creating a trigger for each i decided it would be more efficient to use a trigger filter as such...
^xxxxx_ (perl regex)

then in that group I have added a trigger
prompt (\d+) (\d+) (\d+) (\d+) (\d+) (\d+).*$ (perl regex)

Code: Select all

echo(string.format("HP: %d/%d", matches[2], matches[3])
deleteLine()

This work beautifully, except *sometimes* the xxxxx_prompt is followed by an extra line which is not being deleted, thus causing excessive scrolling.
I've tried multi-line and fire length both inside and outside of the filter group, but can't see to remove the extra line if it present.

How do I delete the extra line if it's there?

I've tried multi-line and fire length both inside and outside of the filter group.

One way would be to use a tempLineTrigger() that'll go off on the next line only, check if it is blank and then delete it. Try that out, let me know if you get stuck!

Thanx Vadi!

It took some messing around but I finally got it working.....
Although it feels kinda wonky. (Don't worry, this will eventually be converted to events just trying to get used to Lua and Mudlet)

Here is the result:

Code: [show] | [select all] lua

cur_hp = matches[2]
max_hp = matches[3]
cur_mana = matches[4]
max_mana = matches[5]
cur_move = matches[6]
max_move = matches[7]

clearWindow("My floating window")

echo("My floating window", string.format("\n<-- HP: %d/%d  MP: %d/%d  MV: %d/%d -->", cur_hp, max_hp, cur_mana, max_mana, cur_move, max_move))

-- Will fire 3 times with the next line, trying to remove blank lines
tempLineTrigger(1, 3, [[if line == "" then deleteLine() end]])

-- delete the initial trigger line actual 
deleteLine()
