Someone help me with a very simple script?

[Brinson]

I need a script that when it sees a number in a certain range at a certain place in a line, it executes the roll command. The user needs to be able to set this variable. I know nothing of lua, but from my reading the guides I would think I'd want to use a for...but don't know how to do ranges in for statements in lua.

Maybe something like...

for roll = [1..$target]
send("Roll")
echo("Rolling")
else
break
end

But I know that's not right...can someone help me?

See http://www.youtube.com/watch?v=URbwW41LBcQ and http://lua-users.org/wiki/ForTutorial, along with http://www.youtube.com/view_play_list?p ... xt_from=PL on how to use the equivalent of $target in mudlet

Does that help?

If you want help you to provide more details on the exact MUD output and what you want to do in which cases and which variables you want to set and how you'd like them to be set i.e. automatically (trigger/system variables) or by user interaction (alias/button).

I'm going to watch both videos and start trying to write one, but I'll post here while I do.

My line is: [45] Cmds: help, end, roll, add, rem>

I need if 45 is below the variable set by the user, then the script executed the "roll" command. Eventually, I'd like it to tally how many times it has executed the roll command, and what the highest value of [X] that has been achieved is. But the first and most basic thing is to.

1. Have a way for the user to set the variable.
2. Make it so the mud executed roll when it is less than the variable.

[Heiko]

1. trigger that parses the number in your line: "[45] Cmds: help, end, roll, add, rem>"
trigger pattern: \[(\d+)\] Cmds: .*roll.*>
pattern type regex
script:

Code: Select all

local rMax = maxRolls or 0
local t = target or "no target defined"
local r = tonumber( matches[2] )
if r < rMax then
    send("roll" .. t )
end

2. alias to set the variable maxRolls interactively
alias pattern:^maxRolls (\d+)
script:

Code: Select all

maxRolls = tonumber( matches[2] )
echo("setting variable maxRolls=" .. maxRolls .. " OK\n")

3. alias to see the current value of maxRolls:
alias pattern:^maxRolls show"
script:

Code: Select all

echo("The current value of maxRolls=" .. maxRolls .."\n")

4. triggers or aliases to define your variable "target" that is being used in your roll script

That's it.

[Brinson]

The aliases seem to work fine, but the trigger doesn't.

Not positive I'm entering it right, so I've included a screenshot. In the back is the pattern I'm trying to match.

It seems to me the trigger isn't matching. It just isn't doing anything.

[Heiko]

remove the space from the beginning of your pattern

Also enable anti-aliasing in the main display tab of settings to make fonts look nicer.

[Brinson]

Okay, so...I changed it up a bit.

Code: Select all

local rMax = maxRolls or 0
local r = tonumber( matches[2] )
rHigh = rHigh or 0

if r > rHigh then
rHigh = r
end

if r < rMax then
rTot = rTot + 1 or 0
    send("roll")
	 echo("You have rolled ".. rTot .." times with a highest roll of "..rHigh..",")
end

It works fine...I had it working...but then I restarted my client, and now it won't work at all...any idea why?

I'm guessing something to do with variables?

[Brinson]

No one have any idea why the script would stop working upon restart of the client?
