Hi,

Can anyone point me to a resource or offer some tips on getting values say from a trigger passed into a lua script? I feel I'm missing something obvious so, sorry if that's the case.

If I have trigger that looks like
"^Contains the spells: (*)"
in the command line. Can I pass the value of the asterisk directly into a variable/table within a lua script? Or is the solution to have the trigger fire and capture the value into a #VA variable and then execute a lua based script when I've captured all of my #VA variables?

If the latter, or in either case for that matter :) could I get an example?

I've read the tutorial and I have a good book on Lua, just need some help working out how to pass data back and forth from lua scripts to the primary mud window.

Yeah, I need to finish that part of the tutorial. Basically, read this, that lets you access all of CMUD's normal functions. In this case you need the zs.param() function, or perhaps zs.params() for an alias.

Slick. I've bookmarked the page.

I'll have to play with it to figure out how things work, but thanks for giving me the next breadcrumb. (or a bit more)

BTW.. Kudos on the tutorial. It's good reading and for our purposes (mud scripting, is very concise.) I picked up Programming Lua and while I'm less than 100 pages into it, everything you wrote agrees. (minus about 80 pages of who/what/when/where/why which when scripting, is a great thing.)

I'm too aware of how negative feedback stops me from offering more to my users, I'm in IT for a quote, living, unquote. Doc's are the least appealing part.

So thanks. :)

Ok, I'm now able to get lua code to function in an alias, but when I attempt a trigger with the pattern "^Contains the spells: (*)" it will not fire. The same trigger with zscript selected will fire so I believe I have the pattern correct, but when I select Lua as sthe scripting language it does not fire at all.

I even tried trimming it back to "^Contains the spells:" but still get nothing.

Is there a different syntax I need to use for trigger patterns if the scripting language is Lua?

Now it's working.

I had default script language set to zscript. I had the script language for that trigger set to Lua though, odd that it didn't work. Once I changed the default language to Lua, deleted the old trigger and created new it began working.
