Help with my first simple trigger?

[dss]

With regards to targeting:

I have created the following alias:

Code: Select all

Pattern: ^af (\w+)$
Script: target = matches[2]

And I have created this trigger:

Code: Select all

Perl Regex: ^(.+) leaves (\w+).$

Script: if matches[2]:find(target) then
send(matches[3])
end

I enter a room with a tiny sand fly, I type "af The tiny sand fly" (and have alternately tried "af fly" "af sand fly" and "af tiny sand fly") and the mud reports back with "What?"

I get this error:

Code: Select all

ERROR: object:<auto follow target> function:<Trigger 11>
<[string "function Trigger11()..."]:2 bad argument #1 to 'find' (string expected, got nil)>

And I do not follow.

So clearly I still don't quite understand the whole targeting thing. I really want to. What am I doing wrong?

insted of:

Code: Select all

Pattern: ^af (\w+)$
Script: target = matches[2]

try

Code: Select all

Pattern: ^af (.+)$
Script: target = matches[2]

this should allow for a string of word, insted of a single word

open the debug console, then try and execute the trigger with the console OPEN, see if it tells you anything.
