Solved :gmatch() [TFS 1.2]

[Aeronx]

Hello otlanders!

I am trying to learn a bit more here, so maybe you can instruct me.

I have started working with :gmatch and for easy tests I tested it with monster names.

local desc = target:getName():gmatch('%d')
local lvl = tonumber(desc())
print(lvl)

the targeted monster has the name "Monster 1".

But i get error in "tonumber (value expected)", so i guess, my gmatch is not correct. What am I doing wrong?

Thank you for your time!

Could you print target:getName() ?

I tried in Lua DEMO and for me its working...
Lua: demo

local target = 'Monster 1'
local desc = target:gmatch('%d')
local lvl = tonumber(desc())
print(lvl)

PS if you want more than 1 digir, use '%d+'

damn.. its working.. the problem was monster name was monster [1]

So for more testing, i went farther.

Now monster name is monster [ii. 1]
so i changed the code like this

local target = 'Monster [ii. 1]'
local desc = target:gmatch('[ii. %d]')
local lvl = tonumber(desc())
print(lvl)

but it prints nil, what should i do in this case? Thank you!

EDIT: nvm i solved it myself. gmatch should be the same ('%d')

And what do you want to retrieve? Just the number? Then the same code should work for you, do not change the regex.

If you want to get the complete text in the brackets, use this regex: target:gmatch('%[ii%.%s%d%]')
