the last line to the first line, when read a txt file

[comic3344]

code:

Code: Select all

function Initialize()
       file = io.open(SKIN:MakePathAbsolute('words.txt'), 'r')
end -- function Initialize

function Update()
                 
         wordsline = file:read("*line")
         SKIN:Bang('!SetOption MeterStrMW Text '..'\" '..wordsline..' \"')
         -- if wordline == nil then 
         --    file:close()
         --    SKIN:Bang('!Refresh') 
         -- end

end -- function Update

i use the "if" to change the position, but something wrong in it~

Please help me, thank you~

So you want the script to output a new line from the text wile with each update cycle? Looks OK to me, but you have misspelled wordsline in the part you commented out. I think you might even simplify your code by just using

Code: Select all

if not wordsline then 
-- ...
end

You probably don't want open a file and leave it open at all times. You would not be able to delete it or move it at all.

The following code will read all the lines of a file into a table, closing the file when it's done. Then on each update it will output the next line, looping around to the beginning again when it's done.

Code: Select all

function Initialize()
	local file = io.open(SKIN:MakePathAbsolute('words.txt'), 'r')
	fLines = {}
	for line in file:lines() do
		table.insert(fLines, line)
	end
	file:close()
	cLine = 1
end -- function Initialize

function Update()
	SKIN:Bang('!SetOption', 'MeterStrMW', 'Text', fLines[cLine])
	cLine = cLine % #fLines + 1
end -- function Update
