I searched but no answer so I have to come here and asking this coding problem

Post by Flandre » Fri Oct 16, 2020 5:42 pm

Hi everyone hope this is simple.....

temp1="first neko"
nn1=love.graphics.newText(font,tostring(temp1))
nn1=nn1:setf("111",500)

always report argument #3 to 'setf' (string expected, got no value)

Do I have a understanding-problem with "textstring" of "Text:setf( textstring, wraplimit, alignmode )"?

Another thing I want to know is is there a way to format (word wrap) text object directly, without replacing text-content like Text:setf does?

Sorry for my English :( Any understanding-problems just let me know.

That's a quintuple post. Don't do that. If you have something to add, you can edit your own posts; please don't post several times in a row.
Ah...I didn't know that, really sorry, now I know, not again, thank you Nixola :)

If you take a look at the wiki entry for Text:setf: You need to give the function three parameters:
  1. The new text to draw
  2. The number of pixels before wrapping
  3. And the alignment of the text (left, right center or justify)
The error even says so: argument #3 (alignmode) is missing. The function expects as string (e.g. "left"), but there was no third argument.

Personally: I do not know. Can you expand on this: What do you want to achieve?

I added 3rd parameter (I deleted it before post problem on forum because I saw it still reports same error.) I tried it again in past seconds and still reports....ok, a little difference, it reports bad argument #3 to 'setf' (string expected, got nil)

temp1="first neko"
nn1=love.graphics.newText(font,tostring(temp1))
nn1=nn1:setf("111",500,left)

I mean, like:
somewords=love.graphics.newText(...)
somewords=somewords:setf(wraplimit), not include using a new text to replace original text.

or just:
somewords=love.graphics.newFormatText(...)

Anyone could run this scrpit

font = love.graphics.getFont()
font = love.graphics.setNewFont(24)
nn1=love.graphics.newText(font,"222")
nn1=nn1:setf("111",500,left)

always reports: main.lua:4: bad argument #3 to 'setf' (string expected, got nil)

For others, codes still has a incorrect point, should using nn1:seft() not nn1=nn1:setf() because Text:setf() returns nothing that makes nn1 = nothing.

temp1="first neko ssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssss"
nn1=love.graphics.newText(font,tostring(temp1))
nn1:setf(tostring(temp1),500,"left")
function love.draw()
love.graphics.draw(nn1,0,0)
end

Building newFormatTextObject dircetly function eg.

function love.graphics.newFText(cfont,ctext,textObjectName)
textObjectName=love.graphics.newText(cfont,tostring(ctext))
textObjectName:setf(tostring(ctext),500,"left")
return textObjectName
end

nn2=love.graphics.newFText(font,temp1,nn2)
function love.draw(...)
love.graphics.draw(nn2,0,0)
end

Okay, that I understand. But why do you want to do that? What effect do you want to achieve? Do you need a resizeable textbox?

Um, long text will be out of textbox(with a fixed size) if without word wrap, anyway it can build a function for the problem so doesn't matter anymore, it may be better but also may be same performance if love2D has its own function for that, so it's ok with custom function for sloving it, and, is the only way if love2d doesn't have its own function for that.

Add:What I want is a text-based game, maybe with many textboxs sametime on the screen.
