New line character in string.format

[MaddDogg]

Hi!

I just ran into a problem, I didn't notice ever before.

I have a script, which is at one point supposed to send the player a message.

The text for this message is first read from an xml file, then put into a string.format function and finally used in guiCreateLabel.

It looks like this:

xml file:

<text catg="CHARACTER" identifier="LEVEL_UP_TEXT" text="You just leveled up!\nNew level: %d" />

 

Lua script:

GUI_LevelUp["text"] = guiCreateLabel(1606,480,148,32,string.format(getLanguageText("CHARACTER", "LEVEL_UP_TEXT"), getElementData(getLocalPlayer(), "level")),false)

My problem now is that the new line character ('\n') is output not as a new line but rather as the characters '\n' itself.

This is caused by string.format for some reason.

Now I don't really know, how to get the new line into the final string.

Can someone please help me with this issue?

And no, I can't just leave the xml stuff out of it and put the string directly into string.format

Thanks in advance,

Madd

try doing something like:

GUI_LevelUp["text"] = guiCreateLabel(1606,480,148,32,string.gsub(string.format(getLanguageText("CHARACTER", "LEVEL_UP_TEXT"), getElementData(getLocalPlayer(), "level")), "\\n", "\n"),false)

i didnt test it, but maybe it will work i had same problem when i was scripting in another programming lang few days ago

Thanks! It worked!

But why is string.format escaping the new line character?

I mean, in the original string there is this character. But as soon as string.format processes it, it does that.

And it only happens, when I pass the string through a variable to it instead of directly writing it into the function.

dont ask me maybe somebody knows the reason

The reason is simple, when extracting data from XML file, all backslash (\) are duplicated.

Ohh okay, thank you. Now I understand why.

Thanks for the help.
