I'm trying to add localized texts to a gui. I'm using I18n.format(String string, Object... params) in order to localize the texts.

 

When I do any alternations to the texts (like replacing regular expressions with actual strings or splitting lines using string.split(regEx)), the texts have a prefix "Format error: " on them.

 

My gui drawScreen code:

@Override
public void drawScreen(int par1, int par2, float par3) {
GlStateManager.color(1F, 1F, 1F, 1F);
mc.renderEngine.bindTexture(texture);
drawTexturedModalRect(left, top, 0, 0, guiWidth, guiHeight);
if (world.isRemote) {
	String xPos = I18n.format("guiText.ijc:xPos").replace("%xPos", "" + pos.getX());
	String yPos = I18n.format("guiText.ijc:yPos").replace("%yPos", "" + pos.getY());
	String zPos = I18n.format("guiText.ijc:zPos").replace("%zPos", "" + pos.getZ());

	fontRendererObj.drawString(xPos, left + 16, top + 32, 4210752);
	fontRendererObj.drawString(yPos, left + 16, top + 48, 4210752);
	fontRendererObj.drawString(zPos, left + 16, top + 64, 4210752);
        }
}

 

My en_US.lang file:

guiText.ijc:xPos=x: %xPos
guiText.ijc:yPos=y: %yPos
guiText.ijc:zPos=z: %zPos

 

A visual example of the problem:

I hope I'm not doing something silly...

I18n.format

returns the translated text prefixed with "Format error:" when

String.format

throws an

IllegalFormatException

. You can set a breakpoint in the

catch

block of

Locale#formatMessage

(called by

I18n.format

) to see what this exception is.

 

I suspect it's because you're using a percent sign followed by a letter (and then some other letters) as your own formatting placeholders, but

String.format

is trying to replace these itself and throwing an exception because they're not valid placeholders or there's no format arguments.

 

Do one of the following to fix this:

• Use valid formatting placeholders (e.g.

  %d

  ), pass the format arguments to

  I18n.format

  and remove the

  String#replace

  calls.
  

• Escape the percent sign with another percent sign (

  %%

  ) to prevent

  String.format

  from treating it as a formatting placeholder.

I just replaced the placeholder % with wrapping the word with * and it works... I might look into doing one of the offers to fix the general problem if it appears again, but for now it works. Thanks a lot!

Just out of curiosity, why bother translating coordinate symbols? I am pretty sure they are the same in all languages anyway?

 

also, to convert an int to a String you can use:

String.valueOf(i);
Integer.toString(i);

instead of

"" + i;

which looks a bit cleaner in my opinion 

I'm localizing the coords because I'm putting it in a gui with text and I want the gui to be fully modifiable to other languages, so even if the coords stay the same, there are other places using coordinates and they do have text that is interchangable between languages, so I just want to make it fully modifiable.

 

Thanks for the Integer tip, I actually didn't know that...
