Font appears completely black

[slavik262]

I've created fonts using the advanced font tool, but the characters always appear completely black, regardless of what colors I use.

Any ideas what could be happening?

The font tool create an image at the desired size ? It's seem strange but if I get you it's like only alpha channel is working .

[slavik262]

Yes, the font image looks perfect, but when I load it into Irrlicht, it only gives respect to alpha, like you said. Every character is completely black.

I thinked about it and really have no idea. Maybe you should try to create a small project just drawing font character to be sure that it's not linked with an error elsewhere.

very strange! it always worked for me importing a "font.xml" from the advanced tool. yaeah create a small projects and post to us (and if you don't want to use your font use another font type, if other fonts give you the same result)

Font image (a PNG):


Code (MSVC 2010, Irrlicht 1.7.1 standard build):

Code: Select all

#include <irrlicht.h>
using namespace irr;
using namespace core;
using namespace video;
using namespace scene;
using namespace gui;

#pragma comment(lib, "irrlicht.lib")

int main()
{
	SIrrlichtCreationParameters cp;
	cp.AntiAlias = 8;
	cp.Bits = 32;
	cp.DriverType = video::EDT_DIRECT3D9;

	IrrlichtDevice* device = createDeviceEx(cp);

	IVideoDriver* vd = device->getVideoDriver();
	vd->setTextureCreationFlag(video::ETCF_ALWAYS_32_BIT, true);
	ISceneManager* sm = device->getSceneManager();
	IGUIEnvironment* guienv = device->getGUIEnvironment();
	guienv->getSkin()->setFont(guienv->getFont("displayfont.png"));
	guienv->addStaticText(L"Woohoo!", rect<s32>(10, 10, 200, 100));

	while(device->run())
	{
			vd->beginScene(true, true, SColor(255, 127, 127, 127));
			guienv->drawAll();
			vd->endScene();
	}
	return 0;
}

Result:

Code: Select all

	guienv->getSkin()->setFont(guienv->getFont("displayfont.png"));

isn't there a xml file creates by the font tool you should load ???

[Steel Style]

Yes like Acki said your xml file should load the font handling alpha and other purpose.

[slavik262]

You can also export from the font tool a single .png.

Loading an xml font generated from the tool gives the same results. If you don't believe me, I can post another example, but this doesn't seem to be the issue here.

[slavik262]

Confirmed. It's happening with an XML font too (same code as above, substituting the png for the appropriate xml file). Plus to make sure it wasn't something I broke, I just did a fresh download of 1.7.1, and the same thing still happens.

Could this be some material thing? I have no idea why this is happening. It's not like I have weird setup either (GTX 260, Windows 7 32-bit, latest drivers).

Hi I have TEH clue. After seeing your post I downloaded Irrlicht (what a shame that I didn't have it already and made investigation).

Your text is displaying black cause it's the skin's text color. So to display it at the image just change :

Code: Select all

IGUIStaticText* staticText = guienv->addStaticText(L"Woohoo!", rect<s32>(10, 10, 200, 100));
   staticText->setOverrideColor(SColor(255, 255, 255, 255));

[slavik262]

Awesome! I figured it would be something silly. Thanks for the help!

[serengeor]

I was having the same problem and I still have
The solution worked for textbox, but it didn't work for Button, it has no setOverrideColor function

[slavik262]

Instead of setting the override color, go into the skin your GUI is using and set the color that the text is drawn with.

[serengeor]

Im using advanced font tool, and the letter color is set to gradient, so what am I going to set there ? :/
