text is not showing all characters

[cschua]

Hello,

Even with the recent updates on the engine I'm still having issues when showing text on screen. It's frequent that some letters are not showing up on screen. I'm reusing 2 font resources with 6 text objects. I believe when I use the resource more than once, the letters do not show up for the other text objects.

My code...

9.         this.mEngine.getTextureManager().loadTexture(this.mFontTexture);
10.         this.mEngine.getFontManager().loadFont(this.mFontScore);
11.         //
12.         this.mFontTexture = new Texture(256, 128, TextureOptions.BILINEAR);
13.         this.mFontMenu = FontFactory.createFromAsset(this.mFontTexture, this, "UnrealTournament.ttf", textSize2, true, Color.WHITE);
14.         this.mEngine.getTextureManager().loadTexture(this.mFontTexture);
15.         this.mEngine.getFontManager().loadFont(this.mFontMenu);
16.         // ...
17. }

then at different location of the code I use the resource...

when I replaced

FontFactory.createFromAsset(this.mFontTexture, this, "UnrealTournament.ttf", textSize1, true, Color.WHITE);

with this

new Font(this.mFontTexture, Typeface.create(Typeface.DEFAULT, Typeface.BOLD), textSize1, true, Color.WHITE);

the bug went away and so far I can see all the leters.

So, I'm guessing FontFactory.createFromAsset has a bug when multiple text objects are using the resource.

Anyone experiencing the same?

Hi, you should re-test this bug again and again.
This kind of bug is a randomize-bug.

[cschua]

yeah it is still happening with Typeface font.

i'm going to look at other options.

Had I asked what device you are using

Can you make a minimal example (zipped project) you are still experiencing this issue

Best Regards,
Nicolas

[cschua]

my device is droid 1 and 2.

but i dont think it's the device since the emulator on my pc / laptop does the same thing. it's rare in the emulator with Typeface, but on the phone it happens 80% of the time.

I will write a smaller example and post it here tomorrow.

hey Nicolas,

I sent you a message. I sent you a megaupload link to dl part of my code where the text is missing characters.

I'm facing the exact same problem. Some of my text characters are not showing. I reuse the same Font instance for those Texts.

Did you find the reason for that unexpected behavior, please?

Do you think that it may be linked to the size of the underlying Texture instance used to create the Font object? I did not find any material which explains what size the Texture used to create a Font instance should be? Should it be dependent on the font size?

Thank you for your help. Regards,
Édouard

To anyone having this issue, it's just because your font texture is too small so some letters or numbers are not being created properly, just make the texture bigger and it will fix it.

[Doudou]

Thank you very much for this answer.

This leads to the following question: how big should be the Texture used to create a Font? Sorry to be that dump in Open GL.

Thank you for your time and support. Regards,
Édouard
