Offset adjusting itself specifically for "." to "1", even when using default font

[karnoldDWG]

Hello! Sorry if this question has been asked before, but I'm running into a specific issue when converting .XML into something usable for our game's framework-- it could definitely be something on our end but I thought I'd just ask if anyone had any ideas here: the font previews fine in SnowB, but when used in our game engine, "." to "1" kerning is adjusted in a way that causes them to completely overlap. When I view it in SnowB, I see the exact adjustment being applied automatically, but the numbers do not overlap in the preview in SnowB. When erasing the automatic kerning adjustment in SnowB (which makes it look weird in the preview), this fixes it in our framework.

Just wondering if anyone has any clues. Thanks!

Just to clarify, this happens even when exporting just the default font out of SnowB.

Hi @karnoldDWG,

SnowBamboo follows the AngelCode BMFont format specification:

• File format: https://www.angelcode.com/products/bmfont/doc/file_format.html
• Rendering logic: https://www.angelcode.com/products/bmfont/doc/render_text.html

According to the spec, kerning should work as follows:

1. Kerning application: The amount value should be added to the x position after advancing by xadvance.
2. Kerning direction:
   • Positive values = increase spacing (move second character right)
   • Negative values = decrease spacing (bring characters closer)

The overlap you're experiencing suggests your game engine might be interpreting the kerning values differently than the AngelCode specification.

To help diagnose further:

• Could you share your exported files (both the XML/FNT descriptor and the PNG texture atlas)? We can analyze them together to see if there's an
  issue with the export or if it's an engine interpretation difference.
• Or, if you can check your engine's rendering logic to see how it applies the kerning amount, that would help identify the discrepancy.

Looking forward to solving this with you!
