Title: SlicedSprite border offset and Direct3D
Post by: broken on November 04, 2014, 06:44:03 AM

Hi!

I switched back from DFGUI to NGUI and I have a question.

Unity 4.5.5f1, NGUI 3.7.5

I create simple SlicedSprite and looks like the sprite has border offset (attachments). "Use Direct3D 11" settings is disabled.
If I enable "Use Direct3D 11" checkbox in Player Settings, sprite border becomes ok.

If I'm not mistaken a year ago this was not. It is normal behaviour?

The only thing similar that I found to the forum:

Thanks!

Hi broken,

as far as I know it seems to be normal behaviour. I'm currently creating a pixel perfect retro GUI where I can see and "feel" every pixel. At one point I had to use MeshColliders for some buttons and I positioned them without offsets. It turned out that the Hover animation for my buttons started earlier or later depending on which site of the button the mouse entered first.
I then added the offsets and everything works fine now.

I still would like to know the reasoning behind those offsets.


Cheers

DirectX9 has this weird half-pixel offset. If I don't offset by half a pixel, everything becomes blurry. You can google "dx9 half pixel" for more info.
