Losing precision in 2d Texture.

Ajrarn777

I suppose this is a very common problem, and maybe there is no solution, but I try anyway.

I'm making the border of a zone by assembling different Texture. The Texture Border is 3 pixels wide.

When I change the application screen size, I lost precision of the texture, and sometime the line simply disappear. :angry:

Is there a strategy to prevent (or improve) this problem ? Maybe making the texture twice as big ???

In this example, the left-bottom side have a line removed.

Any suggestion ? Thanks

You need to enforce integer scaling to prevent this kind of artifact when using textures with filtering disabled (or the viewport stretch mode). Note that this will no longer allow the application to be drawn at a smaller window size than the one you specified in the Project Settings.

This is very interesting.
Thanks for the info =) .

But, I don't see any viable solution for my project right now :s .

I want this integer scaling only some specific textures, not on all my screen. For example, if an player used a screen resolution of 1200x3000, and I have designed my screen for 700x1024, it will display large black margins each side (500pixels), and the rendered text will be too small to read (on a mobile phone).

This only works at 1:1 pixel scale. If the window resolution is not the same as the viewport resolution, there will always be an issue (unless you use integer scaling or interpolation). The result is that single pixel lines can disappear or become doubled. You can use linear interpolation (I think it is called filtering on the texture import settings) but this will make the texture look blurry. The better solution is to pick a good base resolution (maybe 1280 x 720) and then use viewport scaling so the pixels don't distort.

Not sure what type of node you're using for the border, but maybe implementing it as a NinePatchRect would help.
