Android Resolution Problem [SOLVED]

[test]

When I open my love file, the screen resolution is not 1920x1080. But my phone's resolution is 1920x1080. When I open with an old version of Love, it works in 1920x1080. I do not use google play version. I use the updated APK verslon which is on the love's website. I used t.window.width and t.window.height in conf.lua but nothing changed. How can I set resolution to my phone's current resolution on Android? Thanks...

So if I use old version of love, dpi is off as default right? Because there is no problem for old versions.

Yes you could simply use older version if you don't need new version's features. This problem should be fixed in the future versions.

Note that it's not a problem of resolution. The resolution is the same. It's just that the coordinates don't match pixels.

A quick and dirty workaround is to use this at the beginning of love.draw:

Code: Select all

  love.graphics.scale(1/love.window.getDPIScale())

and use love.graphics.getPixelWidth etc instead of love.graphics.getWidth etc.

Thanks pgimeno. But why did you say dirty for the code you writed? It works. If I use this code and build APK, is it bad pratice? What is the correct way?

[pgimeno]

It doesn't cover all functions, e.g. canvas creation, and if you use vertex shaders, it may not work properly, but for a simple game it works.

Edit: The "correct" way is to use the coordinates unmodified, and use love.window.toPixels/fromPixels if you really need to convert to/from real pixels. You still have the full resolution if you draw images.

Thanks. I think I am going to solve this situation (not a problem) by creating a 1920x1080 canvas and setting dpi to 1.
