How to handle different resolutions?

Unity Engine
1

Does anybody have any recommendations on how to handle sprite in different resolutions? I have some wonderful artwork that looks great on high resolution iPad but doesn’t look great at lower resolutions. How do other people handle this? Do people swap atlases?

I saw a Matrix4x4 solution, which was pretty complicated, but worked perfectly though. I’d rather go for some if-statements and then apply rescaled images.

I think I have a pretty good idea of how to alter the camera so that the artwork stays the same size for different screen sizes. The issue I want to use if how do I use different texture sizes for different screen resolutions. I assume I would check the height of the screen and use different resolutions sprites for either low res or high res.

Just scaling down the high resolution artwork looks terrible.

Ok, maybe I didn’t wrote it well, with rescaling, I meant rescaling it with a external Image Editor (eg Photoshop or GIMP), so it looks good and then check the Height/Width, on which you want to swap your Images.
The same effect can be accomplished with a matrix 4x4 and a Texture Atlas, what is a bit more difficult.

I agree with @Joker_54 rather then scaling your images, you could create x2 images for both retina screens and non retina displays and retrieve the screen size/width and decide which textures to use.

Hope these links help:

Thanks for the links but that isn’t related to sprites.

I understand that I don’t want to automatically scale the artwork at run time. What I want to know is how do I swap the texture of a sprite at runtime between low, medium and high res version? From what I can tell, it’s not possible without a third part solution.

I’m considering having 3 versions of each sprite and I’ll just use the version I need at runtime.

If you end up deciding to go for a 3rd party solution, then 2Dtoolkit is the answer for this.

I did buy that yesterday. Trying to learn it. My first experiment with is resulted in odd behaving with the aspect ration when changing resolutions. I changed the camera to ortho and it seems to help.

OP how about to just change the orthographic camera size at runtime depending on your screen resolution, so all sprites will be scaled-up and down by Unity automatically?.. or you really want to have different type of sprites for different resolutions… I’m not sure if it’s a good approach…

You Have to use Screen.SetResolution(int width, int height, bool fullscreen, int preferredRefreshRate = 0);

Check for current width and height and put the value. Write it on Start() and attach it to a empty game Object of the entry scene.
