How to set a texture resource to texture type "GUI" by script?
Using the editor, I can select a texture asset (PNG file) and set its "texture type" to "GUI" manually. This allows it to be displayed pixel-perfect in the UI.
My game generates PNG files automatically (saved in the resources folder) that are then displayed in the UI. So it needs to load these at runtime with texture type "GUI" instead of the default "texture".
So how can you set the texture type of assets through scripting?
FYI, saving textures to the resources folder only works in the editor. It will not work in a build.
I was sort-of aware of that. Shouldn't be an issue tho, when running the game as stand-alone build it should save this stuff to some user data folder, not resources.
For pixel perfect, have you looked at GUITextures using pixelInset? That's what they are advertised as being for.
You can set the guitexture directly without saving as png doing this ...
var tex = new Texture2D(1, 1);
tex.SetPixels(new Color[] {Color.white});
tex.Apply();
style.normal.background=tex;
Or you can change import settings
var bytes=tex.EncodeToPNG();
string path="Assets/Resources/... .png";
File.WriteAllBytes(path,bytes);
AssetDatabase.Refresh();
AssetDatabase.ImportAsset(path);
TextureImporter importer = AssetImporter.GetAtPath(path)as TextureImporter;
importer.textureType=TextureImporterType.GUI;
AssetDatabase.WriteImportSettingsIfDirty(path);
Thanks this was more or less what I was looking for. Only didn't expect it would be editor only. It's for a map editor that generates map preview thumbnails. Since it turns out I need to rescale the final thumbnail textures anyway I'm just importing them as the standard texture type now.
