[游戏开发]OnPostprocessTexture unity导入资源设置

unity导入资源的编辑器设置:

防止策划资源乱导入,资源导入需要的格式

AssetPostprocessor

?

预处理:OnPreprocessTexture

TextureImporter imp = (TextureImporter)assetImporter;

获得图片的原始大小

TextureImporter importer = AssetImporter.GetAtPath(path) as TextureImporter;
if(importer == null)
   throw new System.Exception(string.Format("GetRawTexSize failed: importer is null, path={0}", path));

object[] args = new object[2] { 0, 0 };
MethodInfo mi = typeof(TextureImporter).GetMethod("GetWidthAndHeight", BindingFlags.NonPublic | BindingFlags.Public | BindingFlags.Instance);
mi.Invoke(importer, args);

通过反射使用TextureImporter.GetWidthAndHeight

imp.textureType = TextureImporterType.Sprite;
imp.spriteImportMode = SpriteImportMode.Single;
imp.spritePackingTag = packingTag;
imp.npotScale = TextureImporterNPOTScale.None;
imp.mipmapEnabled = false;
      imp.isReadable = true;
imp.alphaIsTransparency = true;
imp.wrapMode = TextureWrapMode.Clamp;
imp.textureCompression = TextureImporterCompression.Uncompressed;

设置格式

后处理:OnPostprocessTexture
