Babybus-u3d技术交流-取出图集中的精灵
using UnityEngine;
using System.Collections;
using UnityEditor;
using System.IO;
using System.Text.RegularExpressions;
public class UIAtlasContextMenu
{
[MenuItem("CONTEXT/UIAtlas/Extract Sprite List", true)]
static bool ExtractSpriteListValidation(MenuCommand menuCommand)
{
return AssetDatabase.GetAssetPath(menuCommand.context) != "";
}
[MenuItem("CONTEXT/UIAtlas/Extract Sprite List")]
static void ExtractSpriteList(MenuCommand menuCommand)
var atlas = menuCommand.context as UIAtlas;
string path = AssetDatabase.GetAssetPath(atlas);
string directory = Regex.Match(path, "[^\\.]*").Value + "/";
if (!Directory.Exists(directory))
Directory.CreateDirectory(directory);
foreach (UISpriteData spriteData in atlas.spriteList)
{
Debug.Log("Extract Sprite " + spriteData.name);
UIAtlasMaker.SpriteEntry se = UIAtlasMaker.ExtractSprite(atlas, spriteData.name);
if (se != null)
{
byte[] bytes = se.tex.EncodeToPNG();
File.WriteAllBytes(directory + spriteData.name + ".png", bytes);
AssetDatabase.ImportAsset(directory + spriteData.name + ".png");
if (se.temporaryTexture) Object.DestroyImmediate(se.tex);
}
}
}
}
NGUI有图集打包功能，以上代码是逆向，把打包好的图集分解，提取出图集中的原始精灵。
