TexturePacker 可以通過命令行方式，批量生成圖集，TexturePacker相關(guān)命令可以參考 https://blog.csdn.net/u014065445/article/details/54289787

unity中使用的方式是，通過C#中的Process類，創(chuàng)建一個(gè)獨(dú)立進(jìn)程，執(zhí)行命令行腳本，完成圖集生成和切分

Mac平臺(tái)的shell腳本

./TexturePacker \ --sheet $3/$1_{n}.png \ --data $3/$1_{n}.txt $2 \ --format unity \ --trim-sprite-names \ --basic-sort-by Name \ --basic-order Descending \ --max-size $4 \ --size-constraints POT \ --force-squared \ --border-padding 1 \ --shape-padding 2 \ --disable-rotation \ --trim-mode None \ --disable-auto-alias \ --multipack

Windows平臺(tái)的bat腳本

@echo off start TexturePacker.exe %2 --sheet %3/%1_{n}.png --data %3/%1_{n}.txt %2 ^ --format unity --trim-sprite-names --basic-sort-by Name --basic-order Descending ^ --max-size %4 --size-constraints POT --force-squared --border-padding 1 --shape-padding 2 ^ --disable-rotation --trim-mode None --disable-auto-alias --multipack --extrude 0

為了防止誤操作，這里對可打圖集的資源目錄做了限制

[MenuItem("Assets/Build Atlas/Build For Folder", true)]static bool ValidateBuildForSelectedFolder(){string assetPath = AssetDatabase.GetAssetPath(Selection.activeObject);string[] tempList = assetPath.Split('/');if(assetPath.Contains(spriteFolder) &&tempList.Length > 1){return true;}return false;}
