背景是我有几百个角色gif资源，每个都有：站立、攻击、技能攻击的gif，我想用此资源作2d unity游戏，因此第一关就是如何把gif转成unity动画
GIF 转 PNG —— http://blog.csdn.net/leinchu/article/details/24806433 ，不再赘述了。
之后是批量gif用tp打包，我用php写了一个脚本遍历目录，下的gif把他们重命名并每个角色建立一个文件夹，把它的所有动作的png序列移动到他自己的目录去，再用tp打包：
上php代码，因为我是分布做的，你根据自己的情况改改吧
<?php
$arr = scandir(dirname(__FILE__));
$count = 0;
foreach($arr as $f)
{
if($f==‘.‘||$f==‘..‘ ||!is_dir($f) || in_array($f,array(‘LAsset‘,‘deal_name.php‘))) continue;
$strs = explode("_",$f);
$pre = $strs[0];
$id = str_replace(‘.png‘,‘‘,$strs[1]);
$num = intval(preg_replace("/[^\d]/","",$strs[2]));
$folder = ‘bb_‘.$id;
if(!file_exists($folder)) mkdir($folder);
if($num<1) $num =1;
$cmd = "move ".$f.‘ ‘.$folder.‘/‘.$pre.‘_‘.$num.‘.png‘;
exec($cmd);
$cmd = ‘C:\TexturePacker\bin\TexturePacker --trim-sprite-names --inner-padding 1 --disable-rotation ‘.$f.‘ --data ‘.$f.‘/‘.$f.‘.txt --format unity --sheet LAsset/‘.$f.‘.png --max-width 8192 --max-height 8192‘;
exec($cmd);
$txt = file_get_contents($f.‘/‘.$f.‘.txt‘);
$arr =(array) json_decode($txt);
$a = array();
$h = $arr[‘meta‘]->size->h;
$arr = (array) $arr[‘frames‘];
//var_dump($arr);die();
foreach($arr as $name=>$fr){
$a[] = $name.‘,‘.$fr->frame->x.‘,‘.$fr->frame->y.‘,‘.$fr->frame->w.‘,‘.$fr->frame->h
.‘,‘.$fr->spriteSourceSize->x//用于计算Pivot
.‘,‘.$fr->spriteSourceSize->y
.‘,‘.$fr->spriteSourceSize->w
.‘,‘.$fr->spriteSourceSize->h
.‘,‘.$h//tp的原点在左上角，unity的在右下角，需要用图集高度来转换
.‘,‘.$fr->sourceSize->w
.‘,‘.$fr->sourceSize->h
;
}
file_put_contents(‘LAsset/‘.$f.‘.txt‘,implode("\r\n", $a));
echo $f." OK\n";
//if($count++<5) echo $cmd."\n";else break;
}
之后是自动把png图集转换成sprite集合，我写了脚本，你只要把这个脚本放进你的项目就可以了，然后再asset目录下建立个目录LAsset，右键这个目录把png图集导入进来，就会自动转成sprite集合了
using UnityEngine;
using System;
using System.Collections;
using System.Collections.Generic;
using UnityEditor;
using System.IO;
/*
Your origin picture diretory should be like:
/folder
/folder/LAsset/hero_1
/folder/LAsset/hero_1/spriteAltas.png
/folder/LAsset/hero_1/spriteAltas.txt
/folder/LAsset/hero_2/spriteAltas.png
/folder/LAsset/hero_2/spriteAltas.txt
spriteAltas.txt should be in format of "stand_1,x,y,width,height\r\nstand_2,x,y,width,height\r\nattack_1,x,y,width,height\r\nattack_2,x,y,width,height\r\nattack_3,x,y,width,height"
and finally you will got two prefabs(hero_1, hero_2) both of them has a sprite which has five members(sprites): stand_1,stand_2,attack_1,attack_2,attack_3

因为在导入过程中sprite没有生成，也没有生成后再调用的方法，所以只能再通过一个菜单来批量转换为prefab，把下面的脚本放到你的项目里面，在unity里面选中Asset/LAsset目录，点击菜单Assets/+> Build Prefabs From Selection...预制体就会被打包到Resources下（具体自己改路径吧）
using UnityEngine;
using UnityEditor;
using System.IO;
using System;
using System.Collections;
using System.Collections.Generic;
public class LExportPrefabs
{
private static string[] state_type = new string[]{"stand","attack","skill"};
[MenuItem("Assets/+> Build Prefabs From Selection...")]
static void LExportResource ()
{
//List<string> pathList = new List<string> ();
UnityEngine.Object[] objs = Selection.GetFiltered (typeof(UnityEngine.Object), SelectionMode.DeepAssets);
foreach (UnityEngine.Object _obj in objs) {
string path = AssetDatabase.GetAssetPath (_obj);
Utils.log (path);
if (Path.GetExtension (path) == ".png" && path.IndexOf (LAssetPostprocessor.autoPathMark) != -1) {
string filename = Path.GetFileName (path);
string spriteName = filename.Replace (".png", "");
//pathList.Add (path);
Utils.log (path + " creating prefab for " + spriteName + "...");
GameObject obj = new GameObject (spriteName);
obj.AddComponent<SpriteRenderer> ();
TurnModeRPGAnimator animator = obj.AddComponent<TurnModeRPGAnimator> ();
List<Dictionary<int, int>> frameOrderOfState = new List<Dictionary<int, int>> ();
frameOrderOfState.Add (new Dictionary<int, int> ());
frameOrderOfState.Add (new Dictionary<int, int> ());
frameOrderOfState.Add (new Dictionary<int, int> ());
UnityEngine.Object[] arr = AssetDatabase.LoadAllAssetsAtPath (path);
int len = arr.Length;
//List<Sprite> sprites = new List<Sprite> ();
Utils.log ("length: " + len);
for (int i=0; i<len; i++)
if (arr [i] is Sprite) {
for (int j=0; j<3; j++)
if (arr [i].name.IndexOf (state_type [j]) != -1) {
frameOrderOfState [j].Add (Utils.parseInt (arr [i].name.Replace (state_type [j] + "_", "")), animator.sprites.Count);
break;
}
animator.sprites.Add (arr [i] as Sprite);
}
int idx = 0;
foreach (Dictionary<int, int> item in frameOrderOfState) {
int[] arrFrames = new int[item.Count];
for (int i=0; i<item.Count; i++)
arrFrames [i] = item [i+1];
if (idx == 0)
animator.standFrames = arrFrames;
else if (idx == 1)
animator.attackFrames = arrFrames;
else
animator.skillFrames = arrFrames;
idx++;
}
animator.dics.Add(1,2);
animator.dics.Add(2,317);
PrefabUtility.CreatePrefab ("Assets/Resources/Pets/" + spriteName + ".prefab", obj);
GameObject.DestroyImmediate (obj);
Utils.log ("OK");
}
}
}
}
UnityEngine.GameObject _obj = Resources.Load ("Pets/bb_" + id) as GameObject;
if (_obj != null) {
Utils.log ("Resources loaded OK");
} else
Utils.log ("Resources failt to load");
Instantiate (_obj, new Vector3 (id % 3, 0, 0), new Quaternion ());
