cocos2dx 游戏plist与png完美切成小图python代码
首先需要一份python的切图程序：
1 #python2.5 unpack_plist.py birdfly2

4 #! /usr/lical/bin/python
5 import os,sys
6 from xml.etree import ElementTree
7 from PIL import Image

10 d = {}
11 for index, item in enumerate(tree):
12 if item.tag == 'key':
13 if tree[index+1].tag == 'string':
14 d[item.text] = tree[index + 1].text
15 elif tree[index + 1].tag == 'true':
16 d[item.text] = True
17 elif tree[index + 1].tag == 'false':
18 d[item.text] = False
19 elif tree[index+1].tag == 'dict':
20 d[item.text] = tree_to_dict(tree[index+1])
21 return d

94 filename = sys.argv[1]
95 plist_filename = filename + '.plist'

97 if (os.path.exists(plist_filename) and os.path.exists(png_filename)):
98 gen_png_from_plist( plist_filename, png_filename )
99 else:
100 print "make sure you have boith plist and png files in the same directory"
Mac 电脑下可以新建一个文本把程序复制进去，保存后缀名为 .py 并移至与需要切的plist与png文件夹下。
