[Position out of bounds!]

原因是我们项目今天有个美术上传了本地修改的meta文件，应该是导致了两个资源的GUID冲突了，最后读文件的时候读取到其他的文件去了，解决方案是全部重新Import一次，或者把Library目录删掉 重新打开Unity，或者还原这几个Meta文件

为了方便检查GUID是否有冲突，写了个python脚本
把下面的脚本放到Assets目录中，运行即可

# check_guid_repeat.py
import os
import re

def get_meta_files():
    for root,dirs,fs in os.walk('./'):
        for f in fs:
            if f.endswith('.meta'):
                yield root+'/' +f

def get_guid(f, t):
    if not os.path.exists(f):
        print(f + ' not exists')
        return
    fr = open(f, 'r')
    txt = fr.read()
    match = re.search('guid: (.*)', txt)
    guid = match.group(1)
    if guid in t:
        print('文件: '+ t[guid] + '\n和\n ' + f +'\nguid冲突了\nguid: ' + guid)
    else:
        t[guid] = f
    

if '__main__' == __name__:
	curDir = os.getcwd()
    t = {}
    f_cnt = 0
    for f in get_meta_files():
        get_guid(curDir + '/' +f, t)
        f_cnt = f_cnt +1
    print('check done, f_cnt: ' + str(f_cnt))
