cocos2d-x 资源搜索路径 addSearchPath addSearchResolutionsOrd

今天遇到了资源找不到的问题，看了代码，了解了下cocos2d的资源搜索方式

新建一个项目，我的路径F:/projects/luatest/

CCFileUtils::getInstance()->addSearchPath("F:/projects/luatest2");  
CCFileUtils::getInstance()->addSearchPath("src");  
/* 
此时 
searchPath 有3个 
1. "F:/projects/luatest/"  默认项目路径 
2. "F:/projects/luatest2" 
3. "F:/projects/luatest/src/" 
 
*/  
CCFileUtils::getInstance()->addSearchResolutionsOrder("res");  
  
/* 
resourceDirectory 有2个 
1. ""    默认，空 
2. "res/" 
*/  
  
//测试：寻找close.png，这个文件不存在，看看cocos2d搜索了哪些路径CCFileUtils::getInstance()->fullPathForFilename("Images/close.png");  
/* 
cocos2d搜索的时候，会把文件名分拆成两部分，具体看CCFileUtils.cpp的FileUtils::getPathForFilename 
file_path = "Images/" 
filename ="close.png" 
*/  
  
/* 
//搜索路径组合方式： searchPath + file_path + resourceDirectory + filename 
 
最终搜索的所有路径 
F:/projects/luatest/Images/close.png 
F:/projects/luatest/Images/res/close.png 
F:/projects/luatest2/Images/close.png 
F:/projects/luatest2/Images/res/close.png 
F:/projects/luatest/src/Images/close.png 
F:/projects/luatest/src/Images/res/close.png
