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
*/
