Cocos2d-x adaptive android different resolution, using multiple sets of resources

Although the cocos2d-x comes with three modes to adapt to the screen, but there are still some problems, will produce Black edge, so we still need multiple sets of resources to adapt to the screen. Here I have selected four resolutions:, and. I have created four folders in the resource Directory and placed multiple sets of background images. Just add the following function calls to AppDelegate. [Cpp] void AppDelegate: ScreenAdaptive () {CCSize szFrame = CCEGLView: Export dopenglview ()-> getFrameSize (); float Proportion = szFrame. width/szFrame. height; const int num = 4; float diff [num] = {fabs (Proportion-(9.0/16), fabs (Proportion-(3.0/5 )), fabs (Proportion-(2.0/3), fabs (Proportion-(3.0/4)}; int yy =-1; for (int I = 0; I <num; I ++) if (diff [I]>-0.000001) & (diff [I] <0.000001) {yy = I; break ;} if (yy =-1) {int min = diff [0]; yy = 0; for (int I = 1; I <num; I ++) if (diff [I] <min) {min = diff [I]; yy = I ;}} switch (yy) {case 0: {std :: vector <string> searchPaths; searchPaths. push_back ("9x16"); CCFileUtils: sharedFileUtils ()-> setSearchPaths (searchPaths); CCEGLView: Export dopenglview ()-> Export (648,1152, kResolutionShowAll); break ;} case 1: {std: vector <string> searchPaths; searchPaths. push_back ("3x5"); CCFileUtils: sharedFileUtils ()-> setSearchPaths (searchPaths); CCEGLView: Export dopenglview ()-> Export (, kResolutionShowAll); break ;} case 2: {std: vector <string> searchPaths; searchPaths. push_back ("2x3"); CCFileUtils: sharedFileUtils ()-> setSearchPaths (searchPaths); CCEGLView: Export dopenglview ()-> Export (640,960, kResolutionShowAll); break ;} case 3: {std: vector <string> searchPaths; searchPaths. push_back ("3x4"); CCFileUtils: sharedFileUtils ()-> setSearchPaths (searchPaths); CCEGLView: Export dopenglview ()-> setDesignResolutionSize (624,832, kResolutionShowAll ); break ;}} here is a brief introduction to setSearchPaths. In the latest version, setResourceDirectory is no longer available and is replaced by setSearchPaths. The following is a description of setSearchPaths: [cpp]/*** Sets the array of search paths. ** You can use this array to modify the search path of the resources. * If you want to use "themes" or search resources in the "cache", you can do it easily by adding new entries in this array. ** @ note This method cocould access relative path and absolute path. * If the relative path was passed to the vector, CCFileUtils will add the default resource directory before the relative path. * For instance: * On Android, the default resource root path is "assets /". * If "/mnt/sdcard/" and "resources-large" were set to the search paths vector, * "resources-large" will be converted to "assets/resources-large" since it was a relative path. ** @ param searchPaths The array contains search paths. * @ see fullPathForFilename (const char *) * @ since v2.1 */[cpp] // set searching paths to "/mnt/sd/example" and "/data/org. cocos2dx. example "vector <string> searchPaths; searchPaths. push_back ("/mnt/sd/example"); searchPaths. push_back ("/data/org. cocos2dx. example "); CCFileUtils: setSearchPaths (searchPaths); // engine will find" 1.png" in/mnt/sd/example, if there it is not found, then engine will find "1.png" in/data/org. cocos2dx. example // if not found, engine will find "1.png" in Resources/(this path is platform dependent) [cpp] CCSprite * pSprite = CCSprite
