I recently got stuck while making a C++11/SDL game engine, and I can use some advice. Ideally, what I want to do is the following: 1. create enumeration representing all sprites to add to a spritebank 2. create a vector of filenames, and using the enumeration add each filename to the vector 3. go through all loaded filenames, and using the enum create sprites with specific properties but I can't quite find a way to do the second and third step without having my compiler belch a bunch of errors. Any ideas as to how to get it to work? The code I used is below (feel free to say if there's any info missing) //application class that starts the program// std::vector<std::string> files; class App : public Event { private: bool Running; //Running flag enum sprite_file { SPRITE_RING1 = 0, SPRITE_RING2 = 1, SPRITE_END = 2 }; SDL_Window* graphicsWindow; //The window SDL_Renderer* graphicsRenderer; //The renderer TTF_Font* globalFont; //The global font Timer capTimer; //Frames per second cap timer SpriteBank rings; //Collection of sprites std::string currentSprite; //Filename of sprite in use [...] //initialization function within App// //Initialize spritebank if(!rings.Init(graphicsRenderer)) { printf("Failed to load sprites!"); } //Add two sprites files.emplace(SPRITE_RING1, "media/img/ring/ring1.png"); files.emplace(SPRITE_RING2, "media/img/ring/ring2.png"); //Add two sprites for(auto filename : files) { switch(this->sprite_file) { case SPRITE_RING1: { rings.AddSprite(filename, 40, 40, 40, 20, 20); break; } case SPRITE_RING2: { rings.AddSprite(filename, 40, 40, 40, 20, 20); break; } default: continue; break; } } currentSprite = SPRITE_RING1; EDIT: The file.emplace() functions give this error, switch(this->sprite_file) gives this, and the alternative, switch(sprite_file) gives this |

I don't see where you declared 'files' Also the compiler errors would be nice to see |

My problem is that my attention span is only a few days so I can never get big projects done. Does anyone have any advice to stay motivated? |
