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
