Detailed Description

template<typename Manifest>
class ml::AssetsManager< Manifest >

Unified asset accessor for textures, fonts, and sound buffers.

AssetsManager<Manifest> combines TextureManager, FontManager, and SoundManager into a single class with overloaded get() methods. Each overload is enabled only when the manifest declares the corresponding enum (Images, Fonts, or Sounds), so attempting to retrieve an asset type the manifest does not declare is a compile error rather than a runtime failure.

When to use AssetsManager vs individual managers

Scenario	Recommended
Only textures needed	TextureManager<Manifest>
Only fonts needed	FontManager<Manifest>
Mix of textures, fonts, sounds	AssetsManager<Manifest>
Also need config values	Context<Manifest>

Usage

class MyManifest : public ml::Manifest {
public:
    enum class Images { Background, Player };
    enum class Fonts  { Main };
    enum class Sounds { Jump };
private:
    inline static const auto _ = [](){
        set(Images::Background, "assets/bg.png");
        set(Images::Player,     "assets/player.png");
        set(Fonts::Main,        "assets/main.ttf");
        set(Sounds::Jump,       "assets/jump.wav");
        return 0;
    }();
};
 
// All three asset types via one manager
const sf::Texture&     bg  = ml::AssetsManager<MyManifest>::get(MyManifest::Images::Background);
const sf::Font&        fnt = ml::AssetsManager<MyManifest>::get(MyManifest::Fonts::Main);
const sf::SoundBuffer& sfx = ml::AssetsManager<MyManifest>::get(MyManifest::Sounds::Jump);
 
// Default font (built-in Arial) — no manifest entry needed
const sf::Font& arial = ml::AssetsManager<MyManifest>::getDefaultFont();

get() [1/3]

template<typename Manifest>

template<typename M = Manifest>

std::enable_if_t< has_Font< M >::value, const sf::Font & > ml::AssetsManager< Manifest >::get ( typename M::Fonts font )

static

Retrieve a cached sf::Font by manifest enum value.

Only available when Manifest declares a Fonts enum.

Parameters

font	The Fonts enum value identifying the font.

Returns

Const reference to the cached sf::Font.

template<typename Manifest>

template<typename M = Manifest>

std::enable_if_t< has_Image< M >::value, const sf::Texture & > ml::AssetsManager< Manifest >::get ( typename M::Images image )

static

Retrieve a cached sf::Texture by manifest enum value.

Only available when Manifest declares an Images enum.

Parameters

image

The Images enum value identifying the texture.

Returns

Const reference to the cached sf::Texture.

get() [3/3]

template<typename Manifest>

template<typename M = Manifest>

std::enable_if_t< has_Sound< M >::value, const sf::SoundBuffer & > ml::AssetsManager< Manifest >::get ( typename M::Sounds sound )

static

Retrieve a cached sf::SoundBuffer by manifest enum value.

Only available when Manifest declares a Sounds enum.

Parameters

sound

The Sounds enum value identifying the sound buffer.

Returns

Const reference to the cached sf::SoundBuffer.

getDefaultFont()

template<typename Manifest>

template<typename M = Manifest>

std::enable_if_t< has_Font< M >::value, const sf::Font & > ml::AssetsManager< Manifest >::getDefaultFont ( )

static

Return the built-in Arial font.

Only available when Manifest declares a Fonts enum. Delegates to FontManager::getDefault().

Returns

Const reference to the built-in sf::Font.
