Detailed Description

Singleton class to support asset management.

Assets should always be managed by a central loader. Cocos2D appears to have these things all over the place. This helps centralize them. This is particularly useful when implementing scene management.

In scene management, each asset is attached to a scene. This allows you to unload all of the assets for a scene without unloading all assets. It is possible for an asset to be attached to multiple scenes. In that case, the scenes will attach a reference count, and the asset will only be unloaded when all associated scenes are unloaded.

This class is a singleton, in the same way that director is. That mean you should not create new instances of this object (and the constructor is protected for that very reason). Instead, you should use the static method getInstance().

Member Function Documentation

SceneManager* AssetManager::at ( int  scene ) const

inline

Returns the scene manager for the given index.

If the scene is invalid, this method will raise an exception.

Parameters

scene

The index for the scene manager

Returns

the asset manager for the given index

int AssetManager::createScene

(

)

Creates a new scene for managing assets.

The new scene will be set as the current scene.

Returns

the index for the new scene manager

void AssetManager::deleteAll

(

)

Deletes all of the allocated scene managers.

This method will stop the scene managers if they are still active. It will clear the asset manager and future attempts to access the previously allocated scene managers will raise an exception.

void AssetManager::deleteScene

(

int

scene

)

Deletes the scene manager for the given index

This method will stop the scene manager if it is still active. Future attempts to access a scene manager for this index will raise an exception.

Parameters

scene

The index for the scene manager

SceneManager* AssetManager::getCurrent ( ) const

inline

Returns the scene manager for the current scene.

If there is no active scene, this method will return nullptr.

Returns

the asset manager for the current scene

int AssetManager::getCurrentIndex ( ) const

inline

Returns the index for the current scene.

If there is no current scene, this method will return -1.

Returns

the index for the current scene.

static AssetManager* AssetManager::getInstance ( )

inlinestatic

Returns a reference tot he global asset manager.

Returns

a reference tot he global asset manager.

bool AssetManager::hasScene ( int  scene ) const

inline

Returns True if scene corresponds to an allocated scene.

In general, this method will return false if scene was deleted. However, the scene identifier may be reused by later allocations.

Returns

True if scene corresponds to an allocated scene.

void AssetManager::init ( )

static

Initializes the global asset manager.

This should be called when the application starts

SceneManager* AssetManager::operator[] ( int  scene ) const

inline

Returns the scene manager for the given index.

If the scene is invalid, this method will raise an exception.

Parameters

scene

The index for the scene manager

Returns

the asset manager for the given index

void AssetManager::setCurrentIndex ( int  scene )

inline

Sets the index for the current scene.

If there is no current scene, this method will return -1.

Parameters

scene

The index for the current scene.

void AssetManager::shutdown ( )

static

Stops the global asset manager.

This releases all of the allocated scene managers. It should be called when the application quits.

void AssetManager::startAll

(

)

Starts all of the allocated scene managers.

void AssetManager::startScene

(

int

scene

)

Starts the scene manager for the given index

Parameters

scene

The index for the scene manager

void AssetManager::stopAll

(

)

Stops all of the allocated scene managers.

void AssetManager::stopScene

(

int

scene

)

Stops the scene manager for the given index

Parameters

scene

The index for the scene manager
