Common API Introduction

Animationcache class

Added to the cache by name and animation.
void Addanimation (Animation *animation, const std::string &name)

Add an animation from the plist file to make sure that the Spriteframecache frame has been loaded before .
void Addanimationswithfile (const std::string &plist)

Returns an animation that was previously added. If it is not found, it will return null.
Animation * getanimation (const std::string &name)

Deletes an animation from the cache.
void Removeanimation (const std::string &name)

Clears the cache, which releases all animated objects and shared instances.
static void Destroyinstance ()

Spriteframecache class

Adding multiple spriteframe from a plist file automatically loads the corresponding texture. When a texture file is not specified in the plist file, the extension of the plist file is replaced with a. png name for the texture file.
void Addspriteframeswithfile (const std::string &plist)

Loads a spriteframe with a texture file using the specified plist file.
void Addspriteframeswithfile (const std::string& plist,const std::string& texturefilename)

Add a spriteframe and specify its name.
void Addspriteframe (Spriteframe *frame, const std::string &framename)

Gets the spriteframe of the specified name.
Spriteframe * Getspriteframebyname (const std::string &name)

Check if a plist file has been loaded.
BOOL Isspriteframeswithfileloaded (const std::string &plist) const

Cleans up the loaded spriteframe.
void Removespriteframes ()

Removes a spriteframe from the cache based on the specified name.
void Removespriteframebyname (const std::string &name)

Frees unused spriteframe. Spriteframe with a reference count of 1 will be deleted. When entering a new scene, you can easily release the spriteframe that you no longer use by calling this method.
void Removeunusedspriteframes ()

Removes the spriteframe from the cache in the specified plist file
void Removespriteframesfromfile (const std::string &plist)

Destroys an instance of Spriteframecache. All instances of Spriteframe and retain are released.
static void Destroyinstance ()
