Singleton that handles the loading of the sprite frames.
The SpriteFrameCache loads SpriteFrames from a .plist file. A SpriteFrame contains information about how to use a sprite located in a sprite sheet.
The .plist file contains the following elements:
frames
: Dictionary of sprites. Key is the sprite's name, value a dict containing the sprite frame data. A sprite frame consists of the following values:spriteOffset
: difference vector between the original sprite's center and the center of the trimmed spritespriteSize
: size of the trimmed spritespriteSourceSize
: size of the original spritetextureRect
: the position of the sprite in the sprite sheettextureRotated
: true if the sprite is rotated clockwiseanchor
: anchor point in normalized coordinates (optional) Optional values when using polygon outlinestriangles
: 3 indices per triangle, pointing to vertices and verticesUV coordinatesvertices
: vertices in sprite coordinates, each vertex consists of a pair of x and y coordinatesverticesUV
: vertices in the sprite sheet, each vertex consists of a pair of x and y coordinatesmetadata
: Dictionary containing additional information about the sprite sheet:format
: plist file format, currently 3size
: size of the texture (optional)textureFileName
: name of the texture's image fileUse one of the following tools to create the .plist file and sprite sheet:
