Detailed Description

A SpriteFrame has:

• texture: A Texture2D that will be used by the Sprite
• rectangle: A rectangle of the texture

You can modify the frame of a Sprite by doing:

SpriteFrame* frame = SpriteFrame::createWithTexture(texture, rect);
sprite->setSpriteFrame(frame);

Member Function Documentation

create() [1/2]

SpriteFrame * create ( std::string_view filename, const Rect & rect )

static

Create a SpriteFrame with a texture filename, rect in points.

It is assumed that the frame was not trimmed.

Parameters

filename	Texture file name.
rect	A specified rect.

Returns

An autoreleased SpriteFrame object.

create() [2/2]

SpriteFrame * create ( std::string_view filename, const Rect & rect, bool rotated, const Vec2 & offset, const Vec2 & originalSize )

static

Create a SpriteFrame with a texture filename, rect, rotated, offset and originalSize in pixels.

The originalSize is the size in pixels of the frame before being trimmed.

Parameters

filename	Texture filename
rect	A specified rect.
rotated	Is rotated if true.
offset	A specified offset.
originalSize	A specified original size.

Returns

An autoreleased SpriteFrame object.

createWithTexture() [1/2]

SpriteFrame * createWithTexture ( Texture2D * pobTexture, const Rect & rect )

static

Create a SpriteFrame with a texture, rect in points.

It is assumed that the frame was not trimmed.

Parameters

pobTexture	The texture pointer.
rect	A specified rect.

Returns

An autoreleased SpriteFrame object.

createWithTexture() [2/2]

SpriteFrame * createWithTexture ( Texture2D * pobTexture, const Rect & rect, bool rotated, const Vec2 & offset, const Vec2 & originalSize )

static

Create a SpriteFrame with a texture, rect, rotated, offset and originalSize in pixels.

The originalSize is the size in points of the frame before being trimmed.

Parameters

pobTexture	The texture pointer.
rect	A specified rect.
rotated	Is rotated if true.
offset	A specified offset.
originalSize	A specified original size.

Returns

An autoreleased SpriteFrame object.

getRectInPixels()

const Rect & getRectInPixels ( ) const

inline

Get rect of the sprite frame.

Returns

The rect of the sprite frame, in pixels.

setRectInPixels()

void setRectInPixels

(

const Rect &

rectInPixels

)

Set rect of the sprite frame.

Parameters

rectInPixels

The rect of the sprite frame, in pixels.

isRotated()

bool isRotated ( ) const

inline

Is the sprite frame rotated or not.

Returns

Is rotated if true.

setRotated()

void setRotated ( bool rotated )

inline

Set rotated of the sprite frame.

Parameters

rotated

Rotated the sprite frame if true.

getRect()

const Rect & getRect ( ) const

inline

Get rect of the frame.

Returns

The rect of the sprite frame.

setRect()

void setRect

(

const Rect &

rect

)

Set rect of the frame.

Parameters

rect	The rect of the sprite.

getCenterRect()

const Rect & getCenterRect ( ) const

inline

Get center rect of the frame.

Useful to create 9-slice sprites

Returns

The center rect of the sprite frame in points

setCenterRectInPixels()

void setCenterRectInPixels

(

const Rect &

centerRect

)

setCenterRect

Useful to implement "9 sliced" sprites. The sprite will be sliced into a 3 x 3 grid. The four corners of this grid are applied without performing any scaling. The upper- and lower-middle parts are scaled horizontally, and the left- and right-middle parts are scaled vertically. The center is scaled in both directions. Important: The scaling is based the Sprite's trimmed size.

Limitations: Does not work when the sprite is part of SpriteBatchNode.

Parameters

centerRect

the Rect in points

hasCenterRect()

bool hasCenterRect

(

)

const

hasCenterRect

Returns

Whether or not it has a centerRect

(

const Vec2 &

offsetInPixels

)

Set offset of the frame.

Parameters

offsetInPixels

The offset of the sprite frame, in pixels.
