Objective:

The Sprite class is a Sprite class. Its subclasses have physicssprite and skins.

Physicssprite is the physics engine Elf class, and the skin is an elf class for skeletal animation.

Creating a Sprite Elf Object

There are several ways to create a Sprite object, and the usual functions are as follows:

1) Create a Sprite object, texture and other attributes need to be set after creation

Static  sprite*  Create ();

2) Specify Image creation wizard

Static  sprite*  Create (const  std::string&  filename);

3) Specify the picture and the cropped rectangular area to create the sprite

Static  sprite*  Create (const  std::string&  filename,  const  rect&  Rect);

4) Specify texture creation Sprite

Static  sprite*  createwithtexture (texture2d*  texture);

5) Specify the texture and clipping rectangle area to create the sprite, the 3rd parameter specifies whether to rotate the texture, and does not rotate by default

Static  sprite*  createwithtexture (texture2d*  texture, const  rect&  Rect,  bool  rotated = false);

6) Create another Sprite object from one Sprite frame object

Static  sprite*  createwithspriteframe (spriteframe*  pspriteframe);

7) Create a Sprite object by specifying the sprite frame name in the frame cache

Static  sprite*  createwithspriteframename (cosnt  std::string & Spriteframename);

code example:

1Auto SPBK = Sprite::create ("Background.png");2     ////position is not set here, the default location is the lower left corner3     //spbk->setposition (Point (origin.x + VISIBLESIZE.WIDTH/2, ORIGIN.Y + visiblesize.height/2));4Spbk->Setanchorpoint (Point::zero);5      This->addchild (SPBK,0);6 7     ////Use a Texture object (texture2d) to create a Sprite object.8     ///Rect (float x, float y, float width, float height);9     //The parameter rect is an area of the Tree1.png picture, the UI coordinate system, the (604,38) coordinate position, the width 302, and the height 295TenAuto Tree1 = Sprite::create ("Tree1.png", Rect (604, -,302,295)); OneTree1->setposition (Point ( $, the)); A      This->addchild (Tree1,0); -  -texture2d* cache =director::getinstance ()->gettexturecache ( )->addimage ("Tree1.png"); theAuto Tree2 =sprite::create (); -Tree2->settexture (cache); -     //The parameter rect is an area of the Tree1.png picture, the UI coordinate system, the (73,72) coordinate position, the width 182, and the height 270 -Tree2->settexturerect (Rect ( the, the,182, the)); +Tree2->setposition (Point ( -, $)); -      This->addchild (Tree2,0);

The Texturecache instance can be obtained through the Director::getinstance ()->gettexturecache () function , Texturecache addimage (" Tree1.png ") function to create a texture texture2d object, where Tree1.png is the name of the texture picture.
