1. Create a wizard from the file:

Ccsprite s = [Ccsprite spritewithfile:@ "Pic.png"];

[s SETPOSITION:CCP (20,20)];//Note that this is the Cartesian coordinates, starting from the lower left corner

S.anchorpoint = CCP (0.5f,0);//anchorpoint can be understood as a fixed point of white paper

[s.setscale:1.5f];

[Self.addchild:s z:2 Tag: "Demo"];

2. Sprite frame, loading spritesheets:

[[Ccspriteframecache Sharespriteframecache] addspriteframewithfile:@ "pic.plist"];//read the source code can be seen, most of it is the resolution plist frame, Meta will be stored in a dictionary.

Ccsprite s = [Ccsprite spritewithspriteframename:@ "Pic.png"];//pic.png to correspond to the real name field in Pic.plist.

3. Batch wizard, improve the performance of the method:

Ccspritebatchnode *SBN = [Ccspritebatchnode batchnodewithfile:@ "Sbn.png" capacity:10];

[SELF.ADDCHILD:SBN];

for (int x = 0; x < 10;x++) {

Ccsprite s = [Ccsprite spritewithbatchnode:sbn rect:cgrectmake (0,0,64,64)];

[SBN Addchild:s]

}
