Summary of the use of CCSprite in cocos2d

1. Wizard creation and initialization

1. Create an image file:

[Cpp]
CCSprite * sprite = [CCSprite spriteWithFile: @ "Icon.png"];
2. Create a frame cache:

[Cpp]
[[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile: @ "MineSweeping. plist"];
CCSprite * sprite = [CCSprite spriteWithSpriteFrameName: @ "Icon.png"];
3. Initialization and Custom Size

[Cpp]
CCSprite * sprite = [CCSprite spriteWithFile: @ "Icon.png" rect: CGRectMake (x, y, w, h)];
Note: The default positioning point is ccp (0.5, 0.5). The default position is ccp () and contentSize is the size of the sprite image.

2. Common attributes and methods of genie:

[Cpp]
[Self addChild: sprite]; // In the add-in layer, self is a CCLayer
Sprite. scale = 2; // zoom in 2 times. The parameter is proportional. 1 remains unchanged. 0.5 represents 50%, and 2 represents 200%.
Sprite. rotation = 90; // Rotate 90 degrees
Sprite. opacity = 255; // sets the transparency to completely opaque (range: 0 ~ 255)
Sprite. anchorPoint = ccp (0.5); // set the anchorPoint to the lower left corner. The default value is the center point of the ccp (0.5 ,).
Sprite. position = ccp (100,100); // set the coordinates in the lower left corner of the genie to x = 100, y = 100, and local GL coordinates.
[Sprite setFlipX: YES]; // reverse the X axis Image
[Sprite setFlipY: YES]; // the Y axis image is reversed.
[Sprite setVisible: NO]; // set to hide. The default value is visible.
[Sprite setColor: ccc3 (255, 0, 0)]; // set the color to red, primary color
[Sprite zOrder]; // The sprite cascade order is the Z axis (smaller and larger). Note that this is a read-only attribute and cannot be reset through sprite. zOrder = 2.
[Sprite setTextureRect: CGRectMake (10, 10, 30, 30)]; // coordinates of the start point (for the lift coordinate system), width and height
3. Add other genie

CCSprite inherits from CCNode, so you can perform addChild operations on it:

[Cpp
CCSprite * s1 = [CCSprite spriteWithFile: @ "Icon.png"];
CCSprite * s2 = [CCSprite spriteWithFile: @ "Icon.png"];
[S1 addChild: s2];
Iv. Resetting the zaxis of the genie

[Cpp]
[Self reorderChild: sprite z: 10]; // self is CCLayer
5. Change the sprite

1. directly use the new texture for replacement
[Cpp]
// Change the texture
CCTexture2D * texture = [[CCTextureCache sharedTextureCache] addImage: @ "Default.png"]; // create a texture
[Sprite setTexture: texture];
2. Use frame replacement

[Cpp]
// Load the frame Cache
[[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile: @ "MineSweeping. plist"];
// Retrieves default.png from the frame cache.
CCSpriteFrame * frame2 = [[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName: @ "Default.png"];
[Sprite setDisplayFrame: frame2];
