构造及析构函数说明

~TextureAsync()

TextureAsync::~TextureAsync ( )

virtual

在文件 Texture2dTest.cpp 第 1504 行定义.

{
    auto textureCache = Director::getInstance()->getTextureCache();
    textureCache->unbindAllImageAsync();
    textureCache->removeAllTextures();
}

成员函数说明

CREATE_FUNC()

TextureAsync::CREATE_FUNC

(

TextureAsync

)

getDuration()

virtual float TextureAsync::getDuration ( ) const

inlineoverridevirtual

Returns the time the test case needs.

重载 TestCase .

在文件 Texture2dTest.h 第 410 行定义.

{ return 5.0f; }

imageLoaded()

void TextureAsync::imageLoaded

(

cocos2d::Texture2D *

texture

)

在文件 Texture2dTest.cpp 第 1530 行定义.

{
    auto director = Director::getInstance();
 
    //CCASSERT( [NSThread currentThread] == [director runningThread], @"FAIL. Callback should be on cocos2d thread");
 
    // IMPORTANT: The order on the callback is not guaranteed. Don't depend on the callback
 
    // This test just creates a sprite based on the Texture
 
    auto sprite = Sprite::createWithTexture(texture);
    sprite->setAnchorPoint(Vec2(0,0));
    addChild(sprite, -1);
 
    auto size = director->getWinSize();
    int i = _imageOffset * 32;
    sprite->setPosition(Vec2( i % (int)size.width, (i / (int)size.width) * 32 ));
 
    _imageOffset++;
 
    log("Image loaded: %p", texture);
}

{
    auto textureCache = Director::getInstance()->getTextureCache();
    for( int i=0;i < 8;i++) {
        for( int j=0;j < 8; j++) {
            char szSpriteName[100] = {0};
            sprintf(szSpriteName, "Images/sprites_test/sprite-%d-%d.png", i, j);
            textureCache->addImageAsync(szSpriteName, CC_CALLBACK_1(TextureAsync::imageLoaded, this));
        }
    }
 
    textureCache->addImageAsync("Images/background1.jpg", CC_CALLBACK_1(TextureAsync::imageLoaded, this));
    textureCache->addImageAsync("Images/background2.jpg", CC_CALLBACK_1(TextureAsync::imageLoaded, this));

onEnter()

void TextureAsync::onEnter ( )

overridevirtual

重载 TextureDemo .

在文件 Texture2dTest.cpp 第 1484 行定义.

{
    TextureDemo::onEnter();
 
    _imageOffset = 0;
 
    auto size = Director::getInstance()->getWinSize();
 
    auto label = Label::createWithTTF("Loading...", "fonts/Marker Felt.ttf", 32);
    label->setPosition(Vec2( size.width/2, size.height/2));
    addChild(label, 10);
 
    auto scale = ScaleBy::create(0.3f, 2);
    auto scale_back = scale->reverse();
    auto seq = Sequence::create(scale, scale_back, nullptr);
    label->runAction(RepeatForever::create(seq));
 
    scheduleOnce(CC_SCHEDULE_SELECTOR(TextureAsync::loadImages), 1.0f);
