主函数的部分代码
void HelloWorld::createCardSprite(cocos2d::CCSize size){
int lon = (size.width-28)/4;
for (int j=0; j<4; j++) {
for(int i=0;i<4;i++){
CardSprite *card = CardSprite::createCardSprite(2, lon, lon, lon*j+20, lon*i+20+size.height/6);
addChild(card);
}
}
}
调用的那个类
CardSprite* CardSprite::createCardSprite(int numbers,int wight,int height,float CardSpriteX,float CardSpriteY){
CardSprite *enemy=new CardSprite();
if(enemy && enemy->init()){
enemy->autorelease();
enemy->enemyInit(numbers, wight, height, CardSpriteX, CardSpriteY);
return enemy;
}
CC_SAFE_DELETE(enemy);
return NULL;
}
bool CardSprite::init(){
if(CCSprite::init()){
return false;
}
return true;
}
void CardSprite::setNumber(int num){
number = num;
if(number > 0){
labttfcardNumber->setString(CCString::createWithFormat("%i",number)->getCString());
}else{
labttfcardNumber->setString("");
}
}
int CardSprite::getNumber(){
return number;
}
void CardSprite::enemyInit(int numbers,int wight,int height,float CardSpriteX,float CardSpriteY){
number = numbers;
layerColorBG = CCLayerColor::create(ccc4(200, 170, 180, 255), wight-15, height-15);
layerColorBG->setPosition(CCPoint(CardSpriteX,CardSpriteY));
this->addChild(layerColorBG);
if(number > 0){
labttfcardNumber = CCLabelTTF::create(CCString::createWithFormat("%i",number)->getCString(),"Thonburi",100);
labttfcardNumber->setPosition(CCPoint(layerColorBG->getContentSize().width/2,layerColorBG->getContentSize().height/2));
layerColorBG->addChild(labttfcardNumber);
}else{
labttfcardNumber = CCLabelTTF::create("","Thonburi",100);
labttfcardNumber->setPosition(CCPoint(layerColorBG->getContentSize().width/2,layerColorBG->getContentSize().height/2));
layerColorBG->addChild(labttfcardNumber);
}
}
