接下来添加攻击按钮用于执行攻击动作。
同时修复了上一版移动时的bug。
修复后的Player::walkTo()函数：
void Player::walkTo(Vec2 dest)
{
if (_seq)
this->stopAction(_seq);
auto curPos = this->getPosition();
if (curPos.x > dest.x)
this->setFlippedX(true);
else
this->setFlippedX(false);
auto diff = dest - curPos;
auto time = diff.getLength() / _speed;
auto moveTo = MoveTo::create(time, dest);
auto func = [&]()
{
this->stopAllActions();
this->playAnimationForever("stay");
_seq = nullptr;
};
auto callback = CallFunc::create(func);
this->stopAllActions();
this->playAnimationForever("walk");
_seq = Sequence::create(moveTo, callback, nullptr);
this->runAction(_seq);
}
在MainScene::init()函数中添加了攻击按钮：
auto attackItem = MenuItemImage::create(
"CloseNormal.png",
"CloseSelected.png",
CC_CALLBACK_1(MainScene::attackCallback, this));
attackItem->setPosition(Vec2(origin.x + visibleSize.width - attackItem->getContentSize().width/2 ,
origin.y + attackItem->getContentSize().height/2));
// create menu, it‘s an autorelease object
auto menu = Menu::create(attackItem, NULL);
menu->setPosition(Vec2::ZERO);
this->addChild(menu, 1);
增加了攻击的回调函数：
void MainScene::attackCallback(Ref* pSender)
{
_hero->stopAllActions();
_hero->playAnimation("attack");
}
增加了Player::playAnimation()函数，执行了一次动作之后又回返回重复执行"stay"。
void Player::playAnimation(std::string animationName)
{
auto str = String::createWithFormat("%s-%s", _name.c_str(), animationName.c_str())->getCString();
bool exist = false;
for (int i = 0; i < _animationNum; i ++) {
if (animationName == _animationNames[i])
{
exist = true;
break;
}
}
if (exist == false)
return;
auto animation = AnimationCache::getInstance()->getAnimation(str);
auto func = [&]()
{
this->stopAllActions();
this->playAnimationForever("stay");
_seq = nullptr;
};
auto callback = CallFunc::create(func);
auto animate = Sequence::create(Animate::create(animation), callback,NULL);
this->runAction(animate);
}
