我能够在 iPhone 模拟器上运行此代码而不会出错。但是,当我在 iPhone 上运行它时,我收到了 EXC_BAD_ACCESS 错误。这是代码:
CCAnimate * explosionAnimate = CCAnimate::create(explosionAnimation);
CCCallFuncN * callFuncN = CCCallFuncN::create(this,callfuncN_selector(GameLayer::removeChildFromParent));
CCFiniteTimeAction * explosionSequence = CCSequence::create(explosionAnimate, callFuncN);
CCSprite * explosionSprite = CCSprite::createWithSpriteFrameName("explosion_frame_1");
addChild(explosionSprite);
explosionSprite->setPosition(point);
explosionSprite->runAction(explosionSequence);
}
void GameLayer::removeChildFromParent(CCNode * child)
{
child->removeFromParent();
}
调用 CCSequence::create(...) 时会发生错误。通过 CCSequence::create(...) 调试
CCFiniteTimeAction* CCSequence::create(CCFiniteTimeAction *pAction1, va_list args)
{
CCFiniteTimeAction *pNow;
CCFiniteTimeAction *pPrev = pAction1;
while (pAction1)
{
pNow = va_arg(args, CCFiniteTimeAction*);
if (pNow)
{
pPrev = createWithTwoActions(pPrev, pNow);
}
else
{
break;
}
}
return pPrev;
}
我看到“createWithTwoActions”被调用了两次。这似乎不对。第二次调用“createWithTwoActions”。该错误发生在 CCFiniteTimeAction 中,特别是在 getDuration() 内联函数中:
inline float getDuration(void) { return m_fDuration; }
任何想法为什么会发生这种情况?
