hello.
I’m trying to create an explosion effect.
I have an animation, and I play the animation with a sprite. once the animation is finished, I remove the sprite from the scene:
here is how I create the action:
@
cocos2d::CCCallFunc * callFunc = cocos2d::CCCallFunc::create( effectSprite, callfunc_selector( GameScene::explosionAnimationFinished ) );
cocos2d::CCLog(“ex create: x", effectSprite);
effectSprite->runAction(cocos2d::CCSequence::create( theAnim, callFunc, NULL ) );
@
this is the callback function:
@
void GameScene::explosionAnimationFinished(cocos2d::CCObject * p_Sender)
{
cocos2d::CCNode *sprite = (cocos2d::CCNode*)p_Sender;
cocos2d::CCLog("ex read: x”, p_Sender);
sprite->removeFromParentAndCleanup(true);
}
@
this code works well under debug mode, but crash in release mode due to BAD_ACCESS
I debugged this a little bit, it turned out that the p_Sender of the callback function is an invalide pointer in the release mode.
it seems that when calling the call back function, CCCallFunc doesn’t pass in the sender:
@
void CCCallFunc::execute() {
if (m_pCallFunc) {
(m_pSelectorTarget->*m_pCallFunc)(); //sender is not passed in here
}
…
}
@
I changed (m_pSelectorTarget->*m_pCallFunc)(); to (m_pSelectorTarget->*m_pCallFunc)((CCNode*)m_pSelectorTarget);
and it worked.
is this a bug?
