android - 带参数的 CCCallback 的 Cocos2d-x 问题

Question

我正在尝试使用 CCSequence 为 Sprite 制作动画，我需要将参数传递给回调，但是当我这样做时我得到了

signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 00000021

这是我的代码:

void Board::createExplotion(CCPoint boardPosition){
    Mineral* mineralToAnimate = this->boardPieces[(unsigned char) boardPosition.y][(unsigned char) boardPosition.x];
    CCArray* params = CCArray::create(mineralToAnimate, NULL);

    params->retain();

    CCSequence* s1 = CCSequence::create(
                        CCScaleTo::create(0.5f, SELECTED_SCALE),
                        CCScaleTo::create(0.25f, SELECTED_SCALE + 0.1),
                        CCCallFuncO::create(this, callfuncO_selector(Board::test), params )
                        //CCCallFunc::create(this, callfunc_selector(Board::test))
                    );

        mineralToAnimate->runAction(s1);
    }

void Board::test(CCNode* sender, CCObject* data){ ... }

我在没有参数的情况下尝试了相同的代码并且它有效。

我正在使用 eclipse，但调试器并没有多大帮助，或者至少我不知道如何做，adb logcat 显示了这一点:

构建指纹:

谢谢。

如果你想用 Action 回调发送数据，那么你必须使用节点和数据选择器而不是对象选择器。因此更改行:

CCCallFuncO::create(this, callfuncO_selector(Board::test), params )

到

CCCallFuncND::create(this, callfuncND_selector(Board::test), params )
