Question

我正在尝试使用Cocos2d-x制作类似MegaMan的游戏并试图让它在Android设备上运行。问题是，我可以单独按下按钮，没有任何问题，但当我左/右跑并按下跳跃时，播放器停止移动。

当我手动设置right = true并且jump = true时，玩家会向右侧跳转，所以if else的东西执行得很好。

这是我在init（）

中所做的

        //add controls
    buttonLeft = CCMenuItemImage::create(
        "button_left.png", 
        "button_left.png");
    buttonLeft->setPosition( ccp(buttonLeft->getContentSize().width/2, buttonLeft->getContentSize().height/2) );

    buttonRight = CCMenuItemImage::create(
        "button_right.png", 
        "button_right.png");
    buttonRight->setPosition( ccp(buttonRight->getContentSize().width/2 + buttonLeft->getContentSize().width, buttonRight->getContentSize().height/2) );
    CCMenu* controlMenu1 = CCMenu::create(buttonLeft, buttonRight, NULL);
    controlMenu1->setPosition(CCPointZero);
    this->addChild(controlMenu1, 1);

    buttonJump = CCMenuItemImage::create(
        "button_jump.png", 
        "button_jump.png");
    buttonJump->setPosition(ccp(winSize.width - buttonJump->getContentSize().width/2, buttonJump->getContentSize().height/2));
    CCMenu* controlMenu2 = CCMenu::create(buttonJump, NULL);
    controlMenu2->setPosition(CCPointZero);
    this->addChild(controlMenu2, 1);

我每0.02秒安排一次：

void BeginScene::updatePlayerMove(float dt)

        playerMoveAction = NULL;
    }

    if(playerJumpAction != NULL){
        player->stopAction(playerJumpAction);
        playerJumpAction = NULL;
    }


    if(buttonLeft->isSelected()){
        player->setTexture(CCTextureCache::sharedTextureCache()->addImage("player2.png"));
        minXpos = player->getContentSize().height/2;
        newXpos = player->getPosition().x - PIXELS_PLAYER_MOVES;

        if(newXpos < minXpos){

它似乎只是在我的旧LG上工作，但在我的Galaxy s2和平板电脑上完美运行......

所以可能我的LG太老了：P

多点触控不起作用
