cocos2d-x – 更改播放器动画时出错

首先,我使用的是cocos2d 3.6
一切顺利,直到我按下键盘上的右箭头键,从keypress事件监听器执行startRunning()函数,操作成功停止,但在下一行,this-> runAction(Animate :: create(runAnimation));,得到错误.
runAnimation是OK.我想问题是在运行新的Action但我不知道它是什么.

这是代码：

#pragma once

#include "cocos2d.h"

using namespace cocos2d;

const int DIR_RIGHT = 1;
const int DIR_LEFT = -1;




class CPlayer: public Sprite
{

    SpriteFrame* fallFrame;
    SpriteFrame* wallJumpFrame;

    boolean onGround = true;
    boolean running = false;
    int dir = DIR_RIGHT;
    float movementSpeed = 50; //50 unit in world space 
    float stateTime=0;

        do
        {
            sprintf(str,format,frameIndex);

            auto frame = SpriteFrameCache::getInstance()->getSpriteFrameByName(str);

            frameIndex++;
        } while (true);

            loops = -1;
