当我尝试运行游戏时，我目前遇到以下错误的问题。我试着理解以下错误的含义，但我发现很难理解。我相信有不止一个错误，但我不知道在哪里看。我很想得到你的帮助！

答案 0 :(得分：1)
CC_PROPERTY(int, _turnCount, TurnCount);
虚拟方法定义应该是这样的，因为在声明中它是常量。
int Character::getTurnCount() const
{
return _turnCount;
}
在getter方法的返回类型中存在问题，应该是这样的。
CC_PROPERTY(PositionIndex, _positionIndex, PositionIndex);
PositionIndex BallSprite::getPositionIndex() const
{
return _positionIndex;
}
编辑
您无法直接访问PositionIndex，请将其与BallSprite一起使用
BallSprite::PositionIndex BallSprite::getPositionIndex() const
{
return _positionIndex;
}
