任何帮助都将不胜感激。
回答：
在你的方法Fletcher_getClosestBotStrategy::pickTarget()中，你无法访问Fletcher_TargetingSystem::Update()中的变量curBot和SensedBot，因为它们是局部变量。
因此，如果你确实需要访问它们，将它们转换为Fletcher_TargetingSystem类的属性，创建setter和getter方法，并尽量避免使用friend类，重新定义你的类依赖关系：将Fletcher_TargetingSystem的常量引用传递给你的Fletcher_getClosestBotStrategy方法：
例如：
class Fletcher_getClosestBotStrategy{ void pickTarget(const Fletcher_TargetingSystem & targeting); ....};....class Fletcher_TargetingSystem { protected: std::list<AbstRaven_Bot*> SensedBots; public: std::list<AbstRaven_Bot*> & getSensedBots() const { return SensedBots; }};void Fletcher_getClosestBotStrategy::pickTarget(const Fletcher_TargetingSystem & targeting){ double ClosestDistSoFar = MaxDouble; std::list<AbstRaven_Bot*> & myLocalSensedBots = targeting.getSensedBots(); ...}
