为什么我会收到"void value not ignored as ought to be"错误？

首先，我想声明我正在处理一个家庭作业问题，因此，如果给出的任何答案不仅仅是答案，而是解释，我将不胜感激。另外，如果您担心帮助解决家庭作业问题，我只想让您知道我的老师鼓励我们使用此网站寻求帮助，因此您无需觉得自己在帮助我作弊！

无论如何，这是眼前的问题。我正在制作一个基于控制台的小型"游戏"，您可以在其中尝试找到从开始Location到结束Location的方式。Location头文件如下所示：

enum Direction {NORTH, SOUTH, EAST, WEST};
class Location{
string name;
bool visited;
Location* neighbors[4];
public:
Location();
Location(string locName);
string getDescription();
bool hasNeighbor(Direction dir);
Location* getNeighbor(Direction dir);
void setNeighbor(Direction dir,  Location* neighborLoc);
string getName();
void setName(string newName);
bool visit();
bool getVisited();
};

该程序的基本思想是每个Location都有四个其他可能的Location可以链接到。"游戏"的目标是让玩家从一个位置开始，在这种情况下，它是"一个深而黑暗的洞穴"，并通过穿越这些Location最终出现在地表上。

为了设置这一点，我有一个生成整个场景的函数void buildMap(Location* startLoc, Location* endLoc)。我面临的问题出现在此功能期间，我不明白问题是什么。对于带有 setNeighbor() 函数的每一行，我都收到错误"void 值未按应忽略"。我已经研究了这个错误，发现最常见的原因是当程序尝试使用函数时，就好像它返回一个值一样，但我看不出我可以在哪里这样做。这是我的函数的示例：

void buildMap(Location* startLoc, Location* endLoc){
//Initialize all of the locations on the heap with temporary pointers
startLoc = new Location("a deep, dark cave");
endLoc = new Location("the surface");
Location* passage = new Location("a musty passage");
Location* shaft = new Location("a twisting shaft");
Location* alcove = new Location("a dusty alcove");
Location* toSurface = new Location("a passage to the surface");
Location* cavern = new Location("a collapsed cavern");
Location* shore = new Location("the shores of an underground lake");
//Set up the deep, dark, cave's neighbors
*startLoc->setNeighbor(NORTH, passage);     //IDE changed my "." to a "->"? 
*startLoc->setNeighbor(EAST, shore);       
*startLoc->setNeighbor(SOUTH, cavern);
//Set up the musty passage's neighbors
*passage->setNeighbor(EAST, shaft);
*passage->setNeighbor(SOUTH, startLoc);
//Set up the twisting shaft's neighbors
*shaft->setNeighbor(EAST, alcove);
*shaft->setNeighbor(SOUTH, shore);
//Set up the dusty alcove's neighbors
*alcove->setNeighbor(SOUTH, toSurface);
//Set up the passage to the surface's neighbors
*toSurface->setNeighbor(NORTH, alcove);
*toSurface->setNeighbor(WEST, endLoc);
//Set up the collapsed cavern's neighbors
*toSurface->setNeighbor(NORTH, startLoc);
//Set up the shore's neighbors
*toSurface->setNeighbor(NORTH, shaft);
*toSurface->setNeighbor(WEST, startLoc);
}

如果有帮助，这里也是setNeighbor函数：

void Location::setNeighbor(Direction dir, Location* neighborLoc){
neighbors[dir] = neighborLoc;
}

这是我收到的错误的一个例子。它发生在具有相同错误的每个类似行上。

*startLoc->setNeighbor(NORTH, passage);  

非常感谢任何可以解决此错误的帮助，如果需要更多信息，请发表评论，以便我可以帮助您帮助我。
