C++ 游戏出错，我很确定指针有问题。但我不知道

Question

我不知道你是如何解决这个问题的。它一直告诉我没有匹配的函数可以调用，并且一直说参数 1 没有从 'Npc**' 到 'Npc*

的已知转换

具体来说，是说 handleDialogueTwo(&nonplayer); 有问题；和 handleDialogueThree(&nonplayer);

我确定这是一个愚蠢的修复程序，但我已经挠头了好几个小时了。请帮忙

void Dungeon::handleRoomWithNpc(Room * room) {
    Npc nonplayer = room->nonplayer.front();

        "a: Talk to " + nonplayer.name,
        "b: Fight " + nonplayer.name,
        "c: Leave",
        };
    while(true) {

Answer 1

数据nonplayer的类型是Npc *，被调用者的参数类型也是Npc *，所以在[=14=中不需要& ] 和 handleDialogueThree(&nonplayer);。删除它们。
