Question

今天我有一个困扰我几个小时的问题。我在youtube上看了一个关于磁场的教程，我发现了它并且我遇到了问题。在那个实现中，我必须制作一个将被吸引的对象和另一个将吸引的对象。被吸引的那个我必须创建一个空的游戏对象并给它一个碰撞器，其中写入是触发器。现在的问题是我有一个健康脚本，所以当玩家用他的身体接触任何物体时他会失去健康。这个球体对撞机是玩家的一部分，每当它接触到身体时，玩家就会失去健康。我需要帮助，因为球体对撞机有一个非常大的半径，每当它碰到游戏对象时，玩家就会失去健康。我需要球体对撞机，当它触及游戏对象时，不要让玩家失去健康，请帮忙！

所以这看起来似乎搞乱了。首先，我会建议你阅读here和here的答案，以了解你游戏中发生的事情。

现在让我们根据您在问题中分享的信息尝试解决问题。我假设磁体对象（由于大球体而被吸引）具有标记“磁铁”，因此当您的球对撞机与其碰撞时，OnTriggerEnter()方法中的以下代码会降低健康状况：

if(col.gameObject.tag == "Magnet")
{
    cur_Health -= 1f;
    float calc_Health = cur_Health / max_Health;
    SetBar (calc_Health);
}

如果您在拾取磁铁对象时不想降低健康状况，请删除此代码。

现在谈谈这部分问题：

现在问题是我有一个健康脚本所以当玩家用他的身体接触任何物体他会失去健康

当刚体连接到父对象时，触发器是由所有子对撞机引起的。所以要解决这个问题：

从Tags and Layers添加一个新图层，并将其命名为“Magnet”。
现在转到Physics Manager并配置“图层碰撞矩阵”，将磁铁图层设置为仅可碰撞到自身：

现在将此图层设置为球体对象（播放器的子对象）和触发磁场效果的磁体对象。

希望这能解决您的问题。
