【中文标题】我的自定义地形生成插件实例化了很多预制件【英文标题】：My custom terrain generation plugin instantiates to much prefabs 【发布时间】：2014-07-21 19:02:07 【问题描述】：问题如下：通常脚本应该在播放器周围的立方体中生成 16 个预制件，当我启动它时它工作正常，因为它调用了 generate on start 函数，但是当我用第一个人踩到另一个块时控制器它每秒生成这 16 个块，它会产生很多滞后并且确实存在故障，并且不应该生成那么多预制件，非常感谢任何帮助。非常感谢。
我不认为问这么大的问题是允许的，但是在连续几天尝试解决这个问题之后，它似乎仍然没有工作。所以这就是我得到的：
第一人称控制器 2 个脚本 一个名为infiniteTerrain 的脚本附加到第一人称控制器脚本的简短描述：此脚本生成围绕玩家的预制件，形状为
立方体。它还将这些块保存到.txt 文件中，以便它们可以
在需要时加载以最大程度地减少延迟。
一个名为 chunkRename 的脚本附加到生成的每个块脚本的简短描述：重命名这些块，以便可以在另一个脚本中轻松访问它们。
以下是脚本：

【问题讨论】：
是否违反规定？对不起，我会编辑它。 这段代码一团糟。我想问你是否听说过数组，但后来注意到你已经在某些地方使用它们了。说真的：使用 chunk[25] 而不是 25 个不同的变量。 【参考方案1】：首先，将您的 25 行实例化更改为：
for (int i = -2; i< 3; i++)
for (int j = -2; j < 3; j++)
Instantiate(terrains[Random.Range(0,terrains.length)],
Vector3(j*50, 0, i*50), Quaternion.identity);
其次，你在这个调用中已经有了游戏对象，所以不要使用 GameObject.Find() //它很昂贵 因此，假设标记为“播放器”的对象具有 FPS 控制器，请更改：
if(col.gameObject.tag == "Player")
this.name = "Chunk (" + this.transform.position.x + ", " + this.transform.position.y + ", " + this.transform.position.z + ")";
gameObject.Find("First Person Controller").SendMessage("callGenerate");
收件人：
if(col.gameObject.tag == "Player")
this.name = "Chunk (" + this.transform.position.x + ", " + this.transform.position.y + ", " + this.transform.position.z + ")";
col.gameObject.SendMessage("callGenerate");
最后，从您的代码看来，您希望根据玩家当前所在的位置生成您的一代。与其在 OnTriggerExit 中执行此操作，不如将其放在 OnTriggerEnter() 中，然后将触发器对象传递给您的函数，这样您就无需在 callGenerate 方法中查找活动对象：
function OnTriggerEnter (col : Collider)
if(col.gameObject.tag == "Player")
this.name = "ACTIVE_Chunk (" + this.transform.position.x + ", " + this.transform.position.y + ", " + this.transform.position.z + ")";
col.gameObject.SendMessage("callGenerate", this.gameObject);
function callGenerate(go: GameObject)
if(canGenerate)
canGenerate = false; //you were redeclaring this variable here,
//which is mostly likely why you had more generation going on than desired
generateFromMiddleOfChunk(go.transform.position);
我找不到您保存块的位置，但您希望以只生成所需的新块的方式执行此操作。
