Unity3d 我的自定义地形生成插件实例化了许多预设

问题如下：通常脚本应该在播放器周围的立方体中生成16个预制块，当我启动时，它可以正常工作，因为它调用启动时生成函数，但当我使用第一人称控制器踩下另一个块时，它每秒生成这16个块，它会造成很多延迟，而且非常容易出错，不应该生成那么多预设，非常感谢任何帮助。多谢各位

我不认为问这么大的问题是允许的，但在连续几天试图解决这个问题后，它似乎仍然不起作用。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：该脚本在玩家周围生成一个形状为 立方体。它还将这些块保存到一个

    .txt

    文件中，这样它们就可以 在需要时加载，以最小化滞后量
  • 一个名为

    chunkRename

    的脚本，附加到生成的每个区块
    脚本的简短描述：重命名块，以便在另一个脚本中轻松访问它们

以下是脚本：

首先，将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);
        }
    }

致：

最后，从代码中可以看出，您希望根据播放器当前所在的位置生成新一代。与其在OnTiggerExit中执行此操作，不如将其放入OnTiggerEnter（）中，然后将触发器对象传递给函数，这样就不需要在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);
    }
}

我找不到您要保存块的位置，但您希望这样做时只生成所需的新块。

这是否违反规则？很抱歉我会编辑它。这个代码太乱了。。我想问一下您是否听说过阵列，但后来注意到您已经在某些地方使用了它们。严肃地说：使用chunk[25]而不是25个不同的变量。

if(col.gameObject.tag == "Player") {
    this.name = "Chunk (" + this.transform.position.x + ", " + this.transform.position.y + ", " + this.transform.position.z + ")";
    col.gameObject.SendMessage("callGenerate");
}

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);
    }
}
