algorithm - Unity3d 地形生成实例化到很多预制件

我的“Update()”函数中有一段代码，用于获取场景中的事件 block ，当它找到该 block 时，它会将这些坐标传递给“generateFromMiddleOfChunk()”函数。该函数将生成玩家周围 3 半径范围内的所有 block ，它使用 25 个“Instantiate()”函数和一个公式来实现。但它只应该在还没有 block 的地方实例化 block 。它不会那样做，如果有人可以看一下我的代码，我将不胜感激。对于非常重复的代码和大量 Debug.Log() 函数，我深表歉意。非常感谢您的帮助，非常感谢。

乔迪，

我的 Update() 函数中有这段代码:

function Update() {
    var gameObjects : GameObject[] = FindObjectsOfType(GameObject) as GameObject[];
    for (var i = 0; i < gameObjects.length ; i++) {
        if(gameObjects[i].name.Substring(0,6) == "ACTIVE")
            if(gameObjects[i].tag != "Player") {
            var xco = gameObjects[i].transform.position.x;
            var yco = gameObjects[i].transform.position.y;
            var zco = gameObjects[i].transform.position.z;
            Debug.Log(xco.ToString()+yco.ToString()+zco.ToString());
            generateFromMiddleOfChunk(xco, yco, zco);
            }                   
    }
}

此代码块获取场景中的 block 并获取其 x、y 和 z 坐标，并将这些坐标传递给 generateFromMiddleOfChunk() 函数。这个函数看起来像这样:

function generateFromMiddleOfChunk(xco : int, yco : int, zco : int) {
    //V1
    chunk1 = "Chunk (" + xco.ToString() + ", " + yco.ToString() + ", " + zco.ToString() + ")";
