Question

我正在尝试在我的Minecraft克隆中生成简单的地形。每当我尝试运行脚本时，它会将所有实例化对象放在0,0,0位置。这是我生成地形的C＃代码：

using UnityEngine;
using System.Collections;

public class TerrainGen : MonoBehaviour {

    public int radius;
    public int maxHeight;

    public GameObject block;

    void Start ()
    {
        for (float x = 0; x < radius; x+=1)
        {
            for (float z = 0; z < radius; z+=1)
            {
                float y = Random.Range(1, maxHeight);
                Vector3 v = new Vector3(x, y, z);
                GameObject newBlock = Instantiate(block, v, Quaternion.identity) as GameObject;
                Debug.Log("Block's Position: " + newBlock.transform.position + " | Wanted Position: " + v);
            }
        }
    }

    void Update ()
    {

    }

Answer 1

看起来radius尚未设置为某个值，因此您的for循环只运行一次。

由于x和z从零开始，并且它们都只运行一次，因此对象的x和z位置被设置为零。

对不起我给你所有人带来的所有麻烦。当然，我是无知的，问题不是我的地形gen脚本，而是我的块脚本！我经常设置块的位置，我非常愚蠢。谢谢！

Answer 3

Try doing this:

GameObject newBlock = Instantiate(block, v, Quaternion.identity) as GameObject;
newBlock.transform.position = v;

I don't know if this will fix your problem, and I don't know either if it's a bug with the instantiate method or if it's a misunderstanding by us, but everytime I try to instantiate an UI element, I need to reset the position (and the scale) in the same way as above. Never tried with a cube, but with UI it does the job.

Unity对象始终在0,0,0处实例化
