c# - 为什么 Unity 卡在 Application.EnterPlayMode 上？

Question

我正在尝试使用 perlin 噪声和统一行进立方体创建程序地形生成器。它一直有效，直到我从创建高度图切换到将其制作成 3d 数组。然后，每当我点击播放时，unity 都会打开一个对话框，其中写着 Application.EnterPlayMode，它不会消失，也不会进入播放模式。当它发生时一切都停止响应，他们停止它的唯一方法是在任务管理器中将其杀死。

有问题的脚本如下:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Noise : MonoBehaviour
{
    //Determines whether to show debug values
    public bool debug = false;

    //Determines flatness of the terrain
    public float noiseScale = 0.5f;

    //Type of perlin noise to use
    public enum PerlinNoise {
        twoD,
        threeD
    };
    public PerlinNoise perlinNoiseDimension = PerlinNoise.twoD;

    //To return noise data after all calculations
    public float[,,] getTerrainData(int x, int y, int z)
    {
        float[,,] terrainData = new float[x, y, z];

        if(perlinNoiseDimension == PerlinNoise.twoD)
        {
            terrainData = PerlinNoise2D(x, y, z, noiseScale);
        }
        return terrainData;
    }

    //Determine noise values using 2D Perlin noise
    private float[,,] PerlinNoise2D(int x, int y, int z, float noiseScale)
    {
        float[,,] voxelHeights = new float[x, y, z];

        if (debug)
        {
            Debug.Log("Heightmap");
        }

        //Origin points to sample from
        float xOrg = Random.Range(0.0f, 0.9999999f);
        float yOrg = Random.Range(0.0f, 0.9999999f);

        for (int currentx = 0; currentx < x; currentx++)
        {
            for (int currenty = 0; currenty < y; currenty++)
            {
                //Convert Values to Fractions
                float xCoord = (float)currentx / (x * noiseScale) + xOrg;
                float yCoord = (float)currenty / (y * noiseScale) + yOrg;

                float height = Mathf.PerlinNoise(xCoord, yCoord) * z;

                for(int currentz = 0; currentz <= height; z++)
                {
                    voxelHeights[currentx, currenty, currentz] = 1;
                }

                if (debug)
                {
                    Debug.Log("Height = " + height + ", X = " + currentx + ", Y = " + currenty + ", X Coord = " + xCoord + ", Y Coord = " + yCoord);
                }
            }

        }
        return voxelHeights;
    }
}

你正在造成一个永无止境的循环

for(int currentz = 0; currentz <= height; z++)
{
    voxelHeights[currentx, currenty, currentz] = 1;
}

这里你增加了z++但是你的循环条件是 currentz <= height .在循环中，您永远不会更新 currentz 的值也不是 height 的值所以你的循环永远不会结束。

由于索引的使用，它可能更应该是

for(int currentz = 0; currentz <= height; currentz++)
{
    voxelHeights[currentx, currenty, currentz] = 1;
}

但是不确定如何height在这里发挥作用是因为我希望它看起来有点像例如

for(int currentz = 0; currentz < z; currentz++)
{
    voxelHeights[currentx, currenty, currentz] = height;
}

这对我来说似乎更有意义。
