Question

当前脚本所在的对象下的地形，该地形将达到最大高度。我可以以某种方式将其设置为指定高度的变量吗？

我没有尝试太多，因为我不知道这怎么做都很好。

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

public class test : MonoBehaviour {

    public Terrain terr; // terrain to modify
    int hmWidth; // heightmap width
    int hmHeight; // heightmap height

    int posXInTerrain; // position of the game object in terrain width (x axis)
    int posYInTerrain; // position of the game object in terrain height (z axis)

    int size = 5; // the diameter of terrain portion that will raise under the game object
    float desiredHeight = 2; // the height we want that portion of terrain to be

    void Start()
    {

        terr = Terrain.activeTerrain;
        hmWidth = terr.terrainData.heightmapWidth;
        hmHeight = terr.terrainData.heightmapHeight;

    }

    void Update()
    {

        // get the normalized position of this game object relative to the terrain
        Vector3 tempCoord = (transform.position - terr.gameObject.transform.position);
        Vector3 coord;
        coord.x = tempCoord.x / terr.terrainData.size.x;
        coord.y = tempCoord.y / terr.terrainData.size.y;
        coord.z = tempCoord.z / terr.terrainData.size.z;

        // get the position of the terrain heightmap where this game object is
        posXInTerrain = (int)(coord.x * hmWidth);
        posYInTerrain = (int)(coord.z * hmHeight);

        // we set an offset so that all the raising terrain is under this game object
        int offset = size / 2;

        // get the heights of the terrain under this game object
        float[,] heights = terr.terrainData.GetHeights(posXInTerrain - offset, posYInTerrain - offset, size, size);

        // we set each sample of the terrain in the size to the desired height
        for (int i = 0; i < size; i++)
            for (int j = 0; j < size; j++)
                heights[i, j] = desiredHeight;


        // set the new height
        terr.terrainData.SetHeights(posXInTerrain - offset, posYInTerrain - offset, heights);

    }

}

我希望有一个输入并将高度设置为输入的高度。

示例：输入= 10 物体下方的地形变为10

实际输出：输入-10 物体下方的地形达到600

您传递给SetHeights方法的高度应在0到1之间。0表示0，1表示地形的最大高度。

var heightScale = 1.0f / terr.terrainData.size.y;
for (int i = 0; i < size; i++)
    for (int j = 0; j < size; j++)
       heights[i, j] = desiredHeight * heigthScale;

在运行期间将地形设置为特定高度？
