Question

我想要它做的是在编辑器和运行游戏时同时看到所有球体移动到另一个方向或者它可能是相同的方向直到endPoint然后返回到startPoint中循环没有停止。

这是我的剧本：

using System;
using UnityEngine;
using Random = UnityEngine.Random;

[ExecuteInEditMode]
public class SphereBuilder : MonoBehaviour
{
    // for tracking properties change
    private Vector3 _extents;
    private int _sphereCount;
    private float _sphereSize;

    /// <summary>
    ///     How far to place spheres randomly.
    /// </summary>
    public Vector3 Extents;

    /// <summary>
    ///     How many spheres wanted.
    /// </summary>
    public int SphereCount;

    public float SphereSize;

    private void OnValidate()
    {
        // prevent wrong values to be entered
        Extents = new Vector3(Mathf.Max(0.0f, Extents.x), Mathf.Max(0.0f, Extents.y), Mathf.Max(0.0f, Extents.z));
        SphereCount = Mathf.Max(0, SphereCount);
        SphereSize = Mathf.Max(0.0f, SphereSize);
    }

    private void Reset()
    {
        Extents = new Vector3(250.0f, 20.0f, 250.0f);
        SphereCount = 100;
        SphereSize = 20.0f;
    }

    private void Update()
    {
        UpdateSpheres();
    }

    private void UpdateSpheres()
    {
        if (Extents == _extents && SphereCount == _sphereCount && Mathf.Approximately(SphereSize, _sphereSize))
            return;

        // cleanup
        var spheres = GameObject.FindGameObjectsWithTag("Sphere");
        foreach (var t in spheres)
        {
            if (Application.isEditor)
            {
                DestroyImmediate (t);
            }
            else
            {
                Destroy(t);
            }
        }

        var withTag = GameObject.FindWithTag("Terrain");
        if (withTag == null)
            throw new InvalidOperationException("Terrain not found");

        for (var i = 0; i < SphereCount; i++)
        {
            var o = GameObject.CreatePrimitive(PrimitiveType.Sphere);
            o.tag = "Sphere";
            o.transform.localScale = new Vector3(SphereSize, SphereSize, SphereSize);

            // get random position
            var x = Random.Range(-Extents.x, Extents.x);
            var y = Extents.y; // sphere altitude relative to terrain below
            var z = Random.Range(-Extents.z, Extents.z);

            // now send a ray down terrain to adjust Y according terrain below
            var height = 10000.0f; // should be higher than highest terrain altitude
            var origin = new Vector3(x, height, z);
            var ray = new Ray(origin, Vector3.down);
            RaycastHit hit;
            var maxDistance = 20000.0f;
            var nameToLayer = LayerMask.NameToLayer("Terrain");
            var layerMask = 1 << nameToLayer;
            if (Physics.Raycast(ray, out hit, maxDistance, layerMask))
            {
                var distance = hit.distance;
                y = height - distance + y; // adjust
            }
            else
            {
                Debug.LogWarning("Terrain not hit, using default height !");
            }

            // place !
            o.transform.position = new Vector3(x, y, z);
        }

        _extents = Extents;
        _sphereCount = SphereCount;
        _sphereSize = SphereSize;
    }
}

更新

我创建了另一个c＃脚本并将其拖到地形。

using UnityEngine;
using System.Collections;

public class MoveSpheres : MonoBehaviour {

    public Transform _transform;
    private Vector3 pos1 = new Vector3(-4,0,0);
    private Vector3 pos2 = new Vector3(4,0,0);
    public float speed = 1.0f;
    // Use this for initialization
    void Start () {



    }

    // Update is called once per frame
    void Update () {

        _transform.position = Vector3.Lerp (pos1, pos2, Mathf.PingPong(Time.time*speed, 1.0f));


    }
}

此脚本移动一个Sphere。但我想移动所有的球体。而且，如果我在第一个脚本中更改了Spheres的数量，那么移动它们也继续移动它们。

问题在于第一个脚本中的Destroy部分。

你可以将球体从一个位置变为另一个位置并返回https://docs.unity3d.com/ScriptReference/Vector3.Lerp.html

如何将地形上的所有球体从其原始位置移动到新位置并回到原始环路中？
