用循环行为一一显示 10 个单独的网格来为空游戏对象创建 "Animation"？

Question

我有 10 个网格，每个基本上都是鲸鱼游泳动画的冻结“帧”。

如果我要循环显示这些网格，那么它会创建一个伪动画，这正是我想要的。

如何实现？目前我有 GameObject AnimTest，并且我已经将 10 个网格 .obj 文件作为子文件放入其中。我已经开始在 GameObject 的脚本 changeMeshes 上使用这段代码：

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

public class changeMeshes : MonoBehaviour
{
     //Create array of the meshes
    public float[] currentMesh; 

    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        for (int i = 0; i < 10; i++)
        {
            currentMesh[i].gameObject.GetComponent<MeshRenderer>().enabled = true;
        }
    }
}

这显然是错误的，因为我是新手而且很困惑，所以我在使用像 float does not contain a definition for gameObject 这样的脚本时遇到错误。谁能帮助我走上正确的道路？

编辑：这是我更好的尝试。

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

public class changeMeshes : MonoBehaviour

{
    //Create array of the meshes
    public GameObject[] whaleMeshes;

    void FindWhales()
    {    
        whaleMeshes = GameObject.FindGameObjectsWithTag("WhaleMesh");    
        print(whaleMeshes.Length);
    }

    void CycleWhales()
    {
        for (int i = 0; i < whaleMeshes.Length; i++)
        {
            if (i > 0)
            {
                whaleMeshes[i - 1].gameObject.GetComponentInChildren<MeshRenderer>().enabled = false;
            }

            whaleMeshes[i].gameObject.GetComponentInChildren<MeshRenderer>().enabled = true;
        }
    }
    // Start is called before the first frame update
    void Start()
    {
        FindWhales();
    }

    // Update is called once per frame
    void Update()
    {
        CycleWhales();
        
    }
}

现在的结果是只有最后一个网格被永久渲染，而不是脚本循环遍历网格。如何让网格体循环？

Answer 1

嗯 .. 浮点数没有属性 .gameObject .. 甚至 Mesh 也不会

既然你说对象是这个组件的子对象，你就可以简单地遍历它们。

然后我会简单地激活和停用整个 GameObject。

听起来你想做的是

public class changeMeshes : MonoBehaviour
{
    // How long should one mesh be visible before switching to the next one
    [SerializeField] private float timePerMesh = 0.2f;

    public UnityEvent whenDone;

    private IEnumerator Start()
    {
        // Get amount of direct children of this object
        var childCount = transform.childCount;

        // Get the first child 
        var currentChild = transform.GetChild(0);

        // Iterate through all direct children
        foreach(Transform child in transform)
        {
            // Set all objects except the first child to inactive
            child.gameObject.SetActive(child == currentChild);
        }

        // Iterate though the rest of direct children
        for(var i = 1; i < childCount; i++)
        {
            // Wait for timePerMesh seconds
            yield return new WaitForSeconds(timePerMesh);

            // Set the current child to inactive
            currentChild.gameObject.SetActive(false);
            // Get the next child
            currentChild = transform.GetChild(i);

            // Set this one to active  
            currentChild.gameObject.SetActive(true);
        }

        // Optionally do something when done like e.g. destroy this GameObject etc
        yield return new WaitForSeconds(timePerMesh);

        whenDone.Invoke();
    }
}

Display 10 separate Meshes one by one with looping behavior to create "Animation" for empty GameObject?
