当一个对象被创建时，它就成为现有对象的一部分。

1

当您创建一个新对象时，它会立即成为主对象的一部分。我是 Blender 的新手，如何创建一个与现有对象无关的新对象？

(Cntrl + J)- 没有帮助。

(Shift + A)- 没有帮助。

如何在第二次单击时恢复对象的颜色（如果第一次单击时颜色发生变化并且有多个对象）？

2

问题在于重新点击，考虑到对象不是一个（因此它们的颜色不同），如何保存和恢复对象的颜色。比如两个盒子：黄色和蓝色，我们把两者的颜色都改成黑色，如何恢复它们原来的颜色呢？

using System.Collections.Generic;
using UnityEngine;

public class VisualRay : MonoBehaviour
{
    public UnityEngine.UI.Selectable CurrentSelectable;
    private Color color;
    void LateUpdate()
    {   
        Ray ray =  Camera.main.ScreenPointToRay(Input.mousePosition);
        Debug.DrawRay(transform.position, transform.forward*100f, Color.yellow);
        
        
        RaycastHit hit;
        if (Physics.Raycast(ray, out hit))
        {       

            GameObject selectable = hit.collider.gameObject;
            if ((selectable.tag == "Box") && (Input.GetKeyDown(KeyCode.F)))
            {
                color = selectable.GetComponent<Renderer>().material.color;
                selectable.GetComponent<Renderer>().material.color = Color.red;
            }
               
        }
    }
}

我试过这样，但没有奏效：

using System.Collections.Generic;
using UnityEngine;

public class VisualRay : MonoBehaviour
{
    public Transform Pointer;
    public UnityEngine.UI.Selectable CurrentSelectable;
    private Color color;
    bool Transform_color = false;
    void LateUpdate()
    {   
        Ray ray =  Camera.main.ScreenPointToRay(Input.mousePosition);
        Debug.DrawRay(transform.position, transform.forward*100f, Color.yellow);
        
        
        RaycastHit hit;
        if (Physics.Raycast(ray, out hit))
        {
            Pointer.position = hit.point;

            GameObject selectable = hit.collider.gameObject;
            if ((selectable.tag == "Box") && (Input.GetKeyDown(KeyCode.F)))
            {
                if (Transform_color == false)
                {
                    color = selectable.GetComponent<Renderer>().material.color;
                    selectable.GetComponent<Renderer>().material.color = Color.red;
                    Transform_color = true;
                }
                else
                {
                    selectable.GetComponent<Renderer>().material.color = color;
                }
            }
        }
    }
}

对象继承不能统一工作

我无法理解，在 Unity 中，随着对象的继承，以前一切似乎都是相互关联的（胶囊随着立方体一起移动），但现在它们只能在直接交互的情况下移动。

我看不懂代码：移动组件

我知道暴露一整段代码并要求解析它是不正确的，但我无法理解它是如何工作的，我浏览了 C# 教科书上的基础，部分理解它是什么样的，但是 C# for团结是非常不同的......

public class FPSInput : MonoBehaviour {
    public float speed = 6.0f;
    public float gravity = -9.8f;
    private CharacterController _charController;

    void Start() {
        _charController = GetComponent<CharacterController>();
    }

    void Update() {
        float deltaX = Input.GetAxis("Horizontal") * speed;
        float deltaZ = Input.GetAxis("Vertical") * speed;
        Vector3 movement = new Vector3(deltaX, 0, deltaZ);
        movement = Vector3.ClampMagnitude(movement, speed);
        movement.y = gravity;
        movement *= Time.deltaTime;
        movement = transform.TransformDirection(movement);
        _charController.Move(movement);
    }

解析时出现 Requests.exceptions.InvalidSchema 错误

我正在编写一个应该通过所有链接 en.wikipedia.org Category:Animals_alphabetically ( https://ru.wikipedia.org/w/index.php?title=Category:Animals_alphabetically&from=А ) 的代码，但是在网站上链接不会更改数字（.../page = 1..），并且 pagefrom=Azov+button（链接取决于页面上的第一个动物）。因此，有必要走更艰难的路。

代码算法如下：

从按钮中获取链接 # 该站点有一个“下一页”按钮。
按照链接
重复
停在最后一个链接（我自己开的）
