旋转的轮盘

​ 一页 PPT 就是一个 Scene，设置一个 DontDestroyOnLoad(gameObject); 的场景切换器来切换场景。

​ 用 Animation 组件控制的会旋转的轮盘。

创建随机数

• Update() 里切换的时钟
• 仿照课本，用 randSeed、multiplier、adder、n 创建随机数。

A* 算法

这玩意当时还写了博客：Unity-Unity中的网格系统及AStar算法-Zi-Zi's Journey

布局

​ 从 主页 - Chess.com 抄的素材和配色。其实这个 PPT 没有上去讲，就当练手了。

​ 背景颜色是 #312E2B。

场景逻辑

​ 随便整了 Test 类控制所有逻辑，咱就是一个敏捷开发。

• 切换场景，只有一个场景，一个 Prefab 表示一页 PPT。不仅用鼠标，键盘 A 和 D 也可翻页。
• 可以使用三种算法：
  • Dijkstra
  • A*
  • BFS
• 两种棋子代表：8 方向和 4 方向。Z 键切换。

模糊聚类分析法

​ 老田不想上课让我们上去讲，我上去讲一讲练练手。

​ 这个时候已经有 ChatGPT 了，确实很提高效率，但是要讲的东西太复杂了，写了整整两天orz。

场景逻辑

​ 同样的场景切换逻辑，只有一个 Scene，一个 Prefab 代表一页 PPT。

​ 修改了鼠标指针。

​ 使用 Dotween 设计了场景切换的动画效果，但是好像路子有点野，有空再学吧！

模糊 ISODATA 算法

​ 这块计算量太大了，而且比较复杂，我没咋理解，更不会可视化了……

​ 用 ChatGPT 帮忙写了一个 Python 版本的，用 Jupyter Notebook 确实能跑，但是稍微改一点参数就不能跑了，不过老田估计也不懂就鬼混过去了嘻嘻嘻。

​ 把之前的代码滚动框抄了回去。

​ 布局是左边文字右边图片。配色方案：

• 背景：#312E2B
• 文字：
  • 绿：#92E86C
  • 红：#FF8080
  • 青：00FFFF

​ 写了个更换鼠标指针的逻辑，结果编译完没生效，寄！

using UnityEngine;

public class ChangeCursor : MonoBehaviour
{
    public Texture2D cursorTexture;
    // Start is called before the first frame update
    void Start()
    {
        Cursor.SetCursor(cursorTexture, Vector2.zero, CursorMode.Auto);
    }
}

​ Hierarchy 和 Project 的放置。左边的幻灯片序号是连续的，右边则不然，右边的 GameObject 绑定了 SceneID 类以和左边绑定。

using UnityEngine;

public class SceneID : MonoBehaviour
{
    public int ID = 0;
}

​ 写了个 ScenesController 类用于控制翻页。

• 按下 左/A 键向前翻页，执行 privousScene()。
• 按下 右/D 键向后翻页，执行 nextScene()。
• playAnimation() 掌管翻页动画，使用 Dotween 插件。

​ 显示图片的动画代码，这个应该是弃案了。

using System.Collections;
using System.Collections.Generic;
using System.Linq;
using UnityEngine;
using UnityEngine.UI;
using DG.Tweening;

public class ShowPictures : MonoBehaviour
{
    [SerializeField] private Transform imagesParent;
    private List<Image> images = new List<Image>();
    // Start is called before the first frame update
    void Start()
    {
        for (int i = 0; i < imagesParent.childCount; i++)
        {
            images.Add(imagesParent.GetChild(i).GetComponent<Image>());
            images[i].color = new Color(images[i].color[0], images[i].color[1], images[i].color[2], 0);
        }
        showPictures(0);
    }

    private void showPictures(int i)
    {
        if (i < images.Count)
        {
            Tweener tweener = images[i].DOFade(1, 0.5f);
            tweener.OnComplete(()=> showPictures(i + 1));
        }
        
    }
}

​ 经典的挂伟哥动画代码：

using UnityEngine;
using UnityEngine.UI;
using DG.Tweening;
using Unity.VisualScripting;

public class ChangeColor : MonoBehaviour
{
    [SerializeField] private bool isImage = true;
    private Image image;
    private Text text;
    // Start is called before the first frame update
    void Start()
    {
        if (isImage)
        {
            image = GetComponent<Image>();
            float H, S, V;
            Color.RGBToHSV(image.color, out H, out S, out V);
            changeColor(H, S, V);
        }
        else
        {
            text = GetComponent<Text>();
            float H, S, V;
            Color.RGBToHSV(text.color, out H, out S, out V);
            changeColor(H, S, V);
        }
    }

    private void changeColor(float H, float S, float V)
    {
        float newH = H + 0.01f;
        if (newH > 1)
        {
            newH = 0;
        }
        Tweener tweener = null;
        if (isImage)
        {
            tweener = image.DOColor(Color.HSVToRGB(newH, S, V), 0.05f);
        }
        else
        {
            tweener = text.DOColor(Color.HSVToRGB(newH, S, V), 0.05f);
        }
        // 将HSV颜色转换回RGB格式
        tweener.OnComplete(()=> changeColor(newH, S, V));
    }
}

​ 本来有一个按下按钮出一个闽南语祝伟哥生日快乐的功能，结果汇报的时候不知道为啥没按出来……

using UnityEngine;
using UnityEngine.UI;

public class PlaySounds : MonoBehaviour
{
    public AudioClip soundClip;
    private AudioSource audioSource;

    private void Start()
    {
        // 获取按钮所附加的 AudioSource 组件
        audioSource = GetComponent<AudioSource>();
        if (audioSource == null)
        {
            // 如果按钮上没有 AudioSource，则添加一个
            audioSource = gameObject.AddComponent<AudioSource>();
        }

        // 设置 AudioSource 的音频剪辑
        audioSource.clip = soundClip;

        // 确保按钮有一个按钮点击事件处理程序，并将 PlaySound() 方法添加为响应方法
        Button button = GetComponent<Button>();
        button.onClick.AddListener(PlaySound);
    }

    // 播放声音的方法
    private void PlaySound()
    {
        Debug.Log("Play Sound!");
        audioSource.Play();
    }
}
