Question

我正在尝试从单个阵列中生成两个随机颜色，这些颜色应该是相同的。其中一种颜色是标签的bg颜色，另一种颜色是文本顶部的文本颜色。但奇怪的是我失败了。这是代码：

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

public class ColorText : MonoBehaviour {
public GUISkin mySkin;
public GameObject obj;
private Color clr;
private Color txtClr;
private string clrName;

Color[] colorList = new Color[13]{
    new Color(0,0,255,255), // mavi
    new Color(165,42,42,255), // kahverengi
    new Color(192,192,192,255), // gri (192,192,192 gümüş)
    new Color(0,128,0,255), // yeşil
    new Color(128,0,0,255), // bordo
    new Color(255,165,0,255), // turuncu
    new Color(255,192,203,255), // pembe
    new Color(128,0,128,255), // mor
    new Color(255,0,0,255), // kırmızı
    new Color(64,224,208,255), // turkuaz
    new Color(255,255,0,255), // sarı
    new Color(255,255,255,255), // beyaz
    new Color(0,0,0,255), // siyah
};

string[] colorNames = new string[13]{
    "Mavi",
    "Kahverengi",
    "Gri", // gri (192,192,192 gümüş)
    "Yeşil", // yeşil
    "Bordo", // bordo
    "Turuncu", // turuncu
    "Pembe", // pembe
    "Mor", // mor
    "Kırmızı", // kırmızı
    "Turkuaz", // turkuaz
    "Sarı", // sarı
    "Beyaz", // beyaz
    "Siyah", // siyah
};

// Use this for initialization
void Start () {
    InvokeRepeating ("changeColors", 0, 1f);
}

void changeColors(){
    int a, b;
    a = (int)Random.Range (0, colorList.Length);
    b = (int)Random.Range (0, colorList.Length);

    if (a == b) {
        do{
            a = (int)Random.Range (0, colorList.Length);
            b = (int)Random.Range (0, colorList.Length);
        }while(a == b);
        clr = colorList [a];
        txtClr = colorList [b];
        clrName = colorNames [Random.Range (0, colorNames.Length)];

    } else {
        clr = colorList [a];
        txtClr = colorList [b];
        clrName = colorNames [Random.Range (0, colorNames.Length)];
    }
}

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

}

void OnGUI() {
    GUI.skin = mySkin;
    mySkin.box.fontStyle = FontStyle.Bold;
    mySkin.box.normal.textColor = txtClr;
    //GUI.backgroundColor = Color.blue;

    Texture2D texture = new Texture2D(1, 1);
    //Set new texture as background
    mySkin.box.normal.background = texture;
    //Set the texture color
    texture.SetPixel(1,1,clr);
    // Apply all SetPixel calls
    texture.Apply();

    /*float scalex = (float)(Screen.width) / 480.0f;
    float scaley = (float)(Screen.height) / 800.0f;
    GUI.matrix = Matrix4x4.TRS(new Vector3(0, 0, 0), Quaternion.identity, new Vector3(scalex, scaley, 1));*/


    GUI.Box(new Rect(Screen.width/2 - 400,10,800,200), clrName, "box");
    //GUI.Label(new Rect(Screen.width/2, 15, 100, 20), "Hello World!");
}

}

我失踪了吗？感谢您的帮助。编辑：我检查了指数进行比较。他们不一样。

我的方法效率稍差。首先将您的颜色数组克隆到临时列表中，您可以根据需要进行更改。然后删除第一个随机颜色的索引。这是一个例子：

void changeColors()
{
    List<Color> tempColors = new List<Color>(colorList);

    // Get the first random index.
    int a = (int)Random.Range (0, tempColors.Length);  
    // Assign the colour.
    clr = tempColors[a];  
    // Remove the colour from the list so that it is impossible to select the same again.
    tempColors.RemoveAt(a); 
    // Get second index.
    int b = (int)Random.Range (0, tempColors.Length); 
    // Assign second colour.
    txtClr = tempColors[b];   
}

我希望这可以帮到你。

编辑：如果问题证明是其他问题，我认为代码清理在这里是合适的。只是为了向您展示一种不同的写作方式：

void changeColors(){
    int a,b;
    a = b = 0;

    while (a == b) 
    {
        a = (int)Random.Range (0, colorList.Length);
        b = (int)Random.Range (0, colorList.Length);
    }

    clr = colorList [a];
    txtClr = colorList [b];
    clrName = colorNames [Random.Range (0, colorNames.Length)];
}

如果我没弄错的话，这应该与你当前的代码完全相同。

如果你只需要一次只需要两种颜色，那么你为什么把它推到invokerepeating中？如果你希望它立即开始，那么invokerepeating开始时间的旁注不会为零开始时间值较小

 void Start () {
    Changecolors();
}

Answer 3

“Color使用0到1之间的浮点值，Color32使用0到255之间的字节值。
