Question

我正在创建一个数组，其中包含我需要随机选择的描述（字符串）列表，然后分配给gamobject中的文本组件。我怎么做？我已经创建了阵列，但我不知道从那里去哪里。谁能帮我这个？

public string[] animalDescriptions = 
{
    "Description 1",
    "Description 2",
    "Description 3",
    "Description 4",
    "Description 5",
};


void Start () 
{

    string myString = animalDescriptions[0];
    Debug.Log ("You just accessed the array and retrieved " + myString);

    foreach(string animalDescription in animalDescriptions)
    {
        Debug.Log(animalDescription);
    }
}

Answer 1

using UnityEngine;
using System.Collections;
using UnityEngine.UI;

public class Test : MonoBehaviour 
{
public Text myText;

public string[] animalDescriptions = 
{
    "Description 1",
    "Description 2",
    "Description 3",
    "Description 4",
    "Description 5",
};

void Start()
{
    string myString = animalDescriptions [Random.Range (0, animalDescriptions.Length)];
    myText.text = myString;
}
}

Answer 2

string myString = animalDescriptions[new Random().Next(animalDescriptions.Length)];

您可能希望将new Random()存储在其他位置，以便每次想要新的随机描述时都不会播种新的，但这就是它。您可以通过在其他位置初始化Random并在Start中简单地使用您的实例来实现这一点：

Random rand = new Random();
// ... other code in your class
void Start()
{
    string myString = animalDescriptions[rand.Next(animalDescriptions.Length)];
    // ... the rest of Start()
}
