[英]Assign a random array string to a text component - Unity 4.6, uGUI
I'm creating an array with a list of descriptions (strings) that I need to choose randomly and then assign to a text component in a gamobject. 我正在创建一个包含描述(字符串)列表的数组,需要随机选择这些描述(字符串),然后分配给gamobject中的文本组件。 How do I do that?
我怎么做? I've created the array but I don't know where to go from there.
我已经创建了数组,但是我不知道从那里去哪里。 Can anyone help me with this?
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);
}
}
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;
}
}
string myString = animalDescriptions[new Random().Next(animalDescriptions.Length)];
You might want to store that new Random()
somewhere else so that you don't seed a new one every time you want a new random description, but that's about it. 您可能希望将该
new Random()
存储在其他位置,这样就不必每次都想要一个新的随机描述时就播下一个new Random()
,仅此而已。 You can do that by initializing your Random
elsewhere, and simply using your instance of it in Start
: 您可以通过在其他地方初始化
Random
并在Start
简单使用它的实例来做到这一点:
Random rand = new Random();
// ... other code in your class
void Start()
{
string myString = animalDescriptions[rand.Next(animalDescriptions.Length)];
// ... the rest of Start()
}
