尝试在 C# unity 4.69 中制作随机数生成器 [英] Trying to make a random number generator in C# unity 4.69

问题描述

根据网上的许多消息来源，这正是在 Unity 4.6 中使用 C# 制作随机数生成器的方法，我什至看到一个 youtube 视频完全按照我的方式编写，但它似乎对我不起作用，错误消息说当前上下文中不存在名称‘n’".

According to many sources online, this is exactly how to make a random number generator using C# in unity 4.6, I even saw one youtube video write it exactly how I did, but it doesn't seem to work for me, the error message says "the name 'n' does not exist in the current context".

我还查看了与此类似的 C# 问题，这些问题已在 stackoverflow 上解决并尝试了相同的解决方案，但我得到的只是错误.

I've also looked at similar C# questions to this that have been solved on stackoverflow and tried the same solutions and all I get are errors.

这是我的代码:

void Start () {
    n = Random.Range (1, 1000);
    print (n);
}

推荐答案

必须先声明一个变量，然后才能使用它.使用前声明n:

You must declare a variable before using it. Declare n before using it:

int n = 0;
void Start () 
{
    n = Random.Range (1, 1000);
    print (n);
}

或

void Start ()
{
    int n = Random.Range (1, 1000);
    print (n);
}

现在，如果出现错误:

'Random' 是 'UnityEngine.Random' 和'System.Random'

'Random' is an ambiguous reference between 'UnityEngine.Random' and 'System.Random'

那是因为System和UnityEngine都是用using System;和using UnityEngineUse

That's because System and UnityEngine are both imported with using System; and using UnityEngineUse

UnityEngine.Random.Range(1, 1000);
