如何让计算机选择随机变量并显示它？ [英] How do I get the computer to choose a random variable and display it?

问题描述

我在AppLab中编码，这是Code.Org中使用的编码语言。



我正试图让计算机显示在一个文本框中，四个文本变量之一，标题为正手，反手，切片或粉碎。我遇到的问题是，唯一可用的Randomizer功能是RandomNumber（＃，＃）的功能，你可以猜测，它只接受数字。因此，我尝试为每个文本变量分配一个数字，并让计算机随机选择1-4之间的数字，其中每个数字都分配了一个文本变量，如正手，反手等。



我不知道怎么做。有什么帮助吗？

解决方案

你有你的兰特[1,2,3,4]

你有阵列[word，word，word，word]



triforce你有你的解决方案



array [rand] =word



在AppLab中也是如此，因为它有多种语言版本。 triforce我的猜测是执行不是你的问题，而是理解。

I'm coding in AppLab, the coding language used in Code.Org.

I'm trying to get the computer to display, in a text box, one of four text variables, titled "Forehand, Backhand, Slice, or Smash." The problem I'm having is that the only Randomizer function available is that of the RandomNumber(#,#), which as you can probably guess, only accepts numbers. Therefore, I attempted to assign each text variable with a number, and to have the computer randomly select a number between 1-4, where each number is assigned a text variable like Forehand, Backhand, etc.

I've no idea how to do it though. Any help?

解决方案

You have your rand [1,2,3,4]
you have your array ["word","word","word","word"]

"triforce" you have your solution

array[rand] = "word"

That is true in AppLab as it is in many languages. "triforce" my guess is that the execution is not your issue, but understanding.
