AS3 - 从一个阵列被选中preventing重复 [英] AS3 - Preventing duplicates from being selected from an array

问题描述

我有八串，我想（使用文本域）在舞台上放置一个随机顺序的数组。

I've got an array of eight strings that I want to place on the stage (using TextFields) in a random order.

我可以选择任意包含字符串的8没有问题，用的Math.random挑选了一批0-7之间，并把该项目的索引搬上了舞台。

I can select any 8 of the strings without a problem, using Math.random to pick a number between 0-7 and placing the item at that index onto the stage.

但我被添加奋力prevent重复。有没有人有什么建议？

But I'm struggling to prevent duplicates from being added. Does anyone have any suggestions?

感谢您

推荐答案

洗牌数组，然后通过它循环。一些很好的例子可以在这里找到：

Shuffle the array, then loop through it. Some great examples can be found here:
