英文:
I'm developing a game where the there are 3 strings and one of them will be displayed in the Text UI on the screen, but before displaying it, I want all the three strings to repeat quickly after each other in one text UI (To make it obvious that the text is randomized). So I believe a loop is required here, but it didn't work.
Here is what I tried.
string[] arr = new string[3];
void Start()
{
arr[0] = "option1";
arr[1] = "option2";
arr[2] = "option3";
}
foreach (string s in arr)
{
buttonText.SetText(s);
}
please help, how can I display all strings repeatedly after each other fast in the single UI Text?

你的基本方法方向是正确的，但缺少了协程。
协程允许你在多个帧之间分配任务。在Unity中，协程是一种方法，它可以暂停执行并将控制权返回给Unity，然后在下一帧继续执行。
你只需要进行以下轻微更改：
private IEnumerator Foo()
{
var wait = new WaitForSeconds(0.1f);
foreach (string s in arr)
{
buttonText.SetText(s);
yield return wait;
}
}
根据时间有不同类型的等待，包括基于时间（Unity的Time，受时间刻度影响）、帧以及读取时间（不受时间刻度影响）。而且你还可以使用另一个协程作为yield return来链接这些协程。
参考：Unity手册：协程
英文:
Your base approach is in the right direction but is missing the Coroutine.
A coroutine allows you to spread tasks across several frames. In Unity, a coroutine is a method that can pause execution and return control to Unity but then continue where it left off on the following frame.
You just had to make minor changes as follows:
private IEnumerator Foo()
{
var wait = new WaitForSeconds(0.1f);
foreach (string s in arr)
{
buttonText.SetText(s);
yield return wait;
}
}
There are different types of wait based on Time(Unity's Time. This is affected by timescale), frame, and read-time(This is not affected by timescale). And you can also use another coroutine as yield return to chain the coroutines.
