vb.net倒计时 [英] vb.net countdown

问题描述

在我的一个项目中，一个游戏，我需要显示一个倒计时:3 ... 2 ... 1 ...开始！

In one of my projects, a game, i need to display a countdown: 3... 2... 1... Start!

我在表单上放置了一个标签，没有文本.现在，我想更改文本，等待一秒钟，然后再次更改，依此类推.

I've placed a label on my form, with no text. Now i want to change the text, wait for one second, then change it again, and so on.

我不想使用timer.tick事件，因为我已经有几个计时器，即使我正确命名它也会变得非常混乱.

I don't want to use timer.tick event, because i already have several timers, and it'll get very confusing, even if i name it properly.

我需要使用threading.thead.sleep.

I need to use threading.thead.sleep.

我当前遇到的问题是等待3秒钟，将文本更改为开始！"，然后再过一秒钟，它将继续执行我的程序.为什么它不显示其他3条消息?

the problem with what i currently have is it waits 3 seconds, changes the text to 'Start!', and then after another second, it continues my program. Why does it not display the other 3 messages?

我尝试使用文本框并更改文本.同样的结果.我试过几个标签，一个在另一个标签上，并使用label1.hide()和label1.show().结果相同.

I have tried using a textbox, and changing the text. same result. i've tried several labels, one on top of the other, and using label1.hide() and label1.show(). same result.

我该怎么做?

Label1.Text = "3..."
Threading.Thread.Sleep(1000)
Label1.Text = "2..."
Threading.Thread.Sleep(1000)
Label1.Text = "1..."
Threading.Thread.Sleep(1000)
Label1.Text = "Start!"

Threading.Thread.Sleep(1000)

推荐答案

尝试添加Label1.在设置了Labels文本的每一行之后刷新，然后再次使线程休眠.

Try adding Label1.Refresh after each line where the Labels text is set prior to sleeping the thread again.
