控制台闪烁 [英] Console Flicker

问题描述

我正在控制台模式下创建一个基于文本的小型游戏.我想通过添加一些动画(例如动画文本和框来为其打开和关闭进行动画处理)来给它加点趣味.为此，我创建了一个缓冲区(如果是CHAR_INFO，则为数组)并将所有内容写入该数组，并且每次更新一次(屏幕每秒更新30次)，我使用WriteConsoleOutput来显示缓冲区.这样效果很好，动画看起来真的很棒.但是，屏幕闪烁存在问题.当我每秒多次调用WriteConsoleOutput时，似乎会发生这种情况，并且您可以看到屏幕上不断更新的行.有什么方法可以消除这种闪烁?我已经在互联网上搜寻了3天，没有运气就读过有关此问题的电子邮件.我已经看到了许多文本模式应用程序，例如Turbo Vision甚至是Edit，它们可以毫无问题地非常快速地显示很多字符，所以我知道这是可能的，但不知道如何去做.我试过创建2个屏幕缓冲区，然后切换写入一个，然后显示另一个，反之亦然(在2个之间切换，这样我就可以写到一个离屏的缓冲区，并在完成时显示它)，但是即使在两个还有2个屏幕缓冲区.我该如何停止呢?

注意:当应用程序以全屏模式运行时，不会发生闪烁.

感谢您提出任何建议.

I'm creating a small text based game in console mode.  I want to spice it up a little by having a few animations like animated text and boxes that animate their opening and closing.  To do this I have created a buffer (an array if CHAR_INFOs) and write everything to that array and once per update (the screen updates at 30 times per second) I use WriteConsoleOutput to display the buffer.  This works great and the animations look real nice.  However there is a problem with the screen flickering.  This seems to happen when I call WriteConsoleOutput too many times a second and you can see lines going through the screen as it updates.  Is there any way to eliminate this flicker?  I've been searching the internet for 3 days reading and emailing about this with no luck.  I have seen many text mode applications that like Turbo Vision and even Edit that can display lots of characters very quicly with no problem so I know it's possible, but have no idea how to do it.  I've tried creating 2 screen buffers and switching writing to one and display the other and vice versa (switching between the 2 so I could write to an off screen one and display it when it is finished) but the flickering occurs even when switching between 2 screen buffers as well.  How can I stop this?

Note: The flicker does not occur when the app is run in full screen mode.

Thanks for any advice.

推荐答案

我不在Visual Basic中编程，但是我在BASIC中编程，而我目前正在开发的基于Sprite的2d游戏也遇到了同样的麻烦. BASIC程序和Visual Basic控制台应用程序几乎是同一回事.

I don't program in Visual Basic, but I do in BASIC, and I'm having the same trouble with a sprite based 2d game I'm developing at the moment. BASIC programs and Visual Basic console apps are the same thing just about.
