XNA-键盘输入 [英] XNA - Keyboard Input

问题描述

我今天才刚开始使用XNA Framework 4.0，我想知道最简单的方法是从键盘获取输入.我在C#中认识到很多C ++，但是它的整个Java方面对我来说都是陌生的.再加上XNA，这有点令人困惑，因此请具体说明并举一些例子.谢谢.

I just started using XNA Framework 4.0 today, and I was wondering what the easiest way was to get input from the keyboard. I recognize a lot of C++ in C# but the whole Java side of it is alien to me. This coupled with XNA is a little confusing so, please be specific and give examples. Thanks.

推荐答案

如果您对VS中的对象浏览器感到不满意，建议您查看Microsoft.Xna.Framework.Input.Keyboard/Keyboardstate.这些条目将向您显示现成功能方面的可用功能.另外，您可以查看MSDN或遵循Creator's Club上的教程.我将发布一个简短的代码片段，以检查特定的击键.

If you're comfortable mucking around with the Object Browser in VS, I'd advise looking at Microsoft.Xna.Framework.Input.Keyboard/Keyboardstate. These entries will show you what you have available to you in terms of ready-made functions. Alternatively, you could look on MSDN or follow a tutorial on Creator's Club. I'll post a quick snippet that checks for a specific keystroke.

currentState = Keyboard.GetState();

if(currentState.IsKeyDown(theKey) && previousState.IsKeyUp(theKey))
{
   //Do something here
}

previousState = currentState;

theKey是在此代码段范围之外定义的参数.您可以将Key设置为一个特定的值，您希望在按下该键时触发特定的程序行为(在上面片段中的注释位置). theKey定义为:

theKey is a parameter that is defined outside of the scope of this snippet. You could set theKey to a specific value that you would want to trigger some specific program behavior on pressing (at the commented location in the fragment above). theKey is defined as:

Keys theKey

previousState和currentState定义为:

previousState and currentState are defined as:

private static KeyboardState currentState;
private static KeyboardState previousState;

虽然可能不是最漂亮的方法，但它确实有效，并且是一个非常简单的示例.希望有帮助.

While perhaps not the prettiest way of doing that, it works and is a fairly straightforward example to build from. Hope that helps.
