C＃如何添加暂停功能？ [英] C# How do I add Pause function?

问题描述

这是我的密钥输入：

Here is my Key Input:

if (Input.KeyPressed(Keys.P))
            {
                gameTimer.Stop();
                string paused = "Paused\n Press Enter to continue";
                lblGameOver.Text = paused;
                lblGameOver.Visible = true;
            }

            else
            {
                if (Input.KeyPressed(Keys.Enter))
                    gameTimer.Start();
                lblGameOver.Visible = false;
            }

我在哪里错过了？游戏进入Pause，但不会恢复...

Where did I miss? The game goes to Pause, but won`t resume...

推荐答案

使用计时器进行游戏的整个想法并不是最好的。较新的方法是使用 window.requestAnimationFrame 。请参阅：

请注意在代码示例中使用回退到 window.setTimeout 。



暂停游戏非常简单。您只需为暂停/运行状态创建一些标志变量，并在游戏暂停时不处理帧。你可以看到完整的代码示例（对不起，它不是真的很小，是一个完全成熟的游戏，但发现技术类似，请参阅代码中的 states.paused ），例如，在这里：画布上的俄罗斯方块 [ ^ ]。

The whole idea of using the timer for gaming is not the best. The newer approach is using window.requestAnimationFrame. Please see:
http://paulirish.com/2011/requestanimationframe-for-smart-animating[^].

Note the use of the fallback to window.setTimeout in the code sample.

The pausing of the game is pretty much trivial. You simply create some flag variable for paused/running state and don't process frames when the game is paused. You can see the complete code sample (sorry, it's not really minimal, is a fully-fledged game, but finding the technique is similar, please see states.paused in the code), for example, here: Tetris on Canvas[^].

我自己想出来了：

I figured it out by myself:

private void Form1_KeyDown(object sender, KeyEventArgs e)
      {
          Input.ChangeState(e.KeyCode, true);

          if (Input.KeyPressed(Keys.P))
          {
              gameTimer.Stop();
          }

          if (Input.KeyPressed(Keys.Enter))
          {
              gameTimer.Start();
          }
      }

必须在Keydown下
