清除键盘缓冲区或阻止输入(C#控制台)

Question

"提前为糟糕的编码道歉"XD

问题是，当我切换到新贴图时，过渡动画开始(变暗并显示新贴图((在代码中，这是NextMap(((在这部动画中，我将有时间再做几次移动(比如向左移动(，当动画结束时，我的角色会立即移动相同数量的移动，我需要他站在地图之间的过渡附近。我想在动画结束时以某种方式清除键盘缓冲区。有可能以某种方式解决这个问题吗？

(为了更好地理解我的问题，请运行此代码并检查我的操作(

在NextRoomX()方法的底部，调用ClearBuffer():

static void ClearBuffer()
{
while (Console.KeyAvailable) {
Console.ReadKey(false);
}            
}
