我使用C#在Windows Universal App上开发游戏。我的界面上有四个按钮(左,右,上,下)来移动地图上的角色。
我的问题是:如何使用键盘箭头激活我的函数Move()?
我尝试了很多来自网络的解决方案来获取按键,但大多数情况下他们只关注输入表格......

您可以使用KeyDown激活键盘。
xaml是
<Page

<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}" KeyDown="Grid_OnKeyDown">
<Button x:Name="btn" Content="K">
<Button.RenderTransform>
<CompositeTransform></CompositeTransform>
</Button.RenderTransform>
</Button>
<Grid VerticalAlignment="Bottom">
<Grid.RowDefinitions>
<RowDefinition></RowDefinition>
<RowDefinition></RowDefinition>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>

</Grid.ColumnDefinitions>
<Button Grid.Row="0" Grid.Column="0" Content="left" Click="Button_OnClick"></Button>
<Button Grid.Row="1" Grid.Column="0" Content="up" Click="Button_OnClick"></Button>
<Button Grid.Row="0" Grid.Column="1" Content="down" Click="Button_OnClick"></Button>
<Button Grid.Row="1" Grid.Column="1" Content="right" Click="Button_OnClick"></Button>
</Grid>
</Grid>

它将上下移动btn使用按钮。
你应该写代码:
private void Grid_OnKeyDown(object sender, KeyRoutedEventArgs e)
{
if (e.Key == VirtualKey.Left)
{
Move(-1, 0);
}
else if (e.Key == VirtualKey.Right)
{
Move(1, 0);
}
else if (e.Key == VirtualKey.Up)
{
Move(0, -1);
}
else if (e.Key == VirtualKey.Down)
{
Move(0, 1);
}
}
private void Move(int x, int y)
{
var temp = btn.RenderTransform as CompositeTransform;
temp.TranslateX += x;
temp.TranslateY += y;
}
private void Button_OnClick(object sender, RoutedEventArgs e)
{
var b = sender as Button;
if (b != null)
{
string str = b.Content as string;
if (str == "up")
{
Move(0, -1);
}
else if (str == "down")
{
Move(0, 1);
}
else if (str == "left")
{
Move(-1, 0);
}
else if (str == "right")
{
Move(1, 0);
}
}
}
}
你应该使用Grid.KeyDown获取密钥并使btn移动。
如果没有代码概念,请与我联系。
