在XNA中如果我们需要输入文字,那么我们就需要使用到软键盘了,在XNA中使用软键盘要用到Guide.BeginShowKeyboardInput方法,由于游戏的Update是会不断地执行的,所以要由Guide.IsVisible来检查弹出输入框是否已经显示出来了。
Guide.BeginShowKeyboardInput方法的参数
PlayerIndex 玩家的编号,手机是PlayerIndex.One
Title 输入窗口的标题
Description 输入窗口的描述
DefaultText 默认的文字
Callback 回调的方法
State 使用者想要传送的物件
Guide.BeginShowMessageBox时弹出一个窗口没有软键盘输入,这个方法的参数分別是
Title 窗口的标题
Text 窗口的文字
Buttons 按钮
FoucsButton 预设的按钮
Icon 图标
Callback 回调的方法
State 使用者想要传送的物件
