击键

对于那些经典游戏 ...你可以使用键盘！

// mouseBox has some keyboard methods that have not been// documented very well.  Test them to see if they will// do what you need; there are issues with the mouse box// losing key focus and issues with special keys (like "s")// that enter selection-cursor mode and lose the key focus.// it looks like the numeric keypad and the arrow keys work // pretty well.New Window( "test", mb = MouseBox( tb = Text Box( "try the arrow keys" ) ) );mb << setkey( Function( {this, key}, tb << settext( key ) ) );mb << setkeyenable( 1 );mb << setfocus;

这可以回到JMP 11。  这里的反馈会很棒。

回复：击键

谢谢Craige分享...... 这肯定会提高我的高分。

我发布了一个新版本蛇使用此setkey函数设置我的“下一个方向”变量，它似乎运行良好

//启用键盘控件

mb << setkey（

  功能（{this，key}，

    如果（key ==“DOWN”，:: nextdir = 1）;

    如果（key ==“LEFT”，:: nextdir = 2）;

    如果（key ==“UP”，:: nextdir = 3）;

    如果（key ==“RIGHT”，:: nextdir = 4）;

  ）

）;
