Java实现按键精灵的示例代码

实现效果

背景

对于日常刷课每十分钟点击“继续学习”的行为，或者说是单机游戏里某项重复的行为想使其实现“自动化”。我们可以通过javafx里的robot类来实现。

难点

• 窗口穿透
• 鼠标行为的记录

搭建程序

需要掌握的知识

窗口测试

@override
public void start(stage stage) throws exception {
    scene scene = new scene(new pane (), 320, 240);
    stage.settitle("按键精灵!");
    stage.setscene(scene);
    stage.show();
}

获取鼠标位置

robot robot = new robot ();
//获得鼠标位置
point2d mp = robot.getmouseposition ();
system.out.println (mp);

模拟鼠标单击

左

mousebutton.primary

右

mousebutton.secondary

滚轮子

mousebutton.middle

模拟鼠标移动

//鼠标移动
robot.mousemove (new point2d (800,800));

鼠标行为监听

//监听鼠标单击
pane.setonmouseclicked (e->{          
     system.out.println (e.getbutton ());
     system.out.println (e.getscenex ());
     system.out.println (e.getsceney ());
});
//监听鼠标键入
pane.setonmousepressed (e->{});
//监听鼠标释放
pane.setonmousereleased (e->{});
//监听鼠标在摁着某个键时的拖动
pane.setonmousedragged (e->{});

完整源码及详细解释

public class qmapp extends application {
    @override
    public void start(stage stage) throws exception {
        /**
         * 内部类，将每次鼠标的行为以及坐标记录下来
         */
        class mymouseevent{
            //鼠标行为
            mousebutton mb;
            //类型
            eventtype et;
            //坐标
            point2d point2d;
            public mymouseevent(mousebutton mb, eventtype et, point2d point2d) {
                this.mb = mb;
                this.et=et;
                this.point2d = point2d;
            }
        }
        //创建面板
        vbox pane = new vbox ();
        //对齐方式
        pane.setalignment (pos.top_left);
        //robot关键对象
        robot robot = new robot ();
        //记录鼠标行为
        linkedlist<mymouseevent> list = new linkedlist<> ();
        //开始
        button beginb = new button ("开始");
        beginb.settextfill (color.red);
        //结束
        button endb = new button ("结束");
        endb.settextfill (color.red);
        pane.getchildren ().addall (beginb,endb);
        //点击“开始”按钮时，鼠标行为储存进列表
        beginb.setonmouseclicked (m->{
            pane.setonmousedragged (e->{
                list.add (new mymouseevent (e.getbutton (),e.geteventtype (),new point2d (e.getscenex (),e.getsceney ())));
            });
            pane.setonmousepressed (e->{
                list.add (new mymouseevent (e.getbutton (),e.geteventtype (),new point2d (e.getscenex (),e.getsceney ())));
            });
            pane.setonmousereleased (e->{
                list.add (new mymouseevent (e.getbutton (),e.geteventtype (),new point2d (e.getscenex (),e.getsceney ())));
            });
        });
        //点击“结束”按钮时，鼠标行为储存进列表
        endb.setonmouseclicked (e->{
            pane.getchildren ().remove (beginb);
            for (int i = 0; i < list.size (); i++) {

                //每次鼠标模拟都将窗口透明，实现穿透
                stage.setopacity (0);
                if (list.get (i).et== mouse_dragged){
                    robot.mousepress (list.get (i).mb);
                }else {
                    robot.mousemove (list.get (i).point2d);
                    robot.mouseclick (list.get (i).mb);
                }
                try {
                    //为了效果明显，进行延迟
                    thread.sleep (50);
                } catch (interruptedexception ex) {
                    ex.printstacktrace ();
                }
            }
        });
        //面板不参与计算边界。鼠标点击事件发生后，会计算应该是哪个组件位于鼠标所在点的位置，而该面板因为不参与边界计算，所以也不会捕获到鼠标事件
        pane.setpickonbounds(false);
        //窗口在前，不能拖到，都没有
        stage.initstyle (stagestyle.undecorated);
        //窗口最大化
        stage.setmaximized (true);
        //窗口透明度，为了使得开始按钮不会消失同时可以看见其他窗口，半透明
        stage.setopacity (0.3);
        scene scene = new scene(pane);
        stage.settitle("按键精灵");
        stage.setscene(scene);
        stage.show();
    }


    public static void main(string[] args) {
        launch (args);
    }
}
