Twaver-HTML5基础学习(15)跟随者(Follower)

跟随者(Follower)

跟随者跟随宿主移动而移动，具有依附的功能，通常用于设备面板，如端口依附在板卡上。

Follower常用的方法如下：

//设置宿主
get/setHost: function(host)
//是否依附在某个节点上
isHostOn: function(node)
//是否是相互依附关系
isLoopedHostOn: function(node)

创建跟随者元素：

 var Follower1 = new twaver.Follower({
    
     name: 'Follower1', location: {
    
     x: 300, y: 300 } });

跟随者–》跟随其他节点设置

 var node1 = new twaver.Node({
    
     name: 'node1', location: {
    
     x: 100, y: 100 } });
 box.add(node1)
 var node2 = new twaver.Node({
    
     name: 'node2', location: {
    
     x: 300, y: 600 } });
 box.add(node2)
 var Follower1 = new twaver.Follower({
    
     name: 'Follower1', location: {
    
     x: 300, y: 300 } });
 var Follower2 = new twaver.Follower({
    
     name: 'Follower2', location: {
    
     x: 400, y: 400 } });
 box.add(Follower1);
 box.add(Follower2);
 Follower1.setHost(node1);
 Follower2.setHost(node2);

跟随者1跟随node1;
跟随者2跟随node2;
