我正在尝试制作类似书签的东西,我在舞台上有一个笔记,当用户点击它时,它开始拖动,用户将它放在他们想要的地方。问题是我想把这些笔记拖多次。。这是我的代码:
import flash.events.MouseEvent;
//notess is the instance name of the movie clip on the stage
notess.inputText.visible = false;
//delet is a delete button inside the movie clip,
notess.delet.visible = false;
//the class of the object i want to drag
var note:notes = new notes ;
notess.addEventListener(MouseEvent.CLICK , newNote);
function newNote(e:MouseEvent):void
{
for (var i:Number = 1; i<10; i++)
{
addChild(note);
//inpuText is a text field in notess movie clip
note.inputText.visible = false;
note.x = mouseX;
note.y = mouseY;
note.addEventListener( MouseEvent.MOUSE_DOWN , drag);
note.addEventListener( MouseEvent.MOUSE_UP , drop);
note.delet.addEventListener( MouseEvent.CLICK , delet);
}
}
function drag(e:MouseEvent):void
{
note.startDrag();
}
function drop(e:MouseEvent):void
{
e.currentTarget.stopDrag();
note.inputText.visible = true;
note.delet.visible = true;
}
function delet(e:MouseEvent):void
{
removeChild(note);
}
任何帮助都将不胜感激。
您需要在拖放时创建note类的新实例,从拖动的note中复制位置和其他变量,将新note添加到stage中,并将拖动的notes返回到其原始位置。
类似于:
function drop($e:MouseEvent):void
{
$e.currentTarget.stopDrag();
dropNote($e.currentTarget as Note);
}
var newNote:Note;
function dropNote($note:Note):void
{
newNote = new Note();
// Copy vars:
newNote.x = $note.x;
newNote.y = $note.y;
// etc.
// restore original note.
// You will need to store its original position before you begin dragging:
$note.x = $note.originalX;
$note.y = $note.orgiinalY;
// etc.
// Finally, add your new note to the stage:
addChild(newNote);
}
这真的是伪代码,因为我不知道你是否需要将新注释添加到列表中,或者将其链接到原始注释。如果你谷歌ActionScript拖放复制,你会发现更多的例子。
我认为您不是针对拖动函数中的拖动对象和对象实例化中的问题
for (var i:Number = 1; i<numberOfNodes; i++) {
note = new note();
addChild(note);
...
....
}
function drag(e:MouseEvent):void{
(e.target).startDrag();
}
如果您正在拖动多种类型的对象(例如Notes和Images),您可以执行类似的操作,而不是对要实例化的对象类型进行硬编码。
function drop(e:MouseEvent):void{
// Get a reference to the class of the dragged object
var className:String = flash.utils.getQualifiedClassName(e.currentTarget);
var TheClass:Class = flash.utils.getDefinitionByName(className) as Class;
var scope:DisplayObjectContainer = this; // The Drop Target
// Convert the position of the dragged clip to local coordinates
var position:Point = scope.globalToLocal( DisplayObject(e.currentTarget).localToGlobal() );
// Create a new instance of the dragged object
var instance:DisplayObject = new TheClass();
instance.x = position.x;
instance.y = position.y;
scope.addChild(instance);
}
