Question

我试图制造一些可移动的事例,这些事例是可分割的,而且有一条线连接它们,自动更新。

The thing is: The original line just goes randomly and doesn t update as the instances (mc1, mc2) are being dragged. Here is the code I have got so far:

 mc1.addEventListener(MouseEvent.MOUSE_DOWN, function (e:MouseEvent):void
{
    e.currentTarget.startDrag();
});

mc1.addEventListener(MouseEvent.MOUSE_UP, function (e:MouseEvent):void
{
    e.currentTarget.stopDrag();
});
mc2.addEventListener(MouseEvent.MOUSE_DOWN, function (e:MouseEvent):void
{
    e.currentTarget.startDrag();
});

mc2.addEventListener(MouseEvent.MOUSE_UP, function (e:MouseEvent):void
{
    e.currentTarget.stopDrag();
});

var mc:MovieClip = new MovieClip();
mc.graphics.beginFill(0x000000);
mc.graphics.lineStyle(2,0x000000);

//start drawing the line
mc.graphics.moveTo(mc1.x,mc1.y);
mc.graphics.lineTo(mc2.x,mc2.y);
mc.graphics.endFill();

//Position your new movie clip
addChild(mc);

谁能告诉我我,我会错了吗?

Thanks a lot of any help !!!!

Answer 1

你们需要做的是抓住用户的移动,因为(s)正在拖拉电影剪辑。

First create a isDragging variable var isDragging:Boolean = false; and set this to true when mouse down and false when mouse up.

之后加上“MouseEvent”。备忘录SE_MOVE活动听取人对时间表的注意

addEventListener(MouseEvent.MOUSE_MOVE, function (e:MouseEvent):void
{
    if (isDragging) {
        drawConnectiveLine(mc1, mc2);
    }
    return;
});

方法<代码>drawConnectiveLine将更新线性矢量结构,以移至电影剪辑的{x, y}。

function drawConnectiveLine(d:DisplayObject, d2:DisplayObject):void {
    mc.graphics.clear();
    mc.graphics.lineStyle(2,0);
    mc.graphics.moveTo(d.x,d.y);
    mc.graphics.lineTo(d2.x,d2.y);
}

www.un.org/Depts/DGACM/index_spanish.htm 更正:

var isDragging:Boolean = false;
var mc:MovieClip = new MovieClip();
mc.graphics.lineStyle(2,0);
mc.graphics.moveTo(mc1.x,mc1.y);
mc.graphics.lineTo(mc2.x,mc2.y);
addChild(mc);

mc1.addEventListener(MouseEvent.MOUSE_DOWN, function (e:MouseEvent):void
{
    isDragging = true;
    e.currentTarget.startDrag();
});

mc1.addEventListener(MouseEvent.MOUSE_UP, function (e:MouseEvent):void
{
    isDragging = false;
    e.currentTarget.stopDrag();
});

mc2.addEventListener(MouseEvent.MOUSE_DOWN, function (e:MouseEvent):void
{
    isDragging = true;
    e.currentTarget.startDrag();
});
mc2.addEventListener(MouseEvent.MOUSE_UP, function (e:MouseEvent):void
{
    isDragging = false;
    e.currentTarget.stopDrag();
});
addEventListener(MouseEvent.MOUSE_MOVE, function (e:MouseEvent):void
{
    if (isDragging) {
        mc.graphics.clear();
        mc.graphics.lineStyle(2,0);
        mc.graphics.moveTo(mc1.x,mc1.y);
        mc.graphics.lineTo(mc2.x,mc2.y);
    }
});

Answer 2

以下各点可能有助于你。

mc.graphics.clear();
//mc.graphics.beginFill(0x000000); //no need fills
mc.graphics.lineStyle(2,0);

//start drawing the line
mc.graphics.moveTo(mc1.x,mc1.y);
mc.graphics.lineTo(mc2.x,mc2.y);
//mc.graphics.endFill(); //no need to end it.
