如何在轴（x和y）中拖动对象，但不在as3中对角拖动-Howtodragobjectsinaxis(bothxandy)butnotdiagonallyinas3

It's impossible to do it. When your mouse is going to move diagonally, what will you do? An alternative could be something like that, where your object moves along the speediest axis:

这是不可能的。当你的鼠标要对角移动时,你会怎么做?替代方案可能是这样的,您的对象沿着最快的轴移动:

var oldx:int;
var oldy:int;
var sx:int;
var sy:int;

function run(e:Event):void
{
    sx = Math.abs(mouseX - oldx);
    sy = Math.abs(mouseY - oldy);

    if (sx > sy) {
        c.x = mouseX;
    } else {
        c.y = mouseY;
    }

    oldx = mouseX;
    oldy = mouseY;
}

stage.addEventListener(Event.ENTER_FRAME, run);

Other solution

Another alternative consists in calculating the angle of your mouse:

另一种方法是计算鼠标的角度:

var oldx:int;
var oldy:int;
var rd:Number;
var l1:Number = Math.PI / 4;
var l2:Number = 3 * Math.PI / 4;

function run2(e:Event):void
{
    rd = Math.atan2(mouseX - oldx, mouseY - oldy);

    if ((rd > l1 && rd  -l2)) {
        c.x = mouseX;
    } else {
        c.y = mouseY;
    }

    oldx = mouseX;
    oldy = mouseY;

}
stage.addEventListener(Event.ENTER_FRAME, run2);

import flash.geom.Rectangle;
import flash.events.MouseEvent;
var tempx:Number=0;
var tempy:Number=0;
var count:int=0;
stage.addEventListener(MouseEvent.MOUSE_UP,remov)
bl.addEventListener(MouseEvent.MOUSE_DOWN,func)
function func  (f:MouseEvent)
{
    tempx=Math.abs(stage.mouseX);
    tempy=Math.abs(stage.mouseY);
    stage.addEventListener(MouseEvent.MOUSE_MOVE,mov)
}
function mov(h:MouseEvent)
{
    count+=1;
    if (count==4)
    {
    count=0;
    var Xval:Number=tempx-stage.mouseX;
    var Yval:Number=tempy-stage.mouseY;
    if(Math.abs(Xval)>Math.abs(Yval))
    {
    bl.startDrag(false,new Rectangle(0,bl.y,stage.stageWidth,0))
    trace ("X dragg")
    trace(Xval+""+""+Yval)
    }
    else
    {

        trace ("YY drag")
        trace(Xval+""+""+Yval)
        bl.startDrag(false,new Rectangle(bl.x,0,0,stage.stageHeight))
    }
    stage.removeEventListener(MouseEvent.MOUSE_MOVE,mov)
    }
}
function remov(y:MouseEvent)
{
    bl.stopDrag();
}

bl is the mc name this works fine for me....Moving either in x or y axis alone....

bl是mc名称这对我来说很好....单独在x或y轴移动....
