下面的代码将检测鼠标方位，并将结果展示在舞台文本域上。
复制代码function
checkDirection(e:MouseEvent):void
{
getHorizontalDirection();
getVerticalDirection();
dir.text = ”x: ” + xDir + ”, y: ” + yDir;
}
检测鼠标的方向.
复制代码//水平方向
function getHorizontalDirection():void
{
previousX = currentX; //检测刚刚的地址
currentX = stage.mouseX; //获取当前的地址
if (previousX > currentX) //将两个地址进行比较来确定方向
{
xDir = “left”;
}
else if (previousX < currentX)
{
xDir = “right”;
}
else
{</p>
xDir = “none”;
}
}
//垂直方向
<p></p>
function getVerticalDirection():void
{
previousY = currentY; //检测刚刚的地址
currentY = stage.mouseY; //获取当前的地址
if (previousY > currentY) //将两个地址进行比较来确定方向
{
yDir = “up”;
}
else if (previousY < currentY)
{
yDir = “down”;
}
else
{
<p></p>
<p>yDir = “none”;
}
}
第七步：运行函数
添加下面的代码来运行函数。当 getMouseDirection() 开始函数运行，就会建立一个可以启动方向指示器的鼠标运动事件监听器
复制代码getMouseDirection();
复制代码package
{
import flash.display.MovieClip;
import flash.text.TextField;</p>
<p>public class MouseMoveDemo extends MovieClip
{
public var previousX:Number = 0;
public var previousY:Number = 0;
public var currentX:Number = 0;
public var currentY:Number = 0;
public var xDir:String;
public var yDir:String;
public var dir:TextField = new TextField();
public function MouseMoveDemo()
{
getMouseDirection();
}</p>
<p>public function getMouseDirection():void</p>
<p>{
dir.width = stage.stageWidth;
addChild(dir);
stage.addEventListener(MouseEvent.MOUSE_MOVE, checkDirection);
}
public function
checkDirection(e:MouseEvent):void
{
getHorizontalDirection();
getVerticalDirection();
dir1.text = “x: ” + xDir
dir2.text = “y: ” + yDir;
}
public function getHorizontalDirection():void
{
previousX = currentX;
currentX = stage.mouseX;<
if (previousX > currentX)
{
xDir = “left”;
}
else if (previousX < currentX)
{
xDir = “right”;
}
else
{
xDir = “none”;
}
}
public function getVerticalDirection():void
{
previousY = currentY;
currentY = stage.mouseY;
