您当前的位置: 怎么用flash做这种效果:
1.在二维坐标轴(x,y)里一条能慢慢画出来的线;
2.这条线的各各点是从数据库中读出的数据所确定的;
3.可以实现实时更新;(也可以过一段时间更新一次)
------解决方案--------------------
通过Line对象绘制线条参考:
- Assembly code
package drawhelper
{
import flash.geom.Point;
public class line extends stage
{
public var uAlpha:Number = 1;
public var uColor:uint = 0xffffff;
public var uWidth:Number = 1.8;
//初始化参数默认值
public function line(uA:Number=1,uC:uint=0xffffff,uW:Number = 1.0)
{
this.uAlpha = uA;
this.uColor = uC;
this.uWidth = uW;
}
//初始化绘制线条
public function drawLine(pointB:Point,pointE:Point):void
{
graphics.clear();
graphics.lineStyle(uWidth,uColor,uAlpha);
graphics.moveTo(pointB.x,pointB.y);
graphics.lineTo(pointE.x,pointE.y);
}
//追加线条
public function drawLines(lineToX:Number,lineToY:Number):void
{
graphics.lineStyle(uWidth,uColor,uAlpha);
graphics.lineTo(lineToX,lineToY);
}
//清除线条
public function clearLine():void
{
graphics.clear();
}
}
}
