这是我的代码：

var drawingLine:Sprite = new Sprite();
addChild(drawingLine);

 stage.addEventListener(MouseEvent.MOUSE_DOWN, mouseDownHandler);
stage.addEventListener(MouseEvent.MOUSE_UP, mouseUpHandler);


function mouseDownHandler(event:MouseEvent):void {
    timer.start();
    drawingLine.graphics.lineStyle(3, coloursArray[position]);
    drawingLine.graphics.moveTo(mouseX, mouseY);
    stage.addEventListener(MouseEvent.MOUSE_MOVE, mouseMoveHandler);
}


function mouseMoveHandler(event:MouseEvent):void {
    drawingLine.graphics.lineTo(mouseX, mouseY);
}

 function mouseUpHandler(event:MouseEvent):void {
    timer.stop();
    stage.removeEventListener(MouseEvent.MOUSE_MOVE, mouseMoveHandler);
}


function changeColour(e:TimerEvent):void{
    position++;

您可以使用copyForm method的{{1}}：

将源Graphics对象中的所有绘图命令复制到调用Graphics对象。

一般表格：

destinationObject.graphics.copyFrom（sourceObject.graphics）;

您的代码：

Graphics class

在舞台上画线并行
