Question

所以我一直在环顾四周，我尝试了一些不同的东西，似乎仍然无法使用随机颜色生成器来处理这个用户绘制的线条。这是我正在处理用户绘制线的代码。

var myshape:Shape;
myshape = new Shape();
myshape.graphics.lineStyle(8, 0x99CC33);
myshape.filters = [new BlurFilter()];

function activateDraw(event:MouseEvent):void{
    myshape.graphics.moveTo(mouseX, mouseY);
    addChild(myshape);

    stage.addEventListener(MouseEvent.MOUSE_MOVE, lineDraw);
    stage.addEventListener(MouseEvent.MOUSE_UP, stopDraw);
}

function lineDraw(event:MouseEvent):void{
    myshape.graphics.lineTo(mouseX, mouseY);
    event.updateAfterEvent();
}

function stopDraw(event:MouseEvent):void{
    stage.removeEventListener(MouseEvent.MOUSE_MOVE, lineDraw);
    stage.removeEventListener(MouseEvent.MOUSE_UP, stopDraw);

    myshape.graphics.clear();
    myshape.graphics.lineStyle(12, 0x99CC33);
}

想出来了！

var myshape:Shape;
myshape = new Shape();
myshape.graphics.lineStyle(8, Math.random() * 0xFFFFFF);
myshape.filters = [new BlurFilter()];

function activateDraw(event:MouseEvent):void{
    myshape.graphics.moveTo(mouseX, mouseY);
    addChild(myshape);

    stage.addEventListener(MouseEvent.MOUSE_MOVE, lineDraw);
    stage.addEventListener(MouseEvent.MOUSE_UP, stopDraw);
}

function lineDraw(event:MouseEvent):void{
    myshape.graphics.lineTo(mouseX, mouseY);
    event.updateAfterEvent();
}

function stopDraw(event:MouseEvent):void{
    stage.removeEventListener(MouseEvent.MOUSE_MOVE, lineDraw);
    stage.removeEventListener(MouseEvent.MOUSE_UP, stopDraw);

    myshape.graphics.clear();
    myshape.graphics.lineStyle(8, Math.random() * 0xFFFFFF);
}
