这是我的代码:
private function drawRect():Sprite{
var rect:Sprite = new Sprite();
rect.name = "rectName";
rect.graphics.beginFill(0xffff00);
rect.graphics.lineStyle(1,0x000000);
rect.graphics.drawRect(0,0,6,6);
rect.graphics.endFill();
rect.addEventListener(MouseEvent.MOUSE_OVER, changeColor);
rect.addEventListener(MouseEvent.MOUSE_OUT, changeColorBack);
return rect;
}
private function changeColor(e:MouseEvent):void{
var newColor:ColorTransform = new ColorTransform();
newColor.color = 0x00ffff;
e.target.transform.colorTransform = newColor;
}
private function changeColorBack(e:MouseEvent):void{
var newColor:ColorTransform = new ColorTransform();
newColor.color = 0xffff00;
e.target.transform.colorTransform = newColor;
}
changeColor和changeColorBack函数可以工作,但不是我希望它们如何工作。它们改变了我的Sprite的整个颜色,包括矩形周围的线条边框(笔触)。我想只改变矩形内的颜色并保持矩形的边框。我没有在ColorTransform中看到允许我指定lineStyle的属性,所以有不同的方法来改变我的rectagle的填充颜色并保持它周围的边框?

ColorTransform
适用于整个MovieClip
,无论其图形属性中绘制了什么。您可以在每次需要时重绘矩形:
import flash.display.Sprite;
function drawRect(target:Sprite, clr:Number):void{
target.graphics.clear();
target.graphics.beginFill(clr);
target.graphics.lineStyle(1,0x000000);
target.graphics.drawRect(0,0,6,6);
target.graphics.endFill();
}
function changeColor(e:MouseEvent):void{
drawRect(Sprite(e.target), 0x00ffff);
}
function changeColorBack(e:MouseEvent):void{
drawRect(Sprite(e.target), 0xffff00);
}
var rect:Sprite = new Sprite();
rect.addEventListener(MouseEvent.MOUSE_OVER, changeColor);
rect.addEventListener(MouseEvent.MOUSE_OUT, changeColorBack);
this.addChild(rect);
drawRect(rect, 0xffff00);
或者,如果您出于某种原因开始使用ColorTransform
,则可以使用两个单独的Sprites
(外部和内部)构建轮廓矩形并定位内部{{1只有Sprite
