更改高度和宽度时,Flash AS3阴影不会显示

houseXML 具有静态值的变量。我尝试的代码如下:

var mcWhiteBorder:whiteBorder = new whiteBorder();
var dropShadow:DropShadowFilter = new DropShadowFilter();
dropShadow.distance = 1;
dropShadow.alpha = .2;
dropShadow.blurX = 10;
dropShadow.blurY = 10;
mcWhiteBorder.height = 200;
mcWhiteBorder.width = 300;
mcWhiteBorder.x = 50;
mcWhiteBorder.y = 50;
mcWhiteBorder.filters = [dropShadow];

addChild(mcWhiteBorder);

houseXML 并查看您分配的值是否有效等等。

var mcWhiteBorder:whiteBorder = new whiteBorder();
var tmpFilters:Array = mcWhiteBorder.filters;
var dropShadow:DropShadowFilter = new DropShadowFilter();
dropShadow.distance = 1;
dropShadow.alpha = .2;
dropShadow.blurX = 10;
dropShadow.blurY = 10;
mcWhiteBorder.height = houseXML.height-40;
mcWhiteBorder.width = houseXML.width+5;
mcWhiteBorder.x = houseXML.photoX-10;
mcWhiteBorder.y = houseXML.photoY+20;
tmpFilters.push(dropShadow);
mcWhiteBorder.filters = tmpFilters;

addChild(mcWhiteBorder);

filters

请注意,过滤器不适用于大于“特定值”的剪辑,请查看中的评论 this thread ...

在语法方面,我没有看到任何问题。

dropShadow.distance = 1;
dropShadow.alpha = .2;
dropShadow.blurX = 10;
dropShadow.blurY = 10;

那已经相当褪色了。将alpha更改为1或2,看看你是否能看到它。此外,你似乎没有设置颜色。我认为默认值是黑色的。确保你的目标不是在黑暗的东西上,你只是错过了它。
