Question

我正在尝试绘制一个用圆圈遮罩的对象，但应用的蒙版更像是一个圆圈的边界矩形

我尝试使用drawCircle方法绘制的圆圈：

private function squareToRound(ability:MovieClip):MovieClip
{
    var container:MovieClip = new MovieClip();
    var newAbility:MovieClip = ability;
    var newMask:MovieClip = new MovieClip();

    newAbility.width = 43;
    newAbility.height = 43;
    newMask.x = newAbility.x + newAbility.width / 2;
    newMask.y = newAbility.y + newAbility.height / 2;

    container.addChild(newAbility);
    newMask.graphics.beginFill();
    newMask.graphics.drawCircle(0, 0, 8);
    newMask.graphics.endFill();
    container.addChild(newMask);

    newAbility.mask = newMask;
    return container;
}

......作为SWF的资产：

private function squareToRound(ability:MovieClip):MovieClip
{
    var container:MovieClip = new MovieClip();
    var newAbility:MovieClip = ability;
    var newMask:MovieClip = new CircleAbilityMask();

    newAbility.width = 43;
    newAbility.height = 43;
    newMask.x = newAbility.x + newAbility.width / 2;
    newMask.y = newAbility.y + newAbility.height / 2;

    container.addChild(newAbility);
    container.addChild(newMask);

    newAbility.mask = newMask;
    return container;
}

结果是平等的。

我通过评论“newAbility.mask = newMask;”检查了掩码的样子。线

这应该在当前的OpenFL版本中解决：

https://github.com/openfl/openfl/blob/develop/CHANGELOG.md#650-11102017

您还可以使用Cairo（在本机平台上）或Canvas（在HTML5上）获得更流畅/更好的屏蔽支持：

openfl test html5 -Dcanvas
openfl test windows -Dcairo

当您bitmapData.draw，sprite.cacheAsBitmap = true或其他触发软件渲染而不是GL的API时，也会使用这些。

圆形遮罩就像矩形一样
