您可以遍历每一帧,而无需等待动画播放:
假设您的剪辑被称为bob
:
var lifetimeBounds:Rectangle = new Rectangle();
bob.gotoAndStop(1);
for(var i:int=1;i<=bob.totalFrames;i++){
lifetimeBounds.width = Math.max(lifetimeBounds.width, bob.width);
lifetimeBounds.height = Math.max(lifetimeBounds.height, bob.height);
lifetimeBounds.x = Math.min(lifetimeBounds.x, bob.x);
lifetimeBounds.y = Math.min(lifetimeBounds.y, bob.y);
bob.nextFrame();
}
bob.gotoAndStop(1); //reset bob back to the beginning
它会增加 CPU 负担(因此,如果上述方法适用于您的情况,我建议不要使用它),但您也可以getBounds()
在上面的示例中使用并将返回的矩形与 lifeBounds 矩形进行比较:
var tempRect:Rectangle;
var lifetimeBounds:Rectangle = new Rectangle();
bob.gotoAndStop(1);
for(var i:int=1;i<=bob.totalFrames;i++){
tmpRect = bob.getBounds(this);
lifetimeBounds.width = Math.max(lifetimeBounds.width, tempRect.width);
lifetimeBounds.height = Math.max(lifetimeBounds.height, tempRect.height);
lifetimeBounds.x = Math.min(lifetimeBounds.x, tempRect.x);
lifetimeBounds.y = Math.min(lifetimeBounds.y, tempRect.y);
bob.nextFrame();
}
