如何计算精灵的大小? [英] How to calculate the size of a sprite?

问题描述

我有一个精灵，我可以在其中进行一些自定义绘图，但我希望容器知道将精灵正确放置在何处.为此，容器需要知道精灵有多大.UIComponents 会经历一个测量阶段，但 sprite 不会.如何计算精灵的大小?

I have a sprite that I do some custom drawing in, but I would like the container to know where to position the sprite properly. To do this, the container needs to know how big the sprite is. UIComponents go through a measure stage, but sprites don't . How do I calculate the size that a sprite will be?

我正在 Event.ENTER_FRAME 中进行绘图，而且它是动画的，所以我无法提前知道它会有多大.UIComponent 有一个 measure 函数，我想创建类似的东西.

I'm doing the drawing in Event.ENTER_FRAME, and it's animated, so I can't tell ahead of time how big it's going to be. The UIComponent has a measure function and I'd like to create something similar.

推荐答案

据我所知，确切的答案是，您无法提前知道，您必须实际绘制精灵以确定其大小.

The precise answer, as far as I can gather is, you can't tell ahead of time, you must actually draw into the sprite to determine it's size.
