更改Box2D锚点？ [英] Change Box2D Anchor Point?

问题描述

在Cocos2D中，我创建锚点为（0,1）的CCSprite，这与UIKit的方式类似。无论如何，我正在尝试在Box2D中更改锚点，这可能吗？
如果是这样，我将如何以（0,1）的锚点进行操作？

In Cocos2D I am creating my CCSprites with anchor points of (0,1) which is similar to the way UIKit does it. Anyway, I am trying to change the anchor point in Box2D, is this possible? If so how would I do it with an anchor point of (0,1)?

谢谢！

推荐答案

Box2D实体没有锚点。

Box2D bodies don't have an anchor point.

anchorPoint是节点纹理相对于节点位置的偏移量。 Box2D实体没有纹理，因此没有锚点。

The anchorPoint is an offset of a node's texture relative to the node's position. Box2D bodies don't have a texture, hence no anchor point.

通常来说，将anchorPoint的默认位置更改为0.5,0.5会使很多事情变得更加困难。例如，导致您问这个问题的问题。

Generally speaking you're going to make a lot of things more difficult by changing the anchorPoint from its default 0.5,0.5 position. Like, for example, the issue that lead you to ask this very question.
