使用 Android 物理引擎创建光滑的绳子
我想用（流行的）android 物理引擎（AndEngine 和 libgdx）练习编程。
用物理对象创建一个小世界并不是很困难，但现在我想创建一根绳子并将其连接到世界中的对象。
有多种方法可以做到这一点，例如：

但我想看到一条光滑的绳子，就像 Android 和 IOS 上的“割绳子”游戏一样。
有什么想法可以做到这一点吗？我还找不到答案，但我认为这将创建许多捆绑在一起的较小对象，但我认为这在性能方面会很糟糕？
I want to practice programming with (popular) android physics engines (AndEngine and libgdx).
It is not very difficult to create a small world with physics objects but now I want to create a rope and connect it to objects in the world.
There are several ways to do it, for example:

But I want to see a smooth rope like in "Cut The Rope" game on Android and IOS.
Are there any ideas how to do this? I can't find answer yet but I think it would be to create a number of smaller objects tied together but I think this would be bad performance-wise?

我相信您创建较短的绳段并用关节连接它们的本能是正确的，是的，您最终为一段绳子创建的实体数量会对性能产生影响。
要了解它是否适合您的特定情况，我建议创建一根具有可变长度段的绳索，并根据性能基准做出决定，以确定通过增加段数可以使绳索变得多么光滑。
I believe your instinct to create shorter segments with joints connecting them is correct and yes, the number of bodies you end up creating for a length of rope will have an effect on the performance.
To know whether it will work for your particular situation, I would suggest creating a rope with variable length segments and make a decision based off benchmarking the performance as to how smooth you can make the rope by increasing the number of segments.
在 ios 上，我们基于此示例 http://www.cocos2d-iphone.org/archives /1112 ，我们现在正在尝试将其移植到android上，但是我们的box2d版本还不支持绳索关节。
On ios we based our rope on this example, http://www.cocos2d-iphone.org/archives/1112 , we are now trying to port it to android, but our version of the box2d does not support the rope joint yet.
