bepuphysics1制作一个台球游戏测试物理效果

[hujiangang]

1.我不知为什么，启动的时候所有的球一直在抖动？
2.无论我怎么调参数，效果都非常差，比如撞击库边完全不符合实际效果，用 Unity PhyX效果是正确的，只是我想把物理部分放到服务器；

Quick guess since I don't have time at the moment to do a deeper dive: this sounds like the involved shapes and gravity imply a scale that is mismatched with the default tuning of the simulation. Bepuphysics1, unlike bepuphysics2, is quite scale sensitive. See the configurationhelper.applyscale function: https://github.com/bepu/bepuphysics1/blob/master/BEPUphysicsDemos/ConfigurationHelper.cs#L137

If not that, I'd be suspicious of the timestep being either variable, or far too large for the simulation. If that's the case, using more frequent timesteps with a smaller, constant timestep duration would help.

In the future, please stick bepuphysics1 questions over on the bepuphysics1 repo: https://github.com/bepu/bepuphysics1, thanks!

Attempt at a translation:
由于目前没有时间深入研究，先做一个初步猜测：听起来像是所涉及的形状和重力所隐含的尺度与模拟的默认调优参数不匹配。与 bepuphysics2 不同，bepuphysics1 对尺度非常敏感。请参阅 ConfigurationHelper.ApplyScale 函数：https://github.com/bepu/bepuphysics1/blob/master/BEPUphysicsDemos/ConfigurationHelper.cs#L137
如果不是这个原因，我怀疑可能是时间步长的问题——要么是时间步长不固定（可变的），要么是对于该模拟来说步长过大。如果是这种情况，使用更频繁的、更小的固定时间步长会有所帮助。
另外，以后请将 bepuphysics1 相关的问题发到 bepuphysics1 的仓库：https://github.com/bepu/bepuphysics1, 谢谢!
