物理对象在Unity中无法以低速正确反弹 [英] Physics object doesn't bounce correctly at low speed in Unity

问题描述

我遇到了一个问题，当启用物理的球缓慢移动时，它无法正确地弹开物体.我拍了一段视频来说明问题

https://youtu.be/9T1hkir7sCo

基本上，球应该碰到静止的球，静止的球应该弹起.当速度足够快但在阈值以下时，它们都开始一起移动，这看起来很奇怪，这可以起作用.

这是怎么回事，如何使它正确反应?

实验细节(两个对象都相同):

RigidBody

• 质量:1
• 拖动:0
• 角向阻力:0
• 使用重力:false

物理材料:

• 动摩擦:0
• 静摩擦:0
• 弹跳:1

解决方案

Unity的默认设置 Bounce Threshold 用于识别跳动的是速度> 2

设置速度值.如果两个碰撞对象的相对速度低于此值，则它们不会相互反弹.此值还可以减少抖动，因此不建议将其设置为非常低的值.

您可以在PhysicsManager(编辑-> 项目设置-> 物理)中更改此Bounce Threshold:

或在运行时通过脚本(请参见 Physics.bounceThreshold )

Physics.bounceThreshold = 1;

---

根据需要将其缩小...但是请注意

此值还可以减少抖动，因此不建议将其设置为非常低的值.

I am running into a problem where when a physics enabled ball is going slowly it doesn't bounce off objects correctly. I have made a video to illustrate the problem

https://youtu.be/9T1hkir7sCo

Basically, the ball should run into the stationary ball and the stationary one should bounce off. This works when the speed is fast enough, but below a threshold they both just start moving together, which looks weird.

Whats going with this, and how can I make it react properly?

Experiment details (same for both objects):

RigidBody

• Mass: 1
• Drag: 0
• Angular Drag: 0
• Use gravity: false

Physics material:

• Dynamic friction: 0
• Static friction: 0
• Bounciness: 1

解决方案

Unity's default Bounce Threshold for recognizing bounces is a velocity > 2

Set a velocity value. If two colliding objects have a relative velocity below this value, they do not bounce off each other. This value also reduces jitter, so it is not recommended to set it to a very low value.

You can change this Bounce Threshold in the PhysicsManager (Edit->Project Settings->Physics):

or via script on runtime (see Physics.bounceThreshold)

Physics.bounceThreshold = 1;

---

Make it as small as you need it ... but note

This value also reduces jitter, so it is not recommended to set it to a very low value.
