不能统一平衡摩托车

Question

我想平衡摩托车和统一物理。我们可以通过在z轴上冻结旋转来平衡平衡自行车，但这似乎不是很好的.So，我尝试了.This方法平衡自行车很少几秒钟，但出于某种原因，自行车开始在空中跳跃，或有时翻转.I是开放的任何建议。我已经做了一些2d的非物理游戏，但统一物理学是我的新的。在这里输入图像描述

Answer 1

首先，我会停止改变自行车的重心。

然后，我会用自行车来计算扭矩来应用。评论中的解释：

​float adjustFactor = 0.5f; // this value requires tuning

// physics actions should occur in FixedUpdate in most cases
void FixedUpdate()
{    
    // project the bike's local up to the plane perpendicular to the bike's forward
    Vector3 projectedUp = transform.up - Vector3.Dot(transform.forward, _transform.up);

    // find the angle from that projection to global up, around bike forward
    float upOffset = Vector3.SignedAngle(projectedUp, Vector3.up, transform.forward);

    // use angle difference to calculate an adjustment 
    float adjustment = upOffset * adjustFactor;

    // maybe do something else like adjustment = log(adjustment) or adjustment^2 
    //   to change easing of adjustment force. Requires some trial and error 
    //   and further tuning of adjustFactor.

    // Apply adjustment as vector around rb's forward
    _rigidbody.AddRelativeTorque(new Vector3(0f, 0f, adjustment));
}
