相对于变换原点的质心。
如果未在脚本中设置质心,则根据附加到刚体的所有碰撞体自动计算。如果设置了自定义质心,则修改(例如添加或移除碰撞体、对碰撞体进行转换、缩放等)后不再自动重新计算质心。要恢复为自动计算质心,请使用 Rigidbody.ResetCenterOfMass。
在模拟汽车时,设置质心通常可让其更加稳定。
质心较低的汽车不太容易翻车。
注意:centerOfMass
相对于变换的位置和旋转,但不反映变换的缩放!
// Expose center of mass to allow it to be set from // the inspector. using UnityEngine; using System.Collections;
public class ExampleClass : MonoBehaviour { public Vector3 com; public Rigidbody rb;
void Start() { rb = GetComponent<Rigidbody>(); rb.centerOfMass = com; } }
