控制该刚体的模拟自由度。
默认情况下,该属性设置为 RigidbodyConstraints.None - 允许沿所有轴旋转和移动。
在某些情况下,您可能需要限制 Rigidbody 只能沿某些轴移动或旋转,
例如在开发 2D 游戏时。可以使用按位 OR 运算符组合多个
约束。
注意,位置约束应用于世界空间,旋转约束应用于本地空间。
//Attach this script to a GameObject. //Attach a Rigidbody to the GameObject by clicking the GameObject in the Hierarchy and //clicking the Add Component button. Search for Rigidbody in the field and select //it when shown.
using UnityEngine;
public class Example : MonoBehaviour { Rigidbody m_Rigidbody;
void Start() { m_Rigidbody = GetComponent<Rigidbody>(); //This locks the RigidBody so that it does not move or rotate in the Z axis. m_Rigidbody.constraints = RigidbodyConstraints.FreezePositionZ | RigidbodyConstraints.FreezeRotationZ; } }
