Unity动态修改刚体（Rigidbody）的坐标、旋转冻结状态（constraints）

直接上代码吧：

using UnityEngine;

public class test4: MonoBehaviour {

    private Rigidbody rb;

	private void Awake() 
	{
        rb = gameObject.GetComponent<Rigidbody>();
    }

	private void Start () 
	{
        rb.constraints = RigidbodyConstraints.FreezeRotationY;
	}
}

下面代码可冻结除本项外其他所有：

rb.constraints = ~RigidbodyConstraints.FreezeRotationY;
