刚体Rigidbody.MovePosition控制物体移动

Rigidbody.MovePosition

public void MovePosition(Vector3 position);

Description：

Moves the rigidbody to position.

Use Rigidbody.MovePosition to move a Rigidbody, complying with the Rigidbody's interpolation setting.

If Rigidbody interpolation is enabled on the Rigidbody, calling Rigidbody.MovePosition results in a smooth transition between the two positions in any intermediate frames rendered. This should be used if you want to continuously move a rigidbody in each FixedUpdate.

Set Rigidbody.position instead, if you want to teleport a rigidbody from one position to another, with no intermediate positions being rendered.

例子：

using UnityEngine;
using System.Collections;
public class DemoController : MonoBehaviour {

    public Rigidbody cube1;
    private float speed = 20;
    
    private void Update()
    {
        //cube1.position = cube1.transform.position + Vector3.forward * Time.deltaTime * speed;
        cube1.MovePosition(cube1.transform.position + Vector3.forward * Time.deltaTime * speed);//MovePosition方法使物体移动更平滑
    }
}
