Unity3d:仅将幅度钳位到x轴

Question

使用Unity3d 4.1.2,C#mono.

转到以下脚本:

using UnityEngine;
using System.Collections;

public class PlayerMove : MonoBehaviour 
{
public float MoveSpeed = 30.0f;

public float maxVel = 0.000000001f;
// Use this for initialization
void Start () 
{
    //Physics.gravity = Vector3(0,-50,0);
}

void FixedUpdate()
{
    maxVel = 20f;
    MoveSpeed = 50.0f;
    if(Input.GetKey(KeyCode.D))
    {
        rigidbody.AddForce(Vector3.right * MoveSpeed);
        Debug.Log("BEFORE = " + rigidbody.velocity.magnitude);
    }

    if(Input.GetKey(KeyCode.A))
    {
        rigidbody.AddForce(Vector3.left * MoveSpeed);
    }

    rigidbody.velocity = Vector3.ClampMagnitude(rigidbody.velocity, maxVel);
    Debug.Log("AFTER = " + rigidbody.velocity.magnitude);
}
// Update is called once per frame
void Update () 
{

}
}

你可以看到工作正常,夹具有一些问题,但最终让它工作.

有一个问题......

在Unity的物理引擎中,我将y值更改为-30,并将材料"反弹"设置为1,因此它不会消耗能量.

问题是我的夹具是夹紧回弹效应,因为夹具影响所有轴:(因此刚体永远不会返回到它的y位置.

有没有办法改变夹子只影响x轴？我一直无法找到任何相关信息.

欢呼的家伙

是的,只夹x值:

Vector3 clampVel = rigidBody.velocity;
clampVel.x = Mathf.Clamp(clampVel.x, min, max);

rigidBody.velocity = clampVel;
