Unity 3D 中的玩家移动

Question

所以我是 Unity 的新手，我正在关注一个名叫 Brackeys 的 YouTuber，但是当我执行他的角色移动代码时，我的角色不会向前或向后移动，它会向左和向右移动，但速度非常快。我是新手，所以我对此了解不多。这是代码：

using UnityEngine;

public class PlayerMovement：MonoBehaviour {

public Rigidbody rb;

private float forwardForce = 2000f;  
public float sidewaysForce = 500f;  

void FixedUpdate()
{

    rb.AddForce(0, 0, forwardForce * Time.deltaTime);

    if (Input.GetKey("d"))  
    {

        rb.AddForce(sidewaysForce * Time.deltaTime, 0, 0, ForceMode.VelocityChange);
    }

    if (Input.GetKey("a"))  
    {

        rb.AddForce(-sidewaysForce * Time.deltaTime, 0, 0, ForceMode.VelocityChange);
    }

    if (rb.position.y < -1f)
    {
        FindObjectOfType<GameManager>().EndGame();
    }
}

}

Answer 1

我认为你在这里缺少的是沿 z 轴的移动。


    if (Input.GetKey("w"))  
    {

        rb.AddForce(0, 0, forwardForce * Time.deltaTime, ForceMode.VelocityChange);
    }

    if (Input.GetKey("s"))  
    {

        rb.AddForce(0, 0, -forwardForce * Time.deltaTime, ForceMode.VelocityChange);
    }

Answer 2

如果不想让它超速，请更改侧向力：

> public Rigidbody rb; private float forwardForce = 2000f;  // This is
> how fast the player goes forward public float sidewaysForce = 500f; 
> //Change the number here to something lower.

//加上这个可以前进后退

if (Input.GetKey("w"))  
    {

        rb.AddForce(0, 0, forwardForce * Time.deltaTime, ForceMode.VelocityChange);
    }

    if (Input.GetKey("s"))  
    {

        rb.AddForce(0, 0, -forwardForce * Time.deltaTime, ForceMode.VelocityChange);
    }
