我的这款游戏仍然在开发中。到目前为止,我的移动代码可以使用箭头键移动播放器。我还具有使用鼠标移动播放器的功能。它将使播放器了解其面对的方式。假设玩家朝左。如果我单击向上箭头键,它仍会向前移动。我想将播放器朝其面对的方向移动。
代码:
using System.Collections.Generic;
using UnityEngine;
public class PlayerMovement : MonoBehaviour {
public float distance = 5f;
public Transform playerCam;
void FixedUpdate () {
transform.localEulerAngles = new Vector3(transform.localEulerAngles.x,
Camera.main.transform.localEulerAngles.y, transform.localEulerAngles.z);
if (Input.GetKey(KeyCode.LeftArrow))
{
Vector3 position = this.transform.position;
position.x--;
this.transform.position = position;
}
if (Input.GetKey(KeyCode.RightArrow))
{
Vector3 position = this.transform.position;
position.x++;
this.transform.position = position;
}
if (Input.GetKey(KeyCode.UpArrow))
{
Vector3 position = this.transform.position;
position.z++;
this.transform.position = position;
}
if (Input.GetKey(KeyCode.DownArrow))
{
Vector3 position = this.transform.position;
position.z--;
this.transform.position = position;
}
if (Input.GetKey("W"))
{
Vector3 position = this.transform.position;
position.z++;
this.transform.position = position;
}
if (Input.GetKey("S"))
{
Vector3 position = this.transform.position;
position.z--;
this.transform.position = position;
}
if (Input.GetKey("A"))
{
Vector3 position = this.transform.position;
position.x--;
this.transform.position = position;
}
if (Input.GetKey("D"))
{
Vector3 position = this.transform.position;
position.x++;
this.transform.position = position;
}
}
}

使用transform.forward
获取玩家面对的方向。
它始终是一个单位矢量,因此,如果您只想在玩家的前进方向上将位置移动一个单位,则只需将其添加到transform.position
:
if (Input.GetKey("W"))
{
this.transform.position += this.transform.forward;
}
