Unity键盘WASD实现物体移动

本文实例为大家分享了Unity键盘WASD实现物体移动的具体代码，供大家参考，具体内容如下

1首先在场景中建立一个Capsule，将主摄像机拖到其物体下。

2.将脚本挂在Capsule物体下，WASD 控制移动方向，空格延Y轴向上移动，F延Y轴向下移动

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class MoveCam : MonoBehaviour
{
private Vector3 m_camRot;
private Transform m_camTransform;//摄像机Transform
private Transform m_transform;//摄像机父物体Transform
public float m_movSpeed=10;//移动系数
public float m_rotateSpeed=1;//旋转系数
private void Start()
{
m_camTransform = Camera.main.transform;
m_transform = GetComponent<Transform>();
}
private void Update()
{
Control();
}
void Control()
{
if (Input.GetMouseButton(0))
{
 //获取鼠标移动距离
 float rh = Input.GetAxis("Mouse X");
 float rv = Input.GetAxis("Mouse Y");

// 旋转摄像机
 m_camRot.x -= rv * m_rotateSpeed;
 m_camRot.y += rh*m_rotateSpeed;

}

m_camTransform.eulerAngles = m_camRot;

// 使主角的面向方向与摄像机一致
Vector3 camrot = m_camTransform.eulerAngles;
camrot.x = 0; camrot.z = 0;
m_transform.eulerAngles = camrot;

// 定义3个值控制移动
float xm = 0, ym = 0, zm = 0;

//按键盘W向上移动
if (Input.GetKey(KeyCode.W))
{
 zm += m_movSpeed * Time.deltaTime;
}
else if (Input.GetKey(KeyCode.S))//按键盘S向下移动
{
 zm -= m_movSpeed * Time.deltaTime;
}

if (Input.GetKey(KeyCode.A))//按键盘A向左移动
{
 xm -= m_movSpeed * Time.deltaTime;
}
else if (Input.GetKey(KeyCode.D))//按键盘D向右移动
{
 xm += m_movSpeed * Time.deltaTime;
}
if (Input.GetKey(KeyCode.Space) && m_transform.position.y <= 3)
{
 ym+=m_movSpeed * Time.deltaTime;
}
if (Input.GetKey(KeyCode.F) && m_transform.position.y >= 1)
{
 ym -= m_movSpeed * Time.deltaTime;
}
m_transform.Translate(new Vector3(xm,ym,zm),Space.Self);
}
}
