40 - C# - 发射子弹 - velocity

作用：发射子弹
其他方法：刚体移动之AddForce()函数
update — 鼠标点击 — 给加速度

代码

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class shoot : MonoBehaviour
{
    public GameObject bullet;
    public float speed = 5; 
    // Start is called before the first frame update
    void Start()
    {
    }
    // Update is called once per frame
    void Update()
    {
        if(Input.GetMouseButtonDown(0))
        {
            GameObject b = GameObject.Instantiate(bullet,transform.position,transform.rotation);
            Rigidbody rgd = b.GetComponent<Rigidbody>();
            rgd.velocity = transform.forward * speed;
        }
    }
}

代码解释

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class shoot : MonoBehaviour
{
    public GameObject bullet;//发射的东西
    public float speed = 5; //速度
    // Start is called before the first frame update
    void Start()
    {
    }
    // Update is called once per frame
    void Update()
    {
        if(Input.GetMouseButtonDown(0))//判断鼠标点击
        {
            GameObject b = GameObject.Instantiate(bullet,transform.position,transform.rotation);//实例化，位置在目标的位置，目标的旋转角度
            Rigidbody rgd = b.GetComponent<Rigidbody>();//获得Rigidbody属性
            rgd.velocity = transform.forward * speed;//设置Rigidbody属性的velocity属性
        }
    }
}

使用

1.把脚本拉到要发射的物体
2.添加要发射子弹
3.注意命名空间这里是shoot
