實作

角色攻擊

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class playcontrol : MonoBehaviour
{
  public GameObject knife;//生成的物件
  void Update()
    {
     if(Input.GetKeyDown(KeyCode.E))
        {
            Instantiate(knife,this.transform.position,Quaternion.identity);//生成飛刀
        }
  }
}

飛刀射擊

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class knifecontrol : MonoBehaviour
{
    public float timer=0;
    void Start()
    {

    }
    void Update()
    {
        this.gameObject.transform.position += new Vector3(Time.deltaTime * 60, 0, 0);//向右飛行
        timer -= Time.deltaTime;
        if (timer <= 0)
        {
            Destroy(this.gameObject);//刪除物件
        }
    }
}
