『功能项目』技能释放【08】

本文主要是介绍『功能项目』技能释放【08】，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

我们打开上一篇07摄像机跟随角色的项目，

本章要做的事情是主角按F按键释放技能，按E键切换技能类型的功能。

首先创建一个空文件夹Resources

创建一个球体Shpere

修改球体缩放尺寸

创建一个材质Material

将材质重命名为Yellow，色板调至为黄色

将Yellow材质球拖拽至球体Shpere对象身上

设置一个新输入系统

拖拽一个攻击动画

连线

创建一个参数

设直线

创建脚本代码：MagicBall.cs

脚本绑定在Resources文件下的Sphere预制体

using UnityEngine;
public class MagicBall : MonoBehaviour{
float speed = 10.0f;
public float lifeTime = 2;
float startTime;
void Start(){
transform.position = new Vector3(transform.position.x,
transform.position.y + 1f, transform.position.z);
startTime = Time.time;
}
void Update(){
transform.position += speed * transform.forward * Time.deltaTime;
if (startTime + lifeTime < Time.time)
Destroy(gameObject);
}
void OnTriggerEnter(Collider other){
//稍后补充碰撞逻辑
}
}

创建脚本：SkillRelease.cs

using UnityEngine;
using System.Collections;
public class SkillRelease : MonoBehaviour{
GameObject prefabBall;
float straightSkillCD = 0.2f;
float sectorSkillCD = 0.5f;
float lastShootTime;
int curSkill { get; set; }
void Awake(){
prefabBall = Resources.Load<GameObject>("Sphere");
}
public void Release(bool keyDown, bool keyPressed){
switch (curSkill){
case 0:
if (keyDown)
StartCoroutine(DelayedPistolFire(0.5f));
break;
case 1:
if (keyDown)
StartCoroutine(DelayedShotgunFire(0.5f));
break;
}
}
public int Change(){
curSkill += 1;
if (curSkill == 3)
curSkill = 0;
return curSkill;
}
void StraightSkill(){
if (lastShootTime + straightSkillCD > Time.time)
return;
lastShootTime = Time.time;
GameObject sphere = Instantiate(prefabBall, null);
sphere.transform.position = transform.position + transform.forward * 2.0f;
sphere.transform.forward = transform.forward;
}
void SectorSkill(){
if (lastShootTime + sectorSkillCD > Time.time)
return;
lastShootTime = Time.time;
for (int i = -2; i <= 2; i++){
GameObject sphere = Instantiate(prefabBall, null);
Vector3 dir = Quaternion.Euler(0, i * 10, 0) * transform.forward;
sphere.transform.position = transform.position + dir * 2.0f;
sphere.transform.forward = dir;
MagicBall ball = sphere.GetComponent<MagicBall>();
ball.lifeTime = 1f;
}
}
IEnumerator DelayedPistolFire(float delay){
yield return new WaitForSeconds(delay);
StraightSkill();
}
IEnumerator DelayedShotgunFire(float delay){
yield return new WaitForSeconds(delay);
SectorSkill();
}
}
将代码绑定在主角常态身上
