『功能项目』战士的伤害型技能【45】

我们打开上一篇44战士职业平A怪物掉血的项目，

本章要做的事情是制作技能按钮，点鼠标点击时释放对范围内怪物的伤害技能

首先双击打开资源脚本下的Canvas预制体

制作技能栏

在资源商店中下载免费资源 - 技能图片

将技能图片拖拽至技能栏的Button按钮组件的Image上

对战士动画状态机增加一个技能的动画并创建参数Skill01Trigger

设直线

设置返回线

创建脚本：AttackCtrl.cs

cs 复制代码

using UnityEngine;
using UnityEngine.Events;
//提供机制不提供策略
public class AttackCtrl : MonoBehaviour{
    float hurtTime;
    float endTime;
    float nowTime;
    UnityAction hurtAction;
    UnityAction endAction;
    bool isAttacking = false;
    public void Init() {
        nowTime = 0;
        hurtAction = null;
        endAction = null;
        endTime = 0;
        hurtTime = 0;
        isAttacking = false;
    }
    public bool DoAttack(float hurtTime,float endTime,UnityAction hurtAction,UnityAction endAction) {
        if (isAttacking)
            return false;
        nowTime = 0;
        this.isAttacking = true;
        this.hurtTime = hurtTime;
        this.endTime = endTime;
        this.hurtAction = hurtAction;
        this.endAction = endAction;
        return true;
    }
    void Update() {
        if (isAttacking == false)
            return;
        nowTime += Time.deltaTime;
        if (nowTime >= hurtTime) {
            if (hurtAction != null) {
                //回调
                hurtAction();
                hurtAction = null;
            }
        }
        if (nowTime >= endTime) {
            if (endAction != null) {
                endAction();
                endAction = null;
            }
            this.isAttacking = false;
        }
    }
