巩义网站建设好的推广方式

一： 连招思路

首先人物角色上有三个攻击实例对象 Damage,每一个damage定义了攻击的伤害值，攻击距离，触发器名称，伤害的发起者，攻击持续时间，攻击重置时间，伤害的碰撞框大小等字段：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;[System.Serializable]
public class Damage
{/// <summary>/// 触发动画触发器名称/// </summary>public string animationTrigger = "";/// <summary>/// 组合攻击伤害/// </summary>public int damage = 0;/// <summary>/// 伤害的攻击者/// </summary>public GameObject inflictor;/// <summary>/// 组合攻击持续时间/// </summary>public float duration = 1f;/// <summary>/// 连击重置时间 超过这个时间如果没有收到连击序列 连击将会被取消/// </summary>public float comboResetTime = .5f;[Space(10)][Header("hit collider settings")]public float collSize;public float collDistance;public float collHeight;}

当按下某一个键位的时候，播放对应索引的攻击，如果在攻击时间后再次收到了攻击键位的按下就认为是连击状态，这时候继续播放攻击动作。

二： 代码实现

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class PlayerCombat : MonoBehaviour
{// 主角的攻击组合public Damage[] attackCombo;// 主角的最后一次攻击类型public Damage lastAttack;// 记录最后一次攻击时间public float lastAttackTime;public PlayerController playerController;public CharactorState charactorState;// 最近一次攻击的索引public int attackIndex = 0;// 是否是连击状态public bool continueAttackCombo;void Awake(){playerController = GetComponent<PlayerController>();charactorState = GetComponent<CharactorState>();}public void combatEvent(){Debug.LogWarning("state is " + charactorState.curState);if (charactorState.curState != UnitState.ATTACK){// 是否在攻击窗口内bool insideComboWindow = (lastAttack != null && (Time.time < (lastAttackTime + lastAttack.duration + lastAttack.comboResetTime)));if (insideComboWindow && !continueAttackCombo && attackIndex < attackCombo.Length - 1){// 继续攻击attackIndex++;}else{// 重置攻击attackIndex = 0;}doAttack(attackCombo[attackIndex], UnitState.ATTACK);}if (charactorState.curState == UnitState.ATTACK && !continueAttackCombo && playerController.pc.isGround){if (attackIndex < attackCombo.Length - 1){// 已经处于攻击状态，且不是连续攻击 将连续攻击状态打开continueAttackCombo = true;return;}}}public void doAttack(Damage damage, UnitState state){Debug.Log("animationTrigger is " + damage.animationTrigger);if (damage.animationTrigger == "attack3"){Debug.Log("attack3");}lastAttackTime = Time.time;lastAttack = damage;lastAttack.inflictor = this.gameObject;charactorState.SetState(state);playerController.playerAnimation.setTrigger(damage.animationTrigger);Invoke("Ready", damage.duration);}public void Ready(){Debug.LogWarning("Ready");if (continueAttackCombo){// 重置是否继续连招动作 因为这个时候玩家没有触发攻击动作continueAttackCombo = false;if (attackIndex < attackCombo.Length - 1){attackIndex++;}else{attackIndex = 0;}Debug.LogWarning("连招" + attackCombo[attackIndex].animationTrigger);if (attackCombo[attackIndex] != null && attackCombo[attackIndex].animationTrigger.Length > 0){doAttack(attackCombo[attackIndex], UnitState.ATTACK);}}// 重置玩家状态charactorState.SetState(UnitState.IDLE);}// Update is called once per framevoid Update(){}
}

三：攻击窗口

如果当前主角的状态不是攻击状态，检查是否在攻击时间窗口内，如果在攻击时间窗口内就进行攻击索引的累加，否则攻击索引从0开始

if (charactorState.curState != UnitState.ATTACK){// 是否在攻击窗口内bool insideComboWindow = (lastAttack != null && (Time.time < (lastAttackTime + lastAttack.duration + lastAttack.comboResetTime)));if (insideComboWindow && !continueAttackCombo && attackIndex < attackCombo.Length - 1){// 继续攻击attackIndex++;}else{// 重置攻击attackIndex = 0;}doAttack(attackCombo[attackIndex], UnitState.ATTACK);}if (charactorState.curState == UnitState.ATTACK && !continueAttackCombo && playerController.pc.isGround){if (attackIndex < attackCombo.Length - 1){// 已经处于攻击状态，且不是连续攻击 将连续攻击状态打开continueAttackCombo = true;return;}}
