unity官方demo学习之Stealth（十五）单开门动画

1，将modles中的door_generic_slide拖入层级视图，位置：-6,0,7；角度：90.子对象勾选 use light probes使光可以照到门
2，父对象添加Sphere collider使门可以检测到敌人或玩家的靠近，center：y：1，radius：3，勾选 Is Trigger ；子对象添加box collider，不用调整
3，为门添加开关动画，将DoneSingleDoorAnimator拖动到Collider里，取消Apply Root Motion（如果要自己制作该动画的话，
将modles中的door_generic_slide下的close先拖进去（因为默认状态使关闭），再拖进open，添加bool类型参数Open，设置close与open之间的转换
条件是Open参数，为使动画更平滑，分别拖动两条线到150%）
4，门移动过程中，碰撞器也在移动，所以要为其添加刚体组件，但不能让他影响碰撞，所以勾选Is Kinematic，取消 use Gravity。门要播放音效，添加Audio->audio source组件

5，为门添加脚本DoneDoorAnimation控制门的开关

using UnityEngine;using System.Collections;public class DoneDoorAnimation : MonoBehaviour{public bool requireKey;// Whether or not a key is required.public AudioClip doorSwishClip;// Clip to play when the doors open or close.public AudioClip accessDeniedClip;// Clip to play when the player doesn't have the key for the door.private Animator anim;// Reference to the animator component.private DoneHashIDs hash;// Reference to the HashIDs script.private GameObject player;// Reference to the player GameObject.private DonePlayerInventory playerInventory;// Reference to the PlayerInventory script.private int count;// The number of colliders present that should open the doors.void Awake (){// Setting up the references.anim = GetComponent<Animator>();hash = GameObject.FindGameObjectWithTag(DoneTags.gameController).GetComponent<DoneHashIDs>();player = GameObject.FindGameObjectWithTag(DoneTags.player);playerInventory = player.GetComponent<DonePlayerInventory>();}void OnTriggerEnter (Collider other){// If the triggering gameobject is the player...if(other.gameObject == player){// ... if this door requires a key...if(requireKey){// ... if the player has the key...if(playerInventory.hasKey)// ... increase the count of triggering objects.count++;else{// If the player doesn't have the key play the access denied audio clip.audio.clip = accessDeniedClip;audio.Play();}}else// If the door doesn't require a key, increase the count of triggering objects.count++;}// If the triggering gameobject is an enemy...else if(other.gameObject.tag == DoneTags.enemy){// ... if the triggering collider is a capsule collider...if(other is CapsuleCollider)// ... increase the count of triggering objects.count++;}}void OnTriggerExit (Collider other){// If the leaving gameobject is the player or an enemy and the collider is a capsule collider...if(other.gameObject == player || (other.gameObject.tag == DoneTags.enemy && other is CapsuleCollider))// decrease the count of triggering objects.count = Mathf.Max(0, count-1);}void Update (){// Set the open parameter.anim.SetBool(hash.openBool,count > 0);// If the door is opening or closing...if(anim.IsInTransition(0) && !audio.isPlaying){// ... play the door swish audio clip.audio.clip = doorSwishClip;audio.Play();}}}

参数：（公有）判断门打开是否需要钥匙（单门需要，电梯的双门不需要）
门打开或关闭时的音效
玩家没有钥匙时门播放音效
（私有）
动作控制器引用
HashID脚本引用
玩家对象引用
玩家财产脚本引用
用来计数门触发器周围的碰撞数目（来决定门的开关）
函数：  Awake
获取参数中创建的4个引用



OnTriggerEnter (Collider other)进入触发器时触发
如果碰撞对象是玩家
门是否需要钥匙
如果玩家有钥匙
计数++（门可以打开）
玩家没钥匙
设置音频剪辑为accessDeniedClip
播放一次没钥匙时的音效
门不需要钥匙
计数++
如果碰撞对象时敌人
如果碰撞到敌人的CapsuleCollider（用is关键字来判断）
计数++




OnTriggerExit (Collider other)离开触发器时触发
离开的是玩家或敌人的CapsuleCollider
计数器返回0  count = Mathf.Max(0, count-1);




Update
根据计数器返回Open的bool值
如果门在移动且没有播放音效（0代表base layer）
设置音频剪辑为doorSwishClip
播放一次该音频剪辑




6，将door_open,door_accessDenied 分别拖入Door Swish Clip和Access Denied Clip
7，将门door_generic_slide制作成prefab
8，Ctrl+d复制一个，位置-15.9,0,7； 再一个，-7.9,0.37,；
