Unity3D 5.x 交互功能 - 碰撞檢測函數

1，給第一人稱控制器添加腳本：playercollisions.js 腳本中只定義變量，先不添加方法：

#pragma strict

var door_open_time:float=3.0;
var door_open_sound:AudioClip;
var door_shut_sound:AudioClip;

private var doorisopen:boolean=false;
private var doortimer:float=0.0;
private var currentdoor:GameObject;
 

2，給playercollisions.js中的變量指定對象：

　　

3，然后添加碰撞觸發執行的方法：

function OnControllerColliderHit(hit:ControllerColliderHit){ 
    if (hit.gameObject.tag=="playerDoor" && doorisopen==false) { 
        opendoor(hit.gameObject); 
    }
}
 
    function opendoor(door:GameObject){ 
        doorisopen=true; 
        door.GetComponent(AudioSource).PlayOneShot(door_open_sound);
        door.transform.parent.GetComponent(Animation).Play();
    }

4，確定碰撞對象已經添加Collider碰撞組件，規則物體（Cube）添加Box Collider，不規則物體添加Mesh Collider:

　  

　　我們給Door添加Box Collider並增大Size Y ，方便碰撞操作：

　　

5，處理碰撞的時候，可以借助 print((hit.gameObject); 查看當前碰撞的對象是什么

　　是 Door 還是 OutPost:

　　

6，判斷 hit.gameObject.tag=="playerDoor" 的時候，要保證大小寫一致

　　

7，播放開門動畫的時候，注意教程中outPost和自己項目中outPost的Animations的區別：

　　教程中的動畫進行了分割，而自己項目中的動畫沒有，所以我們只播放一次：

 door.transform.parent.GetComponent(Animation).Play();

　　------

8，5.x版本中的播放方法：

door.GetComponent(AudioSource).PlayOneShot(door_open_sound);

9，碰撞開門，播放聲音的JS代碼,添加到第一人稱后，即可實現碰撞開門、播放開門聲音：

#pragma strict

var door_open_time:float=3.0;
var door_open_sound:AudioClip;
var door_shut_sound:AudioClip;

private var doorisopen:boolean=false;
private var doortimer:float=0.0;
private var currentdoor:GameObject;
 

function OnControllerColliderHit(hit:ControllerColliderHit){  
    print(hit.gameObject);
    if (hit.gameObject.tag=="playerDoor" && doorisopen==false) { 
        opendoor(hit.gameObject); 
    }
} 
    function opendoor(door:GameObject){ 
        doorisopen=true; 
        door.GetComponent(AudioSource).PlayOneShot(door_open_sound);
        door.transform.parent.GetComponent(Animation).Play();
    }

 10，加入關門方法，3秒后再次播放動畫：

#pragma strict

var door_open_time:float=3.0;
var door_open_sound:AudioClip;
var door_shut_sound:AudioClip;

private var doorisopen:boolean=false;
private var doortimer:float=0.0;
private var currentdoor:GameObject;
private var currentDoor:GameObject;
 
     function Start(){ 
    }

     function Update(){ 
     //如果門打開，開始計時  超過3秒后 再吃執行動畫，並把開門時間重置為0
             if(doorisopen==true){ 
                 doortimer+=Time.deltaTime; 
                       print(doortimer);
                if(doortimer>door_open_time){
                    doortimer=0;
                    shutdoor(currentDoor); 
                }
         }
    }

    //檢測碰撞
function OnControllerColliderHit(hit:ControllerColliderHit){  
    print(hit.gameObject);
    if (hit.gameObject.tag=="playerDoor" && doorisopen==false) { 
            currentDoor=hit.gameObject;
        opendoor(hit.gameObject);  
    }
} 

   // //開門
    function opendoor(door:GameObject){ 
        doorisopen=true; 
        door.GetComponent(AudioSource).PlayOneShot(door_open_sound);
        door.transform.parent.GetComponent(Animation).Play();
    }
    // 關門
   function shutdoor(door:GameObject){ 
        doorisopen=false;  
        door.GetComponent(AudioSource).PlayOneShot(door_shut_sound);
        door.transform.parent.GetComponent(Animation).Play();
    }

11，整合開門、關門方法：

#pragma strict

var door_open_time:float=3.0;
var door_open_sound:AudioClip;
var door_shut_sound:AudioClip;

private var doorisopen:boolean=false;
private var doortimer:float=0.0;
private var currentdoor:GameObject;
private var currentDoor:GameObject;
 
     function Start(){ 
    }

     function Update(){ 
     //如果門打開，開始計時  超過3秒后 再吃執行動畫，並把開門時間重置為0
             if(doorisopen==true){ 
                 doortimer+=Time.deltaTime; 
                       print(doortimer);
                if(doortimer>door_open_time){
                    doortimer=0;
                    //shutdoor(currentDoor); 
                    door(currentDoor,false,door_shut_sound,"closedoor");
                }
         }
    }

    //檢測碰撞
function OnControllerColliderHit(hit:ControllerColliderHit){  
    print(hit.gameObject);
    if (hit.gameObject.tag=="playerDoor" && doorisopen==false) { 
            currentDoor=hit.gameObject;
        //opendoor(hit.gameObject);  
        door(currentDoor,true,door_open_sound,"opendoor");
    }
}   

   //對象，門的狀態，播放的聲音，播放的對象
    function door(thisDoor:GameObject,doorOpenOrClose:boolean,audio_clip:AudioClip,ani_name:String){ 
        doorisopen=doorOpenOrClose;
        thisDoor.GetComponent(AudioSource).PlayOneShot(audio_clip);
        thisDoor.transform.parent.GetComponent(Animation).Play(); //播放動畫 區分開門和關門
    }
