Open/close door when the player is close to it.

I set up a script that allows me to open/close doors by dragging the mouse up and down and it works right. However what I want to achieve is that the player can only open/close doors when he is near the door.

The code is the following:

Code (CSharp):

1.  
2. public class door : MonoBehaviour
3. {
4.     public float ySensitivity = 300f;
5.     public float frontOpenPosLimit = 45;
6.     public float backOpenPosLimit = 45;
7.     public GameObject frontDoorCollider;
8.     public GameObject backDoorCollider;
9.     bool moveDoor = false;
10.     DoorCollision doorCollision = DoorCollision.NONE;
11.     // Use this for initialization
12.     void Start()
13.     {
14.         StartCoroutine(doorMover());
15.     }
16.     // Update is called once per frame
17.     void Update()
18.     {
19.         if (Input.GetMouseButtonDown(0))
20.         {
21.             Debug.Log("Mouse down");
22.             RaycastHit hitInfo = new RaycastHit();
23.             if (Physics.Raycast(Camera.main.ScreenPointToRay(Input.mousePosition), out hitInfo))
24.             {
25.                 if (hitInfo.collider.gameObject == frontDoorCollider)
26.                 {
27.                     moveDoor = true;
28.                     Debug.Log("Front door hit");
29.                     doorCollision = DoorCollision.FRONT;
30.                 }
31.                 else if (hitInfo.collider.gameObject == backDoorCollider)
32.                 {
33.                     moveDoor = true;
34.                     Debug.Log("Back door hit");
35.                     doorCollision = DoorCollision.BACK;
36.                 }
37.                 else
38.                 {
39.                     doorCollision = DoorCollision.NONE;
40.                 }
41.             }
42.         }
43.         if (Input.GetMouseButtonUp(0))
44.         {
45.             moveDoor = false;
46.             Debug.Log("Mouse up");
47.         }
48.     }
49.     IEnumerator doorMover()
50.     {
51.         bool stoppedBefore = false;
52.         float yRot = 0;
53.         while (true)
54.         {
55.             if (moveDoor)
56.             {
57.                 stoppedBefore = false;
58.                 Debug.Log("Moving Door");
59.                 yRot += Input.GetAxis("Mouse Y") * ySensitivity * Time.deltaTime;
60.                 //Check if this is front door or back
61.                 if (doorCollision == DoorCollision.FRONT)
62.                 {
63.                     Debug.Log("Pull Down(PULL TOWARDS)");
64.                     yRot = Mathf.Clamp(yRot, -frontOpenPosLimit, 0);
65.                     Debug.Log(yRot);
66.                     transform.localEulerAngles = new Vector3(0, -yRot, 0);
67.                 }
68.                 else if (doorCollision == DoorCollision.BACK)
69.                 {
70.                     Debug.Log("Pull Up(PUSH AWAY)");
71.                     yRot = Mathf.Clamp(yRot, 0, backOpenPosLimit);
72.                     Debug.Log(yRot);
73.                     transform.localEulerAngles = new Vector3(0, yRot, 0);
74.                 }
75.             }
76.             else
77.             {
78.                 if (!stoppedBefore)
79.                 {
80.                     stoppedBefore = true;
81.                     Debug.Log("Stopped Moving Door");
82.                 }
83.             }
84.             yield return null;
85.         }
86.     }
87.     enum DoorCollision
88.     {
89.         NONE, FRONT, BACK
90.     }
91. }
92.  

Right now I can open/close doors when the player is at any distance. How can I achieve for the player to open/close doors when he is near to it? some sort of triggers?

 

Definitely a very common approach.



NOTE: some of those tutorials may be auto-open. Your job is to isolate the condition that determines "I am close" via trigger, and connect it to your current on-demand open.

 

Update: So I set up this code for the trigger collider:

Code (CSharp):

1. public class triggerDoor : MonoBehaviour
2. {
3.  
4.  
5.     void OnTriggerEnter(Collider other)
6.     {
7.         // enable script on GameObject when player enters trigger
8.         GetComponentInChildren<door>().enabled = true;
9.     }
10.     void OnTriggerExit(Collider other)
11.         {
12.         // disable script on GameObject when player enters trigger
13.         GetComponentInChildren<door>().enabled = false;
14.         }
15. }
16.  

It works at some extent. Because when I'm in a certain position I can close/open the door without clicking. It gets sort of stuck and when I move the mouse up and down the door opens and closes, no matter if I click or not.

 

Nevermind. I changed it for .moveDoor = false;
