I need help with a door script.

I need to make my door a locked door that states it is locked and allow my player to open it only when he has the key, that is in the scene. Below is my door script as of now where my player can open it at will.

using UnityEngine;
using System.Collections;

public class Door : MonoBehaviour {

public GameObject hinge;

Animator anim;

void Start () {
anim = hinge.GetComponent<Animator>();

}

void OnTriggerEnter (Collider entity) {
if (entity.tag == "Player") {
print ("The PlayerMapIcon has entered the OnTriggerEnter.");
}
}

void OnTriggerStay(Collider entity){
if (entity.tag == "Player") {
if(Input.GetKeyUp (KeyCode.E)){
anim.SetBool ("interact", true);
print ("The Player has interacted with the door.");
}
}
}

void OnTriggerExit(Collider entity){
if (entity.tag == "Player") {
print ("The Player has left the trigger.");
}
}
}

 

How many door/key combinations are you looking to support? How are you "holding" the key(s)?

 

Supporting a single key is the easiest. Simply add a public variable to your player script (or make another script like KeyHolder.cs)

Code (csharp):

1.  
2. //in KeyHolder.cs
3. public bool GotKey = false;
4.  
5. OnTriggerEnter(Collider e) {
6.   if(e.tag == "Key") {
7.     GotKey = true;
8.   }
9. }
10.  
11. //in door script
12. if(entity.GetComponent<KeyHolder>.GotKey) {
13.   //he has the key!
14. }
15.
