How to make a door stay open if the player is inside the trigger zone?

Question

I've been struggling with this for all day long, I want to make a door to stay open when the player is inside the trigger zone, but I cannot make it happen...

Here is what I did:

• A basic animations and animator (Open, Close, Idle/Default)
• Default transitions between states (with and without "Exit Time")

• A basic script to check if the player is inside the trigger:

  using System.Collections;
  using System.Collections.Generic;
  using UnityEngine;
  
  public class DoorScript : MonoBehaviour 
  {
      Animator _animator;
      bool doorOpen;
  
  // Use this for initialization
  void Start () 
  {
      doorOpen = false;
      _animator = GetComponent<Animator>();
  }
  
  /* // Update is called once per frame
  void Update () 
  {
  
  } */
  
  void OnTriggerEnter(Collider other)
  {
      if (other.tag == "Player")
      {
          doorOpen = true;
          DoorController("isOpen");
      }
  }
  
  void OnTriggerExit(Collider other)
  {
      if (other.tag == "Player")
      {
          doorOpen = false;
          DoorController("isClosed");
      }
  }
  
  void DoorController(string trigger)
  {
      _animator.SetTrigger(trigger);
  }
  }
  

And my result is the same, the animation of the door repeats itself even when the player is in the trigger zone, I tumbled upon some other resources (here... here... here... here I tried to copy what this person did, but is the same... here... and here) about doors and triggers, and I still don't know how I am wrong or what am I doing wrong, I tried everything in those links

The door goes through all animations regardless the script, and the parameters, when I move my player inside the trigger zone loops between open and close animations no matter what

Could some one help me with this?

Thanks in advance

EDIT:

Here are some screenshots of my animator and updated code, for this update I followed this tutorial, just a little difference, I'm using a FPS Controller from the Unity standard assets

Updated code:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class DoorScript : MonoBehaviour 
{
    Animator _animator;
    bool doorOpen;

    // Use this for initialization
    void Start () 
    {
        doorOpen = false;
        _animator = GetComponent<Animator>();
    }

    /* // Update is called once per frame
    void Update () 
    {

    } */

    void OnTriggerEnter(Collider other)
    {
        if (other.gameObject.tag == "Player")
        {
            doorOpen = true;
            DoorController("isOpen");
        }
    }

    void OnTriggerExit(Collider other)
    {
         //These lines were modified
        if (doorOpen)
        {
            doorOpen = false;
            DoorController("isClosed");
        }
    }

    void DoorController(string trigger)
    {
        _animator.SetTrigger(trigger);
    }
}

Answer 1

Seems that other objects can trigger the door closing if they exit the trigger zone while the player is in it. Try using if (other.gameObject.tag == "Player") with the onTriggerExit(), too.

Answer 2

you have to make the trigger to fill the who room. onTriggerEnter() you have to play door-open animation and onTriggerExit() you have to play door-close animation. there are a lot of approaches to do this. I just told one of them.

sorry for careless answer. I edit. repeating animation is because loop time of animation is checked and you have to uncheck it. other reason can be that your trigger is colliding with other objects. you can simple ignore them by making different layers for them.

Answer 3

Solved! I'm so stupid! In the end, the trigger zone was very small and my player collided everytime and that's why the door opened and closed like crazy... I'm really thankful for all your answers and comments
