Opening Door With Raycast

Questions & Answers
1

Ok so i have a script in which when the player is so far from the door and presses an Interact key the door they are standing front of opens. Every thing i have seems to be working just fine, except the door wont open without the player being right in front of the door, and i don’t know what to do.
If someone could help me figure this out that this would that would be awesome.

using UnityEngine;
using System.Collections;

public class Door : MonoBehaviour {

private float distance;
private GameObject player;
private Ray ray;

void Start () {
	player = GameObject.FindGameObjectWithTag ("Player");
}

void Update () {

	distance = Vector3.Distance(transform.position, player.transform.position);
	ray = Camera.main.ScreenPointToRay(Input.mousePosition);

	RaycastHit hit;

	if (Input.GetButtonDown("Interact") && distance < 20 && Physics.Raycast(ray, out hit) && hit.collider.gameObject.tag == "Door") {
		animation.Play("DoorOpening");
	}


}

}

A better/simpler way to detect door is to put a big sphere trigger on the door, and put something like this on the player:

void OnTriggerEnter (Collider col) {
    if (col.tag == "Door") {
        col.GetComponent<Animator>().SetBool("OpenDoor", true);
    }
}

Or similar.
Does that make sense?

perhaps try a larger value than 20 for your distance check.
You can also pass a distance value into your Physics.Raycast instead of performing the check yourself. This is a better solution as your currently checking the distance from the door pivot.

Also make sure nothing is blocking your raycast getting to the door such as another collider.
