Sorting a list by distance to an object?
Hi. I think similar questions have been answered already, but I have had a hard time understanding those answers.
Basically, I want to sort a list of transforms by distance to the player, so the closest transform is at the top and of the list and farthest is at the bottom. I don't use lists that often so I'm not too familiar with their sort functions or how they work. A sample script or explanation would be greatly appreciated.
Thanks.
This ended up working for me, never used linq or OrderBy before so I'm still not too sure why this works but it does. If someone has a better method or can explain this method, I'd be happy to hear it.
using UnityEngine;
using System.Collections;
using System.Linq;
public class SortDistance : MonoBehaviour {
public GameObject[] points;
public GameObject sphere;
void Start()
{
points = points.OrderBy(point => Vector3.Distance(sphere.transform.position, point.transform.position)).ToArray();
foreach (GameObject point in points)
Debug.Log(point.name);
}
}
using UnityEngine;
using System.Collections;
using System.Collections.Generic;
public class SortDistance : MonoBehaviour
{
public GameObject sphere;
public List<Transform> spawnPoints;
void Start()
{
Sort();
}
void Sort()
{
spawnPoints.Sort(delegate (Transform a, Transform b)
{
return Vector3.Distance(sphere.transform.position, a.transform.position).CompareTo(Vector3.Distance(sphere.transform.position, b.transform.position));
});
foreach (Transform point in spawnPoints)
Debug.Log(point.name);
}
}
This method also seems to work. Taken from http://answers.unity3d.com/questions/246781/sort-transforms-by-distance-to-player.html If anyone has the same problem.
