I got a platform with 32 obstacles which are all included into an array (by tag). I transfer all of these values to a list using .ToList.
Everything works fine and all of the values are transferred to the list. Once the scene is played all of the 32 platforms are spawned which is also good.
What I want to do is to randomly remove values from the list and then transfer them back to the array (I know how to transfer them but not how to randomly remove the values). I tried with RemoveRange but this only removes values from a starting value to an end value even if randomized with Random.Range.
I want to randomly remove multiple items from the list not in order (for example remove the first item on the list then the 3rd then the 5th etc…).
I could do that by writing list.Remove(list[Random.Range(1,32)]); but I hope there are better methods…
Below is my code :
using System.Collections;
using System.Collections.Generic;
using System.Linq;
using UnityEngine;
public class RandomizeSpawn : MonoBehaviour {
public GameObject wallObs;
private GameObject[] allspawnPoint;
private GameObject[] spawnPoint;
private List<GameObject> disabledSpawns = new List<GameObject>();
private bool callOnce;
void Start () {
wallObs = GameObject.Find ("Wall");
callOnce = true;
}
void SpawnObstable () //Where the obstacles are spawned
{
foreach (GameObject respawnPoint in spawnPoint)
{
Instantiate(wallObs, new Vector3 (respawnPoint.transform.position.x,wallObs.transform.position.y,respawnPoint.transform.position.z), respawnPoint.transform.rotation);
callOnce = false;
}
}
void Update () {
allspawnPoint = GameObject.FindGameObjectsWithTag ("Spawner");
if (callOnce == true) {
disabledSpawns = allspawnPoint.ToList ();
Debug.Log (disabledSpawns.Count);
RandomizeSpawns ();
}
}
void RandomizeSpawns () //Where I remove only 1 item using random.range
{
disabledSpawns.Remove(disabledSpawns[Random.Range(1,32)]);
spawnPoint = disabledSpawns.ToArray (); //this is where I transfer the objects from the list to the array to get spawned
SpawnObstable ();
}
}
