Randomly spawning objects,Random Object and Spawn Point?

Questions & Answers
1

I want all 6 objects to spawn in. I want it to pick 1 of 8 spawns and assign all 6 objects to those 8 different spawns without spawning 2 in the same spot. heres my current code

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

public class RandomSpawn : MonoBehaviour
{
public Transform spawns;
public GameObject objects;

private int randomPref;
private int randomSpawn;

void Start()
{
    randomPref = Random.Range(0, 6);
    randomSpawn = Random.Range(0, 8);
    Instantiate(objects[randomPref], spawns[randomSpawn].transform.position, Quaternion.identity);
}

}

And it works. But not what i need it to do,I have 6 objects, I need them to to pick 1 of 8 spawn points.

So here’s the code:

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

public class RandomSpawn : MonoBehaviour
{
public Transform spawns;
public GameObject objects;

private int randomPref;
private int randomSpawn;

void Start()
{
    randomPref = Random.Range(0, 6);
    randomSpawn = Random.Range(0, 8);
    Instantiate(objects[randomPref], spawns[randomSpawn].transform.position, Quaternion.identity);
}

}

And it works, It picks 1 of 6 objects and spawns it in 1 of 8 spawns, but i want it to pick all 6 and assign all 6 to 1 on of 8 random spawn points without spawning 2 objects in the same spot.

using UnityEngine;
using System.Collections.Generic;

public class RandomSpawn : MonoBehaviour
{ 
    public Transform[] spawns;
    public GameObject[] objects;

    void Start()
    {
        SpawnObjects( objects, spawns );
    }

    private void SpawnObjects( GameObject[] gameObjects, Transform[] locations, bool allowOverlap = true )
    {
        List<GameObject> remainingGameObjects = new List<GameObject>( gameObjects );
        List<GameObject> freeLocations        = new List<GameObject>( locations );

        if( locations.Length < gameObjects.Length )
            Debug.LogWarning( allowOverlap  ? "There are more gameObjects than locations. Some objects will overlap." : "There are not enough locations for all the gameObjects. Some won't spawn.");

        while( remainingGameObjects.Count > 0 )
        {
            if( freeLocations.Count == 0 )
            {
                if( allowOverlap ) freeLocations.AddRange( locations );
                else               break ;
            }

            int gameObjectIndex = Random.Range( 0, remainingGameObjects.Count );
            int locationIndex   = Random.Range( 0, freeLocations.Count );
            Instantiate(gameObjects[gameObjectIndex], locations[locationIndex].position, Quaternion.identity);
            remainingGameObjects.RemoveAt( gameObjectIndex );
            freeLocations.RemoveAt( locationIndex );
        }
    }
}

Here is the updated code without errors.

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

public class random : MonoBehaviour
{
public Transform[] spawns;
public GameObject[] objects;

    void Update()
    {
        
        spawn(objects, spawns);
    }
    
    void spawn(GameObject[] gameObjects, Transform[] locations, bool allowOverlap = true){
    
       List<GameObject> remainingGameObjects = new List<GameObject>( gameObjects );
         List<Transform> freeLocations        = new List<Transform>( locations );
 
         if( locations.Length < gameObjects.Length )
             Debug.LogWarning( allowOverlap  ? "There are more gameObjects than locations. Some objects will overlap." : "There are not enough locations for all the gameObjects. Some won't spawn.");
             
                   while( remainingGameObjects.Count > 0 )
         {
             if( freeLocations.Count == 0 )
             {
                 if( allowOverlap ) freeLocations.AddRange( locations );
                 else               break ;
             }
 
             int gameObjectIndex = Random.Range( 0, remainingGameObjects.Count );
             int locationIndex   = Random.Range( 0, freeLocations.Count );
             Instantiate(gameObjects[gameObjectIndex], locations[locationIndex].position, Quaternion.identity);
             remainingGameObjects.RemoveAt( gameObjectIndex );
             freeLocations.RemoveAt( locationIndex );
         }
}
