[Unity]在场景中随机生成不同位置且不重叠的物体
1.前言
最近任务需要用到Unity在场景中随机生成物体，且这些物体不能重叠，简单记录一下。
参考资料:How to ensure that spawned targets do not overlap ?
2.结果与代码
结果如下所示：
代码如下所示：
using System.Collections.Generic;
using UnityEngine;namespace Assets.Scripts
{public class NewMonoBehaviour : MonoBehaviour{public GameObject objectForSpawn;private List<SpawnObject> spawnObjectList;private int objectCount = 50;private void Start(){CreateCollections();Generate(objectCount);}void CreateCollections(){spawnObjectList = new List<SpawnObject>();}void Generate(int objectCount){CreateObjects();void CreateObjects(){for (int i = 0; i < objectCount; i++){Vector3 objectPosition = GetPosition();SpawnObject sO = new SpawnObject(objectPosition);spawnObjectList.Add(sO);}} SpawnGameObjects();void SpawnGameObjects(){List<SpawnObject> spawnedObjects = new List<SpawnObject>();List<SpawnObject> notSpawnedObjects = new List<SpawnObject>();foreach (SpawnObject item in spawnObjectList){Vector3 spawnPosition = GetPosition();if (item.objectPosition != spawnPosition){Instantiate(objectForSpawn, spawnPosition, transform.rotation);spawnedObjects.Add(item);}else{notSpawnedObjects.Add(item);}}Debug.Log("Object spawned :" + spawnedObjects.Count);Debug.Log("Object notSpawned :" + notSpawnedObjects.Count);}}Vector3 GetPosition(){Vector3 randmPosition;randmPosition.x = Random.Range(1, 100);randmPosition.y = Random.Range(1, 100);randmPosition.z = Random.Range(1, 100);return randmPosition;}}public class SpawnObject{public Vector3 objectPosition;public SpawnObject(Vector3 objectPosition){this.objectPosition = objectPosition;}}
//In case you want serialize this position for example for save you better use float[3] for position then vector.
