同学你好，可能是存在死循环，会造成Unity卡死，检查一下我们的代码。

using System.Collections; using System.Collections.Generic; using UnityEngine; public class MapCreation : MonoBehaviour { public GameObject[] item; private List itemPositionList = new List(); private void Awake() { CreateItem(item[0], new Vector3(0, -8, 0), Quaternion.identity); CreateItem(item[1], new Vector3(-1, -8, 0), Quaternion.identity); CreateItem(item[1], new Vector3(1, -8, 0), Quaternion.identity); for (int i = -1; i < 2; i++) { CreateItem(item[1], new Vector3(i, -7, 0), Quaternion.identity); } for (int i = -11; i < 12; i++) { CreateItem(item[6], new Vector3(i, 9, 0), Quaternion.identity); } for(int i = -11; i< 12; i++) { CreateItem(item[6], new Vector3(i, -9, 0), Quaternion.identity); } for(int i = -8; i < 9; i++) { CreateItem(item[6], new Vector3(-11, i, 0), Quaternion.identity); } for(int i = -8; i < 9; i++) { CreateItem(item[6], new Vector3(11, i, 0), Quaternion.identity); } for(int i = 0; i < 60; i++) { CreateItem(item[1], CreateRandomPosition(), Quaternion.identity); } for(int i = 0; i < 20; i++) { CreateItem(item[2], CreateRandomPosition(), Quaternion.identity); } for(int i = 0; i < 20; i++) { CreateItem(item[4], CreateRandomPosition(), Quaternion.identity); } for (int i = 0; i < 20; i++) { CreateItem(item[5], CreateRandomPosition(), Quaternion.identity); } } private void CreateItem(GameObject createGameObject, Vector3 createPosition, Quaternion createRotation) { GameObject itemGo = Instantiate(createGameObject, createPosition, createRotation); itemGo.transform.SetParent(gameObject.transform); itemPositionList.Add(createPosition); } private Vector3 CreateRandomPosition() { while (true) { Vector3 createPosition = new Vector3(Random.Range(-9, -10), Random.Range(-7, 8), 0); if (!HasThePosition(createPosition)) { return createPosition; } } } private bool HasThePosition(Vector3 createPos) { for (int i = 0; i < itemPositionList.Count; i++) { if (createPos == itemPositionList[i]) { return true; } } return false; } }

using System.Collections; using System.Collections.Generic; using UnityEngine; public class MapCreation : MonoBehaviour { public GameObject[] item; private List itemPositionList = new List(); private void Awake() { CreateItem(item[0], new Vector3(0, -8, 0), Quaternion.identity); CreateItem(item[1], new Vector3(-1, -8, 0), Quaternion.identity); CreateItem(item[1], new Vector3(1, -8, 0), Quaternion.identity); for (int i = -1; i < 2; i++) { CreateItem(item[1], new Vector3(i, -7, 0), Quaternion.identity); } for (int i = -11; i < 12; i++) { CreateItem(item[6], new Vector3(i, 9, 0), Quaternion.identity); } for(int i = -11; i< 12; i++) { CreateItem(item[6], new Vector3(i, -9, 0), Quaternion.identity); } for(int i = -8; i < 9; i++) { CreateItem(item[6], new Vector3(-11, i, 0), Quaternion.identity); } for(int i = -8; i < 9; i++) { CreateItem(item[6], new Vector3(11, i, 0), Quaternion.identity); } for(int i = 0; i < 60; i++) { CreateItem(item[1], CreateRandomPosition(), Quaternion.identity); } for(int i = 0; i < 20; i++) { CreateItem(item[2], CreateRandomPosition(), Quaternion.identity); } for(int i = 0; i < 20; i++) { CreateItem(item[4], CreateRandomPosition(), Quaternion.identity); } for (int i = 0; i < 20; i++) { CreateItem(item[5], CreateRandomPosition(), Quaternion.identity); } } private void CreateItem(GameObject createGameObject, Vector3 createPosition, Quaternion createRotation) { GameObject itemGo = Instantiate(createGameObject, createPosition, createRotation); itemGo.transform.SetParent(gameObject.transform); itemPositionList.Add(createPosition); } private Vector3 CreateRandomPosition() { while (true) { Vector3 createPosition = new Vector3(Random.Range(-9, -10), Random.Range(-7, 8), 0); if (!HasThePosition(createPosition)) { return createPosition; } } } private bool HasThePosition(Vector3 createPos) { for (int i = 0; i < itemPositionList.Count; i++) { if (createPos == itemPositionList[i]) { return true; } } return false; } }

是下边我们自己添加的代码问题，添加的60,20，20个游戏物体可能把位置用完了所以它卡死了。可以把这些删除，如果想加可以少加一点，也可以把我们代码优化一下，如果目前不会做可以先搁置往后学习其他案例。
