Unity資料的持久化儲存 ☞ Xml方式儲存

要儲存的資料

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

[System.Serializable]//可序列化特性
public class Save
{
	public List<int> livingTagetPositions = new List<int>();
	public List<int> livingMonsterTypes = new List<int>();

	public int shootNum = 0;
	public int score = 0;
}
           

資料的儲存與讀取
