编辑：已经得到了答案。我将玩家的清单Inv更改为整数列表，并在游戏初始加载时将物品导入字典中，如下所示：
public static class InitLoad
{
static List<ItemEquipmentWeapon> weapons;
public static Dictionary<int, Item> ItemIDList = new Dictionary<int, Item>();
public static void PreLoading()
{
string path, filePath,
weaponFile = @"\WeaponsItem.aid";
XmlSerializer SerializerObj;
FileStream ReadFileStream;
path = string.Format(@"{0}\AwesomeRPG\Data\Items",
Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData));
filePath = string.Format(@"{0}\{1}", path, weaponFile);
SerializerObj = new XmlSerializer(typeof(ItemEquipmentWeapon));
ReadFileStream = new FileStream(filePath, FileMode.Open, FileAccess.Read, FileShare.Read);
weapons = (List<ItemEquipmentWeapon>)SerializerObj.Deserialize(ReadFileStream);
foreach (Item item in weapons)
{
ItemIDList.Add(item.ID, item);
}
}
}
意思是我可以使用我的player类来完成这个任务：
[Serializable()]
public class Player : Entity
{
public string Name { get; set; }
public int MaxHP { get; set; }
public int Level { get; set; }
public int XP { get; set; }
public int Str { get; set; }
public int End { get; set; }
public int Dex { get; set; }
public int Agi { get; set; }
public int Wis { get; set; }
public int Int { get; set; }
//Create a list of Item Id's for inventory
public List<int> Inv { get; set; }
private int lHand;
private int rHand;
public int LHand
{
get
{ return lHand; }
set
{
if (!value.THand)
{
lHand = value;
}
else lHand = null;
}
}
public int RHand
{
get
{ return rHand; }
set
{ rHand = value; }
}
internal Player() { }
public Player(string name, int maxhp, int hp, int lvl, int exp, int str, int end, int dex, int agi, int wis, int inte)
: base(true, hp)
{
Name = name;
MaxHP = maxhp;
Level = lvl;
XP = exp;
Str = str;
End = end;
Dex = dex;
Agi = agi;
Wis = wis;
Int = inte;
Inv = new List<int>();
}
public List<string> GetInv()
{
List<string> val = new List<string>();
Item item;
foreach (int i in Inv)
{
InitLoad.ItemIDList.TryGetValue(i, out item);
val.Add(item.Name);
}
return val;
}
public void AddItem(Item i, int amt)
{
for (int j = 0; j < amt; j++)
{
Inv.Add(i.ID);
}
}
public void AddItem(Item i){
AddItem(i, 1); }
public void RemoveItem(Item i, int amt)
{
int count = 0;
foreach (int item in Inv)
{
if (item == i.ID)
{
Inv.Remove(item);
count++;
}
if (count == amt)
{
break;
}
}
}
public void RemoveItem(Item i){
RemoveItem(i, 1); }
public bool HasItem(Item i, int amt)
{
int count = 0;
foreach (int item in Inv)
{
if (item == i.ID)
{
count++;
}
}
return count >= amt;
}
public bool HasItem(Item i){
return HasItem(i, 1); }
}
希望这可以帮助其他人！
原始问题：
所以，我正在制作一个愚蠢的小RPG游戏，使用窗体来测试我的技能，并且我正在解决保存问题。目前它保存到一个XML文件中，自定义扩展名为（.asd）。这是我的保存/加载代码：
public static class SaveGame
{
public static void Save(Player player)
{
string myfile = string.Format(@"{1}\AwesomeRPG\Saves\{0}Save.asd", player.Name, Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData));
//Delete file if it already exists
if (File.Exists(myfile)) System.IO.File.Delete(myfile);
//Create/Write to the file
FileStream outFile = File.Create(myfile);
XmlSerializer Serializer = new XmlSerializer(typeof(Player));
Serializer.Serialize(outFile, player);
outFile.Close();
}
public static Player Load(string FileName)
{
string myfile = string.Format(@"{1}\AwesomeRPG\Saves\{0}Save.asd", FileName, Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData));
if (!File.Exists(myfile)) return null;
XmlSerializer Serializer = new XmlSerializer(typeof(Player));
FileStream ReadFileStream = new FileStream(myfile, FileMode.Open, FileAccess.Read, FileShare.Read);
return (Player)Serializer.Deserialize(ReadFileStream);
}
}
正如您所想象的那样，这将保存Inv列表中任何项目的所有详细信息。 但是，我希望所有存在的项目在游戏启动时都能被加载（创建它们的实例），并且我需要一种方法让保存文件保留对这些实例的引用，而不是创建新实例。
游戏启动时加载的实例也包含在XML文件中，然后根据项目类型加载到单独的列表中，例如所有ItemEquipmentWeapon实例（继承ItemEquipment，后者继承Item）都在WeaponItem.aid文件中，该文件以XML格式存储，并加载到List中。
是否有任何方法可以通过引用将Inv内容保存并从玩家保存文件中加载，以便可以使用在初始加载期间设置的现有实例？
编辑： 突然想到，让一些人看看Player类的编码可能有所帮助，所以在此提供：
[Serializable()]
public class Player : Entity
{
public string Name { get; set; }
public int MaxHP { get; set; }
public int Level { get; set; }
public int XP { get; set; }
public int Str { get; set; }
public int End { get; set; }
public int Dex { get; set; }
public int Agi { get; set; }
public int Wis { get; set; }
public int Int { get; set; }
public List<Item> Inv { get; set; }
private ItemEquipmentWeapon lHand;
private ItemEquipmentWeapon rHand;
public ItemEquipmentWeapon LHand
{
get
{ return lHand; }
set
{
if (!value.THand)
{
lHand = value;
}
else lHand = null;
}
}
public ItemEquipmentWeapon RHand
{
get
{ return rHand; }
set
{ rHand = value; }
}
internal Player() { }
public Player(string name, int maxhp, int hp, int lvl, int exp, int str, int end, int dex, int agi, int wis, int inte)
: base(true, hp)
{
Name = name;
MaxHP = maxhp;
Level = lvl;
XP = exp;
Str = str;
End = end;
Dex = dex;
Agi = agi;
Wis = wis;
Int = inte;
Inv = new List<Item>();
}
public List<string> GetInv()
{
List<string> val = new List<string>();
foreach (Item item in Inv)
{
val.Add(item.Name);
}
return val;
}
public void AddItem(Item i, int amt)
{
for (int j = 0; j < amt; j++)
{
Inv.Add(i);
}
}
public void AddItem(Item i){
AddItem(i, 1); }
public void RemoveItem(Item i, int amt)
{
int count = 0;
foreach (Item item in Inv)
{
if (item == i)
{
Inv.Remove(item);
count++;
}
if (count == amt)
{
break;
}
}
}
public void RemoveItem(Item i){
RemoveItem(i, 1); }
public bool HasItem(Item i, int amt)
{
int count = 0;
foreach (Item item in Inv)
{
if (item == i)
{
count++;
}
}
return count >= amt;
}
public bool HasItem(Item i){
return HasItem(i, 1); }
}
显然，从XML加载物品实例的代码在游戏加载时也非常有用，但我尚未编写该代码，我不确定如何去做。
到目前为止，我有这个：
public static class InitLoad
{
static List<ItemEquipmentWeapon> weapons;
public static void PreLoading()
{
string path, filePath,
weaponFile = @"\WeaponsItem.aid";
XmlSerializer SerializerObj;
FileStream ReadFileStream;
path = string.Format(@"{0}\AwesomeRPG\Data\Items",
Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData));
filePath = string.Format(@"{0}\{1}", path, weaponFile);
SerializerObj = new XmlSerializer(typeof(ItemEquipmentWeapon));
ReadFileStream = new FileStream(filePath, FileMode.Open, FileAccess.Read, FileShare.Read);
weapons = (List<ItemEquipmentWeapon>)SerializerObj.Deserialize(ReadFileStream);
}
}
非常感谢您的帮助！
