如何在 Unity3D 中查找列表中的 3 个元素是否相同
How to find if 3 elements in list are same in Unity3D
我正在统一开发纸牌游戏。我有 5 张不同的卡片(A、B、C、D、E),我手上最多可以有 6 张卡片。我有一个按钮。所以一旦我抽出一张卡片就点击按钮。所以所有这些功能都准备好了。但是我想在抽出的那些牌中执行一个动作。如果任意三张牌相似。
例如:- 我抽出 5 张牌 抽出的牌顺序是:A,A,A,B,C 现在如你所见,我有 3- A 我想执行 A 动作。或者如果卡片是这样的 A、B、C、C、C、E 如果想要执行 C 功能,因为有 3 个 C。因此,如果 3 张卡片类型相同,我想执行与其相关的操作。
所以为了更简要一点,我将解释一次流程。 Card-Draw 按钮单击 -> 每次点击继续获取卡片 -> 将卡片添加到名为 _CardList 的列表中并对列表中的卡片进行排序 -> 如果有 3 张相同的卡片,则执行一个操作。我在最后一次检查卡时遇到问题。
我已经做了一个方法,但是太庞大了,不可取。所以如果你们能在这方面帮助我,那将对我有很大帮助。谢谢,我会 post 我在下面对我尝试过的所有疑虑和问题。
Try#1
Have multiple list like:
List<Card> Alist;
List<Card> BList; //and so on until And keep creating list as long as card type
.
.
List<Card> Elist;
void DrawButton() // Function thats passed to the button. Meaning what to happen when the button is clicked
{
//Here we instantiate the card randomly from a list given from inspector.
GameObject card = Instantiate(cards._cardModel, _playerHandPoints[clicks].localPosition, _playerHandPoints[clicks].localRotation, mCardHolderParent.transform);
//We access the card script attached to card and give its type and everything
card.GetComponent<Cards>()._cardType = cards._cardType;
//Here we pass the instantiated card
AddNewCard(card.GetComponent<Cards>());
//Every time after adding we check if any list count is 3 and perform related action
CardMatchThreeChecker();
}
AddNewCard(Card inNewCard)
{
//in this function we check the card type and add it to their specific list & also add it to _cardList.
switch (inNewCard._cardType)
{
case CardType.A: AList.Add(inNewCard);
break;
case CardType.B: BList.Add(inNewCard);
break;
case CardType.C: CList.Add(inNewCard);
break;
case CardType.D: DList.Add(inNewCard);
break;
case CardType.E: EList.Add(inNewCard);
break;
default:
break;
}
_CardList.Add(inNewCard);
}
void CardMatchThreeChecker()
{
if (AList.Count == 3)
{
SceneManager.LoadScene(1);
}
if (BList.Count == 3)
{
SceneManager.LoadScene(2);
}
if (CList.Count == 3)
{
SceneManager.LoadScene(3);
}
if (DList.Count == 3)
{
SceneManager.LoadScene(4);
}
if (EList.Count == 3)
{
SceneManager.LoadScene(5);
}
}
问题 - 1:如果我以后添加任何新卡,我需要继续添加许多列表,这是不可取的,因为一次可玩的卡也可以达到或超过 20
问题-2:没有使用包含所有实例化卡片的列表“_cardList”。
问题 - 1 相反,我想检查 _CardList 列表本身是否有任何 3 项相似。就像每次我画一张卡片时,他们都会去并将自己添加到卡片列表的列表中,我想检查列表中是否有任何三个元素相似,然后执行相关操作。我在互联网上进行了搜索,但找不到或不知道该做什么或如何尝试。
但是我尝试了一种方法,但现在我陷入了下面提到的too.Method
These lines below come under a function called CardChecking() That is called in DrawButton(). Here Im saying it to check the list only if card count is more than 2 because we have a match only if 3 cards are there and we cant have a match if cards are less that 3 as we are checking if there are 3 similar cards. And as we want to check the elements of the list we have a for loop with (i,i+1,i+2) making it checking elements of the cardlist. Problem of this outside the snippet.
for (int i = 0; i < _CardList.Count; i++)
{
if (_CardList.Count > 2)
{
if(_CardList[i]._cardType == _CardList[i+1]._cardType && _CardList[i + 1]._cardType == _CardList[i+2]._cardType)
{
SceneManager.LoadScene(_CardList[i]._cardType.ToString());
}
else
{
continue;
}
}
}
我面临的问题是:例如,如果我抽了 3 张牌,我的卡片列表计数将是 3,这将满足我的条件并检查功能。如果我的卡片不是同一类型,那么它会转到下一步进行迭代,那时我的 i 值将是 cardList[1] ||卡片列表[2] && 卡片列表[2] || cardList[3] 表示我的 for 循环第二次迭代时我的卡片值为 1,2 和 3 但是当它检查 cardList[3] 时它抛出索引超出范围因为我的卡片列表计数是 3 并且它没有第 4 个元素for 循环正在检查。所以不知道如何克服这个问题。
我假设卡片的顺序无关紧要,并且认为您正在寻找 Linq GroupBy
// Just a simplified example since you didn't show your Card class
class Card
{
public CardType _cardType;
public Card(CardType type)
{
_cardType = type;
}
}
var list = new List<Card>
{
new Card(CardType.A),
new Card(CardType.B),
new Card(CardType.C),
new Card(CardType.C),
new Card(CardType.B),
new Card(CardType.B),
new Card(CardType.A),
new Card(CardType.A),
new Card(CardType.B)
};
// This creates separated groups according to the value of the card
var groups = list.GroupBy(c => c._cardType)
// Then it filters out only those groups that have 3 or more items
.Where(g => g.Count() >= 3);
// Then you can simply iterate through them
foreach (var @group in groups)
{
// The Key is the value the grouping was based on
// so in this example the Card._cardType
Debug.Log($"There are {@group.Count()} cads with cardType = {@group.Key}");
// you can also get all the according cards if needed
//var cards = @group.ToArray();
}
将打印
There are 3 cards with cardType = A
There are 4 cards with cardType = B
此外,如果您只想获得第一个具有 3
项的组,并且无论如何已经知道永远不会同时有两个或更多项,您可以去
// again first create separate groups based on the value
var group = list.GroupBy(c => c._cardType)
// Pick the first group that has at least 3 items
// or NULL if there is none
.FirstOrDefault(g => g.Count() >= 3);
if (group != null)
{
Debug.Log($"Found a group of {group.Count()} for the value = {group.Key}!");
}
else
{
Debu.Log("There is no group with 3 elements yet...");
}
要解决问题 - 1,您可以使用 Dictionary :
Dictionary<CardType,List<Card>> cardListDictionary = new Dictionary<CardType, List<Card>>();
AddNewCard(Card inNewCard)
{
if (!cardListDictionary.TryGetValue(inNewCard._cardType,out var list))
{
list = new List<Card>();
cardListDictionary.Add(inNewCard._cardType,list);
}
list.Add(inNewCard);
}
为了解决问题 - 2,像这样实现 CardChecking :
void CardChecking()
{
if (_CardList.Count > 2)
{
var type = _CardList[0]._cardType;
var count = 1;
for (int i = 1; i < _CardList.Count; i++)
{
if(_CardList[i]._cardType == type)
{
count++;
if (count == 3)
{
SceneManager.LoadScene(type.ToString());
}
}
else
{
type = _CardList[i]._cardType;
count = 1;
}
}
}
}
嗯,不确定我是否理解了整个画面。让我把问题简化一下,如果可行,那么就有解决方案了。
问题: 我有一个卡片列表,如果列表中有3个相同类型的卡片实例,我需要执行一个动作
答案:使用Linq按类型对列表进行分组。然后,过滤结果以找到“三张牌的情况”。
给你:
var answer = _CardList
.GroupBy(c => c.GetCardType())
.ToDictionary(g => g.Key, g => g.Count()) // Count by the card type.
.Where(x => x.Value >= 3) // Three or more cards of the same type.
.Select(x => x.Key) // Fetch the card type.
.FirstOrDefault(); // Only one match is needed.
if (answer != null) {
// answer is the type of the card that is counted 3 or more times.
}
如果您需要检测所有“三张牌情况”,请移除FirstOrDefault
并处理集合。
