遍历列表以检查boolean在ScriptableObject中是否为真 [英] Loop through a List to check whether a bool is true within a ScriptableObject
问题描述
我有一个字符可写对象'Character'，并且有一个布尔IsMale.我也有一个团队"可编写脚本的对象，它具有来自角色可编写脚本的对象"类的字符列表.现在，我想在Team Class中创建一个自定义方法，以循环浏览此列表，并检查有多少个男性角色，而没有几个.
I have a character Scriptable Object 'Character' and it has a bool IsMale. I also have a 'Team' Scriptable Object and it has a list of Characters from the Character Scriptable Object Class. Now, I want to create a custom method in the Team Class for looping through this list and check how many characters are male and how many are not.
Character.cs
Character.cs
using UnityEngine;
// Personal Attributes
public string firstName;
public string middleName;
public string lastName;
public string fullName;
public bool isMale;
Team.cs
using UnityEngine;
public List<Character> characters;
// For adding ten players.
public void AddPlayer(Character p1, p2, p3, p4, p5, p6, p7, p8, p9, p10)
{
characters.Add(p1);
characters.Add(p2);
characters.Add(p3);
characters.Add(p4);
characters.Add(p5);
characters.Add(p6);
characters.Add(p7);
characters.Add(p8);
characters.Add(p9);
characters.Add(p10);
}
// I want to loop through these ten characters in the list and tell how many are males and how many are not
同样，我想在Team Class中创建一个自定义方法来循环浏览此列表，并检查有多少个男性角色，有几个不是男性角色.
Again, I want to create a custom method in the Team Class for looping through this list and check how many characters are male and how many are not.

推荐答案
您可以例如为此使用 Linq计数(我宁愿使用属性在这里，但是您可以使用课程方法进行同样的操作.):
You can e.g. use Linq Count for that (I'ld rather use properties here but you could do the same using methods ofcourse.):
using System.Linq;
public int Males
{
get
{
return characters != null ? characters.Count(c => c.isMale) : 0;
}
}
public int Females
{
get
{
return characters != null ? characters.Count(c => !c.isMale) : 0;
}
}
您可以简单地使用该值，例如
You would simply use that value like e.g.
Debug.LogFormat(this, "Males: {0}, Females: {1}", Males, Females);
提示:即使Unity Inspector自动初始化List和数组字段，您也应该始终将其与定义一起使用，例如
Hint: even though the Unity Inspector automatically initializes List and array fields you shoudl always do it together with the definition like
public List<Character> characters = new List<Character>(10);
只是为了确保在调用Add时永远不会null，并确保将默认容量设置为您希望列表以后拥有的计数.
just to be sure it is never null when calling Add and make sure to set a default capacity to what you expect the List to have as Count later.
或者，您也可以使用
Character[] characters = new Character[10];
因为您始终不希望尺寸是动态的. (注意，但是Unity中的Inspector始终会覆盖这些定义)
since you don't want the size to be dynamic anyway. (Note however that the Inspector in Unity always overrides those definitions)
更好的原因:List在后台始终将其值存储在数组中.通过使用Add添加元素，它每次都会检查数组是否仍然足够大，如果不足够，则将其扩展为两倍大小(请参见这里)
The reason why this is better: List in the background stores it's values in an array anyway. By adding elements using Add it everytime checks if the array is still big enough and if not expands it to the double size (see here)
public void AddPlayer(Character p1, p2, p3, p4, p5, p6, p7, p8, p9, p10)
{
characters.Add(p1); // characters has now capacity 4
characters.Add(p2);
characters.Add(p3);
characters.Add(p4);
characters.Add(p5); // characters reallocated and has now capacity 8
characters.Add(p6);
characters.Add(p7);
characters.Add(p8);
characters.Add(p9); // characters reallocated and has now capacity 16
characters.Add(p10);
}
所以您看到使用Add 10或11次总是分配比实际需要更多的内存.
so you see using Add 10 or 11 times always allocates more memory than actually needed.
我会
// hide because if you do it via the method you probably don't
// want to add items via Inspector which would get overwritten later anyway
[HideInInspector] public Character[] characters = new Character[10];
public void AddPlayer(Character p1, p2, p3, p4, p5, p6, p7, p8, p9, p10)
{
characters[0] = p1;
characters[1] = p2;
characters[2] = p3;
characters[3] = p4;
characters[4] = p5;
characters[5] = p6;
characters[6] = p7;
characters[7] = p8;
characters[8] = p9;
characters[9] = p10;
}
除此之外，在数组或列表中访问或更改值的方式没有太大区别.
other than that there is no big difference between how you access or change values in array or List.
要设置每个字符所需的所有值，您可以/应该使用适当的构造函数(不过我会更改命名):
For setting all the values you need for every character you could/should use a proper constructor (I would change the naming though):
[Serializable]
public class Character
{
// Personal Attributes
public string firstName;
public string middleName;
public string lastName;
public string fullName;
public bool isMale;
public Character(string _firstName, string _middleName, string _lastName, bool _isMale)
{
firstName = _firstName;
middleName = _middleName;
lastName = _lastName;
fullName = string.Format("{0} {1} {2}", firstName, middleName, lastName);
isMale = _isMale;
}
}
