Unity 制作一个分数统计系统
短信预约 -IT技能 免费直播动态提醒
项目中经常遇到分数统计的需求，例如我们执行了某项操作或做了某个题目，操作正确则计分，相反则不计分失去该项分数，为了应对需求需要一个分数统计系统。
首先定义一个分数信息的数据结构，使用Serializable特性使其可序列化：
using System;
using UnityEngine;
namespace SK.Framework
{
/// <summary>
/// 分数信息
/// </summary>
[Serializable]
public class ScoreInfo
{
/// <summary>
/// ID
/// </summary>
public int id;
/// <summary>
/// 描述
/// </summary>
[TextArea]
public string description;
/// <summary>
/// 分值
/// </summary>
public float value;
}
}ScoreInfo类可序列化后，创建ScoreProfile类继承ScriptableObject使其作为可通过菜单创建的Asset资产：
using UnityEngine;
namespace SK.Framework
{
/// <summary>
/// 分数配置文件
/// </summary>
[CreateAssetMenu]
public class ScoreProfile : ScriptableObject
{
public ScoreInfo[] scores = new ScoreInfo[0];
}
}
使用ScoreIDConstant类编写所有分数项ID常量，创建ScoreID特性并使用PropertyDrawer使其可在面板选择：
namespace SK.Framework
{
public sealed class ScoreIDConstant
{
public const int INVALID = -1;
}
}
using UnityEngine;
#if UNITY_EDITOR
using UnityEditor;
using System;
using System.Reflection;
using System.Collections;
#endif
namespace SK.Framework
{
public class ScoreIDAttribute : PropertyAttribute { }
#if UNITY_EDITOR
[CustomPropertyDrawer(typeof(ScoreIDAttribute))]
public class ScoreIDPropertyAttributeDrawer : PropertyDrawer
{
private int[] scoreIDArray;
private GUIContent[] scoreIDConstArray;
public override float GetPropertyHeight(SerializedProperty property, GUIContent label)
{
return base.GetPropertyHeight(property, label);
}
public override void OnGUI(Rect position, SerializedProperty property, GUIContent label)
{
if (scoreIDConstArray == null)
{
ArrayList constants = new ArrayList();
FieldInfo[] fieldInfos = typeof(ScoreIDConstant).GetFields(BindingFlags.Public | BindingFlags.Static | BindingFlags.FlattenHierarchy);
for (int i = 0; i < fieldInfos.Length; i++)
{
var fi = fieldInfos[i];
if (fi.IsLiteral && !fi.IsInitOnly) constants.Add(fi);
}
FieldInfo[] fieldInfoArray = (FieldInfo[])constants.ToArray(typeof(FieldInfo));
scoreIDArray = new int[fieldInfoArray.Length];
scoreIDConstArray = new GUIContent[fieldInfoArray.Length];
for (int i = 0; i < fieldInfoArray.Length; i++)
{
scoreIDConstArray[i] = new GUIContent(fieldInfoArray[i].Name);
scoreIDArray[i] = (int)fieldInfoArray[i].GetValue(null);
}
}
var index = Array.IndexOf(scoreIDArray, property.intValue);
index = Mathf.Clamp(index, 0, scoreIDArray.Length);
index = EditorGUI.Popup(position, label, index, scoreIDConstArray);
property.intValue = scoreIDArray[index];
}
}
#endif
}有了ScoreID特性后，用于ScoreInfo中的id字段：
using System;
using UnityEngine;
namespace SK.Framework
{
/// <summary>
/// 分数信息
/// </summary>
[Serializable]
public class ScoreInfo
{
/// <summary>
/// ID
/// </summary>
[ScoreID]
public int id;
/// <summary>
/// 描述
/// </summary>
[TextArea]
public string description;
/// <summary>
/// 分值
/// </summary>
public float value;
}
}
数据可配置后，创建分数项Score类，声明以下字段：Flag表示该分数项的标识，注册分数项时返回该标识，用于后续获取或取消该分数项分值；Description即分数项的描述；Value表示该分数项的分值；IsObtained用于标记该分数项的分值是否已经获得。
namespace SK.Framework
{
/// <summary>
/// 分数项
/// </summary>
public class Score
{
/// <summary>
/// 标识
/// </summary>
public string Flag { get; private set; }
/// <summary>
/// 描述
/// </summary>
public string Description { get; private set; }
/// <summary>
/// 分值
/// </summary>
public float Value { get; private set; }
/// <summary>
/// 是否已经获得分值
/// </summary>
public bool IsObtained { get; set; }
public Score(string flag, string description, float value)
{
Flag = flag;
Description = description;
Value = value;
}
}
}为了实现一个分数组合，例如某项操作，通过A操作方式可获得5分，通过B操作方式可获得3分，它们之间是互斥的，即获得了前者的5分，就不会获得后者的3分，创建ScoreGroup类：
using System.Collections.Generic;
namespace SK.Framework
{
/// <summary>
/// 分数组合
/// </summary>
public class ScoreGroup
{
/// <summary>
/// 组合描述
/// </summary>
public string Description { get; private set; }
/// <summary>
/// 计分模式
/// Additive表示组合内分值进行累加
/// MutuallyExclusive表示组内各分数项互斥 获得其中一项分值 则取消其它项分值
/// </summary>
public ValueMode ValueMode { get; private set; }
public List<Score> Scores { get; private set; }
public ScoreGroup(string description, ValueMode valueMode, params Score[] scores)
{
Description = description;
ValueMode = valueMode;
Scores = new List<Score>(scores);
}
public bool Obtain(string flag)
{
var target = Scores.Find(m => m.Flag == flag);
if (target != null)
{
switch (ValueMode)
{
case ValueMode.Additive: target.IsObtained = true; break;
case ValueMode.MutuallyExclusive:
for (int i = 0; i < Scores.Count; i++)
{
Scores[i].IsObtained = Scores[i] == target;
}
break;
default: break;
}
if (ScoreMaster.DebugMode)
{
ScoreMaster.LogInfo($"获取分数组合 [{Description}] 中标识为 [{flag}] 的分值 [{target.Description}]");
}
return true;
}
if (ScoreMaster.DebugMode)
{
ScoreMaster.LogError($"分数组合 [{Description}] 中不存在标识为 [{flag}] 的分数项.");
}
return false;
}
public bool Cancle(string flag)
{
var target = Scores.Find(m => m.Flag == flag);
if (target != null)
{
if (ScoreMaster.DebugMode)
{
ScoreMaster.LogInfo($"取消分数组合 [{Description}] 中标识为 [{flag}] 的分数项分值 [{target.Description}]");
}
target.IsObtained = false;
return true;
}
if (ScoreMaster.DebugMode)
{
ScoreMaster.LogError($"分数组合 [{Description}] 中不存在标识为 [{flag}] 的分数项.");
}
return false;
}
}
}
namespace SK.Framework
{
/// <summary>
/// 计分方式
/// </summary>
public enum ValueMode
{
/// <summary>
/// 累加的
/// </summary>
Additive,
/// <summary>
/// 互斥的
/// </summary>
MutuallyExclusive,
}
}最终编写分数管理类，封装Create、Obtain、Cancle、GetSum函数，分别用于创建分数组合、获取分数、取消分数、获取总分，实现Editor类使分数信息在Inspector面板可视化：
using System;
using UnityEngine;
using System.Collections.Generic;

using System.Reflection;
#endif

{
if (instance == null)
{

}
if (instance == null)
{

instance.profile = Resources.Load<ScoreProfile>("Score Profile");
if (instance.profile == null && DebugMode)
{
LogError("加载分数信息配置表失败.");
}
}
return instance;
}
}
#endregion

{
var info = Array.Find(profile.scores, m => m.id == idArray[i]);
if (info != null)
{
var flag = Guid.NewGuid().ToString();
flags[i] = flag;
scores[i] = new Score(flag, info.description, info.value);
if (DebugMode) LogInfo($"创建分数ID为 [{idArray[i]}] 的分数项 [{info.description}] flag: {flag}");
}
else if (DebugMode)
{
LogError($"配置中不存在ID为 [{idArray[i]}] 的分数信息.");
}
}
ScoreGroup group = new ScoreGroup(description, valueMode, scores);
groups.Add(description, group);
if (DebugMode)
{
LogInfo($"创建分数组合 [{description}] 计分模式[{valueMode}]");
}
return flags;
}
private bool ObtainValue(string groupDescription, string flag)
{
if (groups.TryGetValue(groupDescription, out ScoreGroup target))
{
return target.Obtain(flag);
}
if (DebugMode)
{
LogError($"不存在分数组合 [{groupDescription}].");
}
return false;
}
private bool CancleValue(string groupDescription, string flag)
{

}
private float GetSumValue()

foreach (var kv in groups)
