一、需求分析与技术选型

1.1 需求背景

在Unity项目开发中，AssetBundle依赖关系管理是性能优化的关键。当项目资源量达到GB级别时，依赖树深度可能超过10层，容易导致：

资源重复打包（平均冗余率可达15%-30%）
加载顺序错误引发内存泄漏
热更新包体大小失控

1.2 技术选型

‌Unity Editor扩展‌：基于EditorWindow实现可视化界面
‌图形绘制方案‌：采用UGUI + 自定义Shader实现高效渲染
‌数据解析核心‌：
- AssetBundleManifest解析
- 依赖树形结构构建算法
‌交互设计‌：支持多指触控的层级展开/折叠操作

二、核心模块实现

2.1 数据解析模块

public class ABDependencyAnalyzer { // 获取主清单文件 AssetBundleManifest GetMainManifest() { string path = Path.Combine(Application.streamingAssetsPath, "AssetBundles"); AssetBundle ab = AssetBundle.LoadFromFile(path); return ab.LoadAsset<AssetBundleManifest>("AssetBundleManifest"); } // 构建依赖树 Dictionary<string, ABNode> BuildDependencyTree() { var manifest = GetMainManifest(); Dictionary<string, ABNode> nodeMap = new Dictionary<string, ABNode>(); foreach (string abName in manifest.GetAllAssetBundles()) { if (!nodeMap.ContainsKey(abName)) { nodeMap[abName] = new ABNode(abName); } string[] dependencies = manifest.GetAllDependencies(abName); foreach (string dep in dependencies) { if (!nodeMap.ContainsKey(dep)) { nodeMap[dep] = new ABNode(dep); } nodeMap[abName].AddDependency(nodeMap[dep]); } } return nodeMap; } } public class ABNode { public string Name; public List<ABNode> Dependencies = new List<ABNode>(); public List<ABNode> Dependents = new List<ABNode>(); // 反向引用 }

2.2 可视化渲染模块

采用基于ComputeShader的实例化渲染方案，支持10万级节点流畅显示：

// 节点着色器核心逻辑 void vert (in appdata_full v, out Input o) { UNITY_INITIALIZE_OUTPUT(Input, o); // 动态计算节点位置 float2 pos = _Positions[v.instanceID].xy; float scale = _Positions[v.instanceID].z; v.vertex.xyz *= scale; v.vertex.xy += pos; o.color = _Colors[v.instanceID]; } // 布局算法（层次布局改进版） void CalculateLayout() { Dictionary<ABNode, int> depths = new Dictionary<ABNode, int>(); // 广度优先遍历计算层级 Queue<ABNode> queue = new Queue<ABNode>(); foreach (var node in rootNodes) { queue.Enqueue(node); depths[node] = 0; } while (queue.Count > 0) { ABNode current = queue.Dequeue(); foreach (var child in current.Dependencies) { if (!depths.ContainsKey(child) || depths[child] < depths[current] + 1) { depths[child] = depths[current] + 1; queue.Enqueue(child); } } } // 基于层级进行布局 Dictionary<int, float> layerPos = new Dictionary<int, float>(); foreach (var node in allNodes) { int depth = depths[node]; float x = layerPos.ContainsKey(depth) ? layerPos[depth] : 0; node.Position = new Vector2(x, -depth * VERTICAL_SPACING); layerPos[depth] = x + HORIZONTAL_SPACING; } }

2.3 交互功能实现

// 多指触控支持 void HandleTouchInput() { if (Input.touchCount == 1) { // 单指拖动 panOffset += Input.GetTouch(0).deltaPosition * zoomLevel; } else if (Input.touchCount == 2) { // 双指缩放 Touch t1 = Input.GetTouch(0); Touch t2 = Input.GetTouch(1); Vector2 prevPos1 = t1.position - t1.deltaPosition; Vector2 prevPos2 = t2.position - t2.deltaPosition; float prevDist = Vector2.Distance(prevPos1, prevPos2); float currDist = Vector2.Distance(t1.position, t2.position); zoomLevel *= currDist / prevDist; zoomLevel = Mathf.Clamp(zoomLevel, 0.1f, 10f); } } // 节点点击检测 void CheckNodeSelection(Vector2 mousePos) { foreach (var node in visibleNodes) { Rect nodeRect = new Rect( node.Position.x - NODE_SIZE/2, node.Position.y - NODE_SIZE/2, NODE_SIZE, NODE_SIZE); if (nodeRect.Contains(mousePos)) { ShowNodeInfo(node); break; } } }

三、功能扩展实践

3.1 智能告警系统

void AnalyzeCommonIssues() { // 检测循环依赖 foreach (var node in allNodes) { CheckCircularDependency(node, new HashSet<ABNode>()); } // 识别大体积重复资源 var sizeMap = new Dictionary<string, float>(); foreach (var node in allNodes) { float size = CalculateABSize(node.Name); foreach (var dep in node.GetAllDependencies()) { sizeMap[dep.Name] = sizeMap.ContainsKey(dep.Name) ? sizeMap[dep.Name] + size : size; } } // 标记高风险节点 foreach (var entry in sizeMap.Where(x => x.Value > WARNING_THRESHOLD)) { GetNode(entry.Key).MarkHighRisk(); } }

3.2 性能优化建议

csharpCopy Code

void GenerateOptimizationTips() { // 公共依赖提取建议 var commonDeps = allNodes .SelectMany(n => n.Dependencies) .GroupBy(d => d) .Where(g => g.Count() > COMMON_THRESHOLD) .OrderByDescending(g => g.Count()); foreach (var group in commonDeps) { Debug.Log($"建议将 {group.Key.Name} 提取为公共包，被 {group.Count()} 个AB依赖"); } // 包体拆分建议 var oversized = allNodes .Where(n => CalculateABSize(n.Name) > MAX_RECOMMEND_SIZE) .OrderByDescending(n => CalculateABSize(n.Name)); foreach (var node in oversized) { Debug.Log($"建议拆分 {node.Name}（当前大小：{CalculateABSize(node.Name)}MB）"); } }
