From c40f3d03571a302ba7834c87a6d686885311d4b0 Mon Sep 17 00:00:00 2001 From: David Sarno Date: Tue, 2 Sep 2025 18:45:30 -0700 Subject: [PATCH] feat: implement robust ComponentResolver for assembly definitions MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Replace Assembly.LoadFrom with already-loaded assembly search - Prioritize Player assemblies over Editor assemblies using CompilationPipeline - Support both short names and fully-qualified component names - Add comprehensive caching and error handling with disambiguation - Use Undo.AddComponent for proper editor integration - Handle ReflectionTypeLoadException safely during type enumeration - Add fallback to TypeCache for comprehensive type discovery in Editor Fixes component resolution across custom assembly definitions and eliminates "Could not load the file 'Assembly-CSharp-Editor'" errors. Tested with: - Built-in Unity components (Rigidbody, MeshRenderer, AudioSource) - Custom user scripts in Assembly-CSharp (TicTacToe3D) - Custom assembly definition components (TestNamespace.CustomComponent) - Error handling for non-existent components 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- .../Scripts/TestAsmdef/CustomComponent.cs | 18 ++ .../TestAsmdef/CustomComponent.cs.meta | 2 + .../Scripts/TestAsmdef/TestAsmdef.asmdef | 14 ++ .../Scripts/TestAsmdef/TestAsmdef.asmdef.meta | 7 + UnityMcpBridge/Editor/Tools/ManageAsset.cs | 44 +--- .../Editor/Tools/ManageGameObject.cs | 196 ++++++++++++++---- 6 files changed, 193 insertions(+), 88 deletions(-) create mode 100644 TestProjects/UnityMCPTests/Assets/Scripts/TestAsmdef/CustomComponent.cs create mode 100644 TestProjects/UnityMCPTests/Assets/Scripts/TestAsmdef/CustomComponent.cs.meta create mode 100644 TestProjects/UnityMCPTests/Assets/Scripts/TestAsmdef/TestAsmdef.asmdef create mode 100644 TestProjects/UnityMCPTests/Assets/Scripts/TestAsmdef/TestAsmdef.asmdef.meta diff --git a/TestProjects/UnityMCPTests/Assets/Scripts/TestAsmdef/CustomComponent.cs b/TestProjects/UnityMCPTests/Assets/Scripts/TestAsmdef/CustomComponent.cs new file mode 100644 index 0000000..b38e518 --- /dev/null +++ b/TestProjects/UnityMCPTests/Assets/Scripts/TestAsmdef/CustomComponent.cs @@ -0,0 +1,18 @@ +using UnityEngine; + +namespace TestNamespace +{ + public class CustomComponent : MonoBehaviour + { + [SerializeField] + private string customText = "Hello from custom asmdef!"; + + [SerializeField] + private float customFloat = 42.0f; + + void Start() + { + Debug.Log($"CustomComponent started: {customText}, value: {customFloat}"); + } + } +} \ No newline at end of file diff --git a/TestProjects/UnityMCPTests/Assets/Scripts/TestAsmdef/CustomComponent.cs.meta b/TestProjects/UnityMCPTests/Assets/Scripts/TestAsmdef/CustomComponent.cs.meta new file mode 100644 index 0000000..7d94964 --- /dev/null +++ b/TestProjects/UnityMCPTests/Assets/Scripts/TestAsmdef/CustomComponent.cs.meta @@ -0,0 +1,2 @@ +fileFormatVersion: 2 +guid: 78ee39b9744834fe390a4c7c5634eb5a \ No newline at end of file diff --git a/TestProjects/UnityMCPTests/Assets/Scripts/TestAsmdef/TestAsmdef.asmdef b/TestProjects/UnityMCPTests/Assets/Scripts/TestAsmdef/TestAsmdef.asmdef new file mode 100644 index 0000000..04cfdce --- /dev/null +++ b/TestProjects/UnityMCPTests/Assets/Scripts/TestAsmdef/TestAsmdef.asmdef @@ -0,0 +1,14 @@ +{ + "name": "TestAsmdef", + "rootNamespace": "TestNamespace", + "references": [], + "includePlatforms": [], + "excludePlatforms": [], + "allowUnsafeCode": false, + "overrideReferences": false, + "precompiledReferences": [], + "autoReferenced": true, + "defineConstraints": [], + "versionDefines": [], + "noEngineReferences": false +} \ No newline at end of file diff --git a/TestProjects/UnityMCPTests/Assets/Scripts/TestAsmdef/TestAsmdef.asmdef.meta b/TestProjects/UnityMCPTests/Assets/Scripts/TestAsmdef/TestAsmdef.asmdef.meta new file mode 100644 index 0000000..21f1fe3 --- /dev/null +++ b/TestProjects/UnityMCPTests/Assets/Scripts/TestAsmdef/TestAsmdef.asmdef.meta @@ -0,0 +1,7 @@ +fileFormatVersion: 2 +guid: 72f6376fa7bdc4220b11ccce20108cdc +AssemblyDefinitionImporter: + externalObjects: {} + userData: + assetBundleName: + assetBundleVariant: diff --git a/UnityMcpBridge/Editor/Tools/ManageAsset.cs b/UnityMcpBridge/Editor/Tools/ManageAsset.cs index bef4f9a..a05931f 100644 --- a/UnityMcpBridge/Editor/Tools/ManageAsset.cs +++ b/UnityMcpBridge/Editor/Tools/ManageAsset.cs @@ -201,7 +201,7 @@ namespace MCPForUnity.Editor.Tools "'scriptClass' property required when creating ScriptableObject asset." ); - Type scriptType = FindType(scriptClassName); + Type scriptType = ComponentResolver.TryResolve(scriptClassName, out var resolvedType, out var error) ? resolvedType : null; if ( scriptType == null || !typeof(ScriptableObject).IsAssignableFrom(scriptType) @@ -355,7 +355,7 @@ namespace MCPForUnity.Editor.Tools { // Find the component on the GameObject using the name from the JSON key // Using GetComponent(string) is convenient but might require exact type name or be ambiguous. - // Consider using FindType helper if needed for more complex scenarios. + // Consider using ComponentResolver if needed for more complex scenarios.
