Unity 资产操作

通过 run_unity_python 在 Unity Editor 中管理资产（Asset）。

调用方式

run_unity_python(code="<C# 代码>")

操作示例

搜索资产（按类型）

// type: Prefab / Material / Texture2D / AudioClip / AnimationClip / Script ...
var guids = UnityEditor.AssetDatabase.FindAssets("t:Prefab", new[] { "Assets" });
var result = new System.Collections.Generic.List<object>();
foreach (var guid in guids) {
    var path = UnityEditor.AssetDatabase.GUIDToAssetPath(guid);
    result.Add(new { guid = guid, path = path, name = System.IO.Path.GetFileNameWithoutExtension(path) });
}
return Newtonsoft.Json.JsonConvert.SerializeObject(new { count = guids.Length, assets = result });

按名称搜索资产

// 搜索名为 "Player" 的所有资产
var guids = UnityEditor.AssetDatabase.FindAssets("Player", new[] { "Assets" });
var result = new System.Collections.Generic.List<object>();
foreach (var guid in guids) {
    var path = UnityEditor.AssetDatabase.GUIDToAssetPath(guid);
    var type = UnityEditor.AssetDatabase.GetMainAssetTypeAtPath(path);
    result.Add(new { path = path, type = type?.Name ?? "Unknown" });
}
return Newtonsoft.Json.JsonConvert.SerializeObject(result);

在场景中实例化 Prefab

// prefabPath: Assets/Prefabs/Enemy.prefab
var prefab = UnityEditor.AssetDatabase.LoadAssetAtPath<UnityEngine.GameObject>("Assets/Prefabs/Enemy.prefab");
if (prefab == null) return "{\"error\": \"Prefab not found\"}";
var instance = (UnityEngine.GameObject)UnityEditor.PrefabUtility.InstantiatePrefab(prefab);
instance.name = "Enemy";
instance.transform.position = UnityEngine.Vector3.zero;
UnityEditor.Undo.RegisterCreatedObjectUndo(instance, "Instantiate Prefab");
return Newtonsoft.Json.JsonConvert.SerializeObject(new {
    instantiated = true,
    name = instance.name,
    instanceId = instance.GetInstanceID()
});

将 GameObject 保存为 Prefab

// goName: 场景中的 GameObject 名, savePath: Assets/Prefabs/MyPrefab.prefab
var go = UnityEngine.GameObject.Find("MyObject");
if (go == null) return "{\"error\": \"GameObject not found\"}";
var prefab = UnityEditor.PrefabUtility.SaveAsPrefabAsset(go, "Assets/Prefabs/MyPrefab.prefab");
return Newtonsoft.Json.JsonConvert.SerializeObject(new {
    created = true,
    path = UnityEditor.AssetDatabase.GetAssetPath(prefab)
});
