通过 run_unity_python 在 Unity Editor 中创建、修改、删除 GameObject。

调用方式

run_unity_python(code="<C# 代码>")

操作示例

获取当前选中的 GameObject

var selection = UnityEditor.Selection.gameObjects;
var result = new System.Collections.Generic.List<object>();
foreach (var go in selection) {
    result.Add(new {
        name = go.name,
        instanceId = go.GetInstanceID(),
        active = go.activeSelf,
        tag = go.tag,
        layer = UnityEngine.LayerMask.LayerToName(go.layer),
        position = new { x = go.transform.position.x, y = go.transform.position.y, z = go.transform.position.z }
    });
}
return Newtonsoft.Json.JsonConvert.SerializeObject(new { count = selection.Length, objects = result });

创建空 GameObject

// name: 要创建的对象名称
var go = new UnityEngine.GameObject("NewObject");
UnityEditor.Undo.RegisterCreatedObjectUndo(go, "Create GameObject");
UnityEditor.Selection.activeGameObject = go;
return Newtonsoft.Json.JsonConvert.SerializeObject(new {
    created = true,
    name = go.name,
    instanceId = go.GetInstanceID()
});

创建带基础组件的 GameObject（Cube/Sphere/Capsule 等）

// primitive: Cube / Sphere / Capsule / Cylinder / Plane / Quad
var go = UnityEngine.GameObject.CreatePrimitive(UnityEngine.PrimitiveType.Cube);
go.name = "MyCube";
UnityEditor.Undo.RegisterCreatedObjectUndo(go, "Create Primitive");
return Newtonsoft.Json.JsonConvert.SerializeObject(new { created = true, name = go.name });

删除 GameObject

// 按名称找到并删除
var go = UnityEngine.GameObject.Find("TargetObject");
if (go != null) {
    UnityEditor.Undo.DestroyObjectImmediate(go);
    return "{\"deleted\": true}";
}
return "{\"deleted\": false, \"error\": \"GameObject not found\"}";

复制 GameObject

var go = UnityEngine.GameObject.Find("SourceObject");
if (go == null) return "{\"error\": \"Source not found\"}";
var copy = UnityEngine.Object.Instantiate(go);
copy.name = go.name + "_Copy";
UnityEditor.Undo.RegisterCreatedObjectUndo(copy, "Duplicate GameObject");
return Newtonsoft.Json.JsonConvert.SerializeObject(new { duplicated = true, newName = copy.name });
