Question

我想创建一个空的GameObject，它是组件GameObject的子项。

实施例：我有一个简单的样条曲线，我使用子对象作为控制点。我有一个按钮来添加新的控制点，使用以下代码创建一个新对象，并且还应该将新的GameObject设置为脚本对象的子项。

public void addNewNode()
{
   var g = new GameObject();
   g.transform.parent = this.transform;
}

此实现不起作用，并且不显示检查器中的对象，我认为这意味着出错并且对象被破坏。

编辑：

为了测试父设置是否正常工作，我打印了g父变换的名称。它打印了正确的名称，所以我认为问题是设置父级没有反映在编辑器中。注意：除[CustomEditor()]脚本外，我还使用MonoBehaviour脚本，如果这会影响统一性。

编辑2 - 最小完整代码：

[CustomEditor(typeof(SplineManager))]
public class SplineManagerInspector : Editor {

public override void OnInspectorGUI()
{
    SplineManager spMngr = (SplineManager)target;

    // additional code to add public variables

    if (GUILayout.Button ("Add New Node")) {
        spMngr.addNewNode ();
        EditorUtility.SetDirty (target);
    }

    // code to add some public variables

    if (GUI.changed) {
        spMngr.valuesChanged ();
        EditorUtility.SetDirty (target);
    }
}
}


[RequireComponent (typeof(LineRenderer))]
public class SplineManager : MonoBehaviour
{
    public SplineContainer splineContainer = new SplineContainer ();
    public LineRenderer lineRenderer;
    private GameObject gObj;

    // additional code to deal with spline events/actions.

    public void addNewNode ()
    {
        Debug.Log ("new node");
        gObj = new GameObject ();
        gObj.transform.parent = this.gameObject.transform;  // this does not work... (shows nothing)
    }
}

Answer 1

public void addNewNode( GameObject parentOb)
{
    GameObject childOb = new GameObject("name");
    childOb.transform.SetParent(parentOb);
}

或

private GameObject childObj;
private GameObject otherObj;

public void addNewNode()
{
    childObj = new GameObject("name");
    // in case you want the new gameobject to be a child of the gameobject that your script is attached to
    childObj.transform.parent = this.gameObject.transform;
    // we can use .SetParent as well
    otherObj.transform.SetParent(childObj);
}

如何将新GameObject设置为Components GameObject的子节点？
