Question

我正在尝试为我的Unity项目创建一个新元素但是我需要统一来将我的整个对象渲染为UI对象如何实现这一点。到目前为止我目前的剧本。

using UnityEditor;
using UnityEngine;

public class OptionSwitch : MonoBehaviour {

    [MenuItem ("GameObject/UI/Switch")]
    static void Switch(){
        GameObject go = new GameObject("switch");
        go.transform.parent = Selection.activeTransform;
        go.transform.localPosition = Vector3.zero;
    }
}

它将是一个选项开关，文本框两侧有一个按钮，表示活动选项。

我做了更多研究并提出了这段代码。

using UnityEditor;
using UnityEngine;

public class OptionSwitch : MonoBehaviour {

    [MenuItem ("GameObject/UI/Switch")]
    static void Switch(){

        if (GameObject.Find ("Canvas") != null) {

            // Define Components
            GameObject Canvas   = GameObject.Find("Canvas");
            GameObject Switch   = new GameObject("Switch");
            GameObject Previous = new GameObject("Previous Button");
            GameObject Next     = new GameObject("Next Button");
            GameObject Text     = new GameObject("Textbox");


            // Place Switch
            Switch.transform.parent = Canvas.transform;
            Switch.transform.localPosition = Vector3.zero;

            // Place Previous Button
            Previous.transform.parent = Switch.transform;
            Previous.transform.localPosition = Vector3.zero;

            // Place Text Field
            Text.transform.parent = Switch.transform;
            Text.transform.localPosition = Vector3.zero;

            // Place Next Field
            Next.transform.parent = Switch.transform;
            Next.transform.localPosition = Vector3.zero;
        }
    }
}

您必须先找到Canvas GameObject。 Canvas GameObject附加了Canvas个组件。因此，您使用FindObjectOfType来查找Canvas组件。然后，您可以将该Canvas脚本的实例转换为GameObject。您原始代码的修复程序：

[MenuItem("GameObject/UI/Switch")]
static void Switch()
{
    //Create new GameObject
    GameObject go = new GameObject("switch");


    //Find Canvas in the Scene
    Canvas canvas = (Canvas)GameObject.FindObjectOfType(typeof(Canvas));

    //Get Canvas GameObject
    GameObject canvasGameObject = canvas.gameObject;

    //Make the new GameObject child of the Canvas
    go.transform.parent = canvasGameObject.transform;
    go.transform.localPosition = Vector3.zero;

    //Change the new GameObject Layer to UI
    go.layer = 5; //Or go.layer = canvasGameObject.layer;

    //Add Rect Transform to it
    go.AddComponent<RectTransform>();
}

如何创建对象作为Canvas的父级
