Unity 编辑器开发(Button)_unity点击button生成物体

GUILayout.Button

记录使用GUILayout.Button在编辑器绘制Button按钮

创建脚本UIEditor.cs

using System.Collections;
using System.Collections.Generic;
using UnityEditor;
using UnityEngine;

[CustomEditor(typeof(TestUI))]
public class UIEditor : Editor
{
    public override void OnInspectorGUI()
    {
        DrawDefaultInspector();
        TestUI test = (TestUI)target;
        if (GUILayout.Button("创建对象"))
        {
            test.CreateObject();
            Debug.Log("创建对象成功");
        }

    }
}

创建脚本TestUI.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class TestUI : MonoBehaviour
{
    GameObject image;
    Vector3 Vec=new Vector3(50,490,0);
    int index = 0;
    Transform parent;
    private void Start()
    {
        image = Resources.Load<GameObject>("Object/image");
        parent= GameObject.Find("Canvas").transform;
    }
    public void CreateObject()
    {
        GameObject img=Instantiate(image,Vec+new Vector3(index*150,0,0),Quaternion.identity);
        img.transform.parent = parent;
        index++;
    }
}

将脚本挂载在场景中，如图所示：

将物体image制作成预制体，放置于Resource文件夹下的Object文件夹中

运行，点击按钮，就能直接生成物体
