通过左上角的按钮可以动态创建物体并添加

对应的C# 脚本如下：

using UnityEngine;using System.Collections;

public class CreateNew : MonoBehaviour {

// Use this for initializationvoid Start () {}

void OnGUI(){if(GUILayout.Button("创建立方体",GUILayout.Height(50)))  {GameObject objCube = GameObject.CreatePrimitive(PrimitiveType.Cube);objCube.AddComponent();objCube.name = "Cube";// objCube.renderer.material.color = Color.blue;objCube.transform.position = new Vector3(0.0f,7.0f,0.0f);}

if (GUILayout.Button ("创建球体", GUILayout.Height (50))) {GameObject objSpere = GameObject.CreatePrimitive(PrimitiveType.Sphere);objSpere.AddComponent();objSpere.name = "Sphere1";objSpere.transform.position = new Vector3(2.0f,7.0f,0.0f);// objSpere.AddComponent();}}}
