# 4.將物件置放在場景中4. Positioning objects in the scene

## 目標Objectives

• 了解如何將物件放置在場景中Learn how to position objects in the scene
• 了解如何使用 MRTK 的網格物件集合功能Learn how to use MRTK's Grid Object Collection feature

## 建立父物件Creating the parent object

• 位置：X = 0、Y = -0.6、Z = 2Position: X = 0, Y = -0.6, Z = 2
• 旋轉：X = 0、Y = 0、Z = 0Rotation: X = 0, Y = 0, Z = 0
• 縮放：X = 1、Y = 1、Z = 1Scale: X = 1, Y = 1, Z = 1

## 新增教學課程 PrefabAdding the tutorial prefabs

Prefab 是預先設定且儲存為 Unity 資產的 GameObject，可以在整個專案中重複使用。A prefab is a pre-configured GameObject stored as a Unity Asset and can be reused throughout your project.

• 位置：X = 0、Y = -0.005、Z = 0Position: X = 0, Y = -0.005, Z = 0
• 旋轉：X = 0、Y = 0、Z = 0Rotation: X = 0, Y = 0, Z = 0
• 縮放：X = 1.2、Y = 0.01、Z = 1.2Scale: X = 1.2, Y = 0.01, Z = 1.2

• 位置：X = -0.1、Y = 0、Z = 0Position: X = -0.1, Y = 0, Z = 0
• 旋轉：X = 0、Y = -135、Z = 0Rotation: X = 0, Y = -135, Z = 0
• 縮放：X = 1、Y = 1、Z = 1Scale: X = 1, Y = 1, Z = 1

## 組織集合中的 3D 物件Organizing objects in a collection

• 位置：X = 0、Y = 0.06、Z = 0Position: X = 0, Y = 0.06, Z = 0
• 旋轉：X = 0、Y = 90、Z = 0Rotation: X = 0, Y = 90, Z = 0
• 縮放：X = 1、Y = 1、Z = 1Scale: X = 1, Y = 1, Z = 1

• 排序類型：字母順序Sort Type: Alphabetic
• 版面配置：水平Layout: Horizontal
• 儲存格寬度：0.25Cell Width: 0.25
• 與父系的距離：0.38Distance from parent: 0.38
