# 4.定位场景中的对象4. Positioning objects in the scene

## 目标Objectives

• 了解如何定位场景中的对象Learn how to position objects in the scene
• 了解如何使用 MRTK 的网格对象集合功能Learn how to use MRTK's Grid Object Collection feature

## 创建父对象Creating the parent object

• 位置：X = 0, Y = -0.6, Z = 2Position: X = 0, Y = -0.6, Z = 2
• 旋转：X = 0, Y = 0, Z = 0Rotation: X = 0, Y = 0, Z = 0
• 缩放：X = 1，Y = 1，Z = 1Scale: X = 1, Y = 1, Z = 1

• 位置：X = 0, Y = -0.005, Z = 0Position: X = 0, Y = -0.005, Z = 0
• 旋转：X = 0, Y = 0, Z = 0Rotation: X = 0, Y = 0, Z = 0
• 缩放：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
• 旋转：X = 0, Y = -135, Z = 0Rotation: X = 0, Y = -135, Z = 0
• 缩放：X = 1，Y = 1，Z = 1Scale: X = 1, Y = 1, Z = 1

## 组织集合中的对象Organizing objects in a collection

• 位置：X = 0, Y = 0.06, Z = 0Position: X = 0, Y = 0.06, Z = 0
• 旋转：X = 0, Y = 90, Z = 0Rotation: X = 0, Y = 90, Z = 0
• 缩放：X = 1，Y = 1，Z = 1Scale: X = 1, Y = 1, Z = 1

• 排序类型：按字母顺序Sort Type: Alphabetic
• 布局：水平Layout: Horizontal
• 单元格宽度：0.25Cell Width: 0.25
• 到父项的距离：0.38Distance from parent: 0.38
