Hierarchy Viewer allows you to debug and optimize your user interface. It provides a visual representation of the layout’s View hierarchy (the Layout View) and a magnified inspector of the display (the Pixel Perfect View).
To start Hierarchy Viewer, enter the following command from the SDK tools/ directory:
hierarchyviewer

Hierarchy窗口

父子化

Hierarchy窗口中的列表是项目中的 “对象”。这些对象一一对应着Scene窗口中的对象。

但是在Hierarchy窗口中有一个显著的特征：父子化的列表形式。

父子化的主要表现的形式是：子对象的Transform或者RectTransform组件属性会根据父对象的Transform或者RectTransformation组件属性变化而变化。

比如：

父对象的Transform的Position的X属性为3时，子对象的Transform的Position的X属性会自动加3。

父对象的Transform的Rotation的X属性为30时，子对象的Transform的Rotation的X属性会自动加30。

父对象的Transform的Scale的X属性为3时，子对象的Transform的Scele的X属性会自动乘以3。

设置位置

我们可以在Hierarchy窗口中拖动以改变Hierarchy窗口对象的顺序或者父子关系。

在此图中，Object 4（选定对象）被拖到目标父对象 Object 1（以蓝色胶囊形状突出显示）上。

字母数字排序

Hierarchy 窗口中对象的顺序可以更改为字母数字顺序。在菜单栏中，选择 Edit > Preferences（在 Windows 中）或者选择 Unity > Preferences（在 OS X 中），启动 Preferences 窗口。选中 Enable Alpha Numeric Sorting。

选中此复选框时，Hierarchy 窗口的右上角会出现一个图标，允许在 Transform 排序（默认值）或 Alphabetic 排序之间切换。

Tips：Hierarcyh窗口中的对象和Scene窗口中的显示的先后顺序没有关系，对象间的互相遮挡是因为对象离摄像机的远近关系形成。

Different Kinds of Memory

Fast: ~2ns access time
Expensive, high area requirement

~$5.0 per megabyte$0.13 for LC2
$20000 for MIPS DRAM (transistor and capacitor) Slower: ~60ns access time Must stall for dozens of cycles on each memory load Less expensive than SRAM ~$0.004 per megabyte
$0.00 for LC2$16 for MIPS/Pentium-IV/Athlon-XP

Flash (floating gate transistors)

Slower still: ~250ns access time

Must stall for dozens of cycles on each memory load

Less expensive than SRAM

~$0.0012 per megabyte$0.00 for LC2
$4.9 for MIPS/Pentium-IV/Athlon-XP Non-volatile Disks (Mechanical, Giant Magnetoresistance GMR) Obnoxiously slow: 3,000,000ns (3 ms) access time Cheap ~$0.000043 per megabyte
$0.00 LC2$0.18 for MIPS

Non-volatile

Memory Hierarchy Goals

Hierarchical Memory

A small array of SRAM

Small so fast and cheap
Cache (hopefully covers most loads and stores)

A larger amount of DRAM

Cheaper than SRAM, faster than flash/disk
Main Memory

A lot of flash and/or disk

Non-volatile. Cheap. Big
flash and/or disk
Non-volatile. Cheap. Big
