2022-04-18 introduction to unity 2 - how unity works

One 、 The toolbar

1. File operations ： New project , New scene , Project packaging, etc
2. Edit operation ： Object editing operations , Engineering setup , Engine settings
3. Resource operations ： It's basically the same as Project Right click relevant functions in the window
4. The object operation ： It's basically the same as Hierarchy Right click relevant functions in the window
5. Script operation ：Unity The script that comes with it , You can add scripts in each system
6. window ： Can open Unity Windows of each core system
7. help ： Check for updates , Version view function, etc

（ One ）File

（ Two ）Edit

​ File Important options in ：

​ BuildSetting（ Project release and packaging ）

​ Edit Important options in ：

​ Project Setting（ System settings of the project ）

​ Preferences（ Preferences , Programming software can be set ）

​ GameObject Important options in ：

​ MoveToView、Align With View、Align View to Selected（ Several functions of quick setting location ）

Two 、 Father and son

1. The child object changes as the parent object changes

2. Sub object Inspector Window Transform Information is relative to the parent object

3. Scene The role of the top

   • Pivot Will identify their own coordinates
   
   • Center It will identify the central coordinates of itself and its sub objects
   

3、 ... and 、 The reflex mechanism

（ One ） The nature of the objects in the scene

​ GameObject Class object is Unity The engine provides us with , As the foundation of all objects in the scene

​ An object appears in the game scene , Whether it's pictures 、 Model 、 Sound effect 、 Cameras and so on are attached to GameObject Object's

​ GameObject The object appears on the stage as a （3D scene ） The actor in , There must be a message indicating your location

​ Transform Is an essential script , Its essence is to send a script indicating the position to the actors

​ （ It's equivalent to using a Transform Class objects and GameObject Class object ）

（ Two ） The reflex mechanism

​ except Transform This is outside the standard script representing the position , We can work for this actor （GameObject） Relate various scripts （C# Script ）, Let it follow our script （ In code logic ） Order to deal with things

​ And the process of adding scripts for actors , Is using reflection new A new script object and actor （GameObject） Object to associate , Let them do what we ordered . for example ,

1. modify Inspector The palette Transform The content of

   Using the reflection ： Known objects , Class name , Variable name , Set the variable value for the object by reflection

2. After creating a new script , Add to a specified GameObject object

   Using the reflection ： Known class name , You can get all public members , So it can be in Inspector Create public field information on the panel

Four 、 Game scenario

​ The suffix of the game scene file is .unity

​ Its essence is a configuration file

​ Unity There is a mechanism to identify and deal with it

​ But the essence is to read out the relevant information of scene objects , Create objects by reflection and associate script objects

​ open .unity file , Get the following information ：

​ It can be seen that ,.unity The file stores all the configuration information in the scene .
