Practical Unity3D Development: From recognition interface to game demo (1)

As we all know, Unity3D is a game development tool that can easily create multiple platforms and is a fully integrated professional game engine. In the current version, its powerful game production functions have been achieved to the point where people are stunned. Especially the first-person war game it created in version 3.0, the image quality is no inferior to mainstream first-person shooting games such as crossing FireWire and battlefield king. For the Display Effect in the Demo:

Seeing such a brilliant effect, let me immediately enter the wonderful Unity3D world! Download Unity3D on the official website.

After the download, you must register an email on the official website to get a 30-day trial. If you are satisfied with this software after the trial, you can continue to use it after purchase. Of course, if you purchase the Pro version of Unity3D, more features will be available.
Chapter 1Basic Unity3D interface Introduction

The basic Unity3D interface is very simple, and almost all the editing functions can be implemented in several windows. The main interface 1.1 is shown in:


Scenario panel: This panel is an Unity3D editing panel. You can drag and drop all your models, lights, and other materials to the current scene. Build the scenes that can be presented in the game.
Animation panel: Unlike the scene panel, this Panel is used to render scenes in the scene panel. This Panel cannot be used for editing, but can render the complete animation effect. The displayed content depends on the scene camera settings.
Hierarchical list bar: The main function of this Panel is to display all objects in the scene panel.
Project File bar: This panel displays a list of all resources in the project file. In addition to models, materials, fonts, etc., it also includes various scenario files of the project.
Object Property bar: This Panel bar displays the inherent attributes of any object, including 3D coordinates, rotation volume, scaling size, script variables and objects.
Scenario adjustment tool: You can change the scene angle, the world and local coordinates of the object during editing, the normal center of the object, the Coordinate Position of the object in the scene, and the scaling size.

Menu Bar: Next I will focus on the menu bar.

The menu bar contains eight menu options: file, Edit, Assets resource, GameObject game object, Component, Terrain, Window, and Help ].

Each menu option has its own sub-menu, which is summarized as follows:

1. File]

Name	Description
New Scene	Create a new scenario. Just like one scenario in a game, Unity3D provides users with convenient scenario management, allowing users to create their desired scenarios as they wish. Then link each scenario to form a complete game.
Open Scene	Open a created scenario
Save Scene	Save current scenario
Save Scene	Save the current scenario
New Project	Create a new project. To create your own game, the first step is to create a project that belongs to the game. This project is the foundation of all elements. With the project, you can add your own scenarios in the project.
Open Project	Open a created Project
Save Project	Save current project
Build Setting	Project compilation settings. In the compilation settings option, you can select the platform where the game is located and manage various scenarios in the project. You can add the current scenario to the compilation queue of the project. In the Player Settings option, you can set the program icon, resolution, and startup screen.
