"Programming isn't about what you know; it's about what you can figure out . - Chris Pine

If you don't know anything about programming in general, writing code, writing scripts, or have no idea where to even begin, then this book is perfect for you. If you want to make games and need to learn how to write C# scripts or code, then this book is ideal for you.

Unity is a cross-platform development platform initially created for developing games but is now used for a wide range of things such as: architecture, art, children's apps, information management, education, entertainment, marketing, medical, military, physical installations, simulations, training, and many more.Unity takes a lot of the complexities of developing games and similar interactive experiences and looks after them behind the scenes so people can get on with designing and developing their games. These complexities include graphics rendering, world physics and compiling. More advanced users can interact and adapt them as needed but for beginners they need not worry about it.Games in Unity are developed in two halves; the first half -within the Unity editor, and the second half -using code, specifically C#. Unity is bundled with MonoDevelopor Visual Studio 2015 Communityfor writing C#.

Unity is equally suited to creating both 2D and 3D games. But whats the difference? When you create a new project in Unity, you have the choice to start in 2D or 3D mode. You may already know what you want to build, but there are a few subtle points that may affect which mode you choose.The choice between starting in 2D or 3D mode determines some settings for the Unity Editor -such as whether images are imported as textures or sprites. Dont worry about making the wrong choice though, you can swap between 2D or 3D mode at any time regardless of the mode you set when you created your project. Here are some guidelines which should help you choose.

3D games usually make use of three-dimensional geometry, with materials and textures rendered on the surface of these objects to make them appear as solid environments, characters and objects that make up your game world. The camera can move in andaround the scene freely, with light and shadows cast around the world in a realistic way. 3D games usually render the scene using perspective, so objects appear larger on screen as they get closer to the camera. For all games that fit this description, start in3Dmode.

Sometimes games use 3D geometry, but use an orthographic camera instead of perspective. This is a common technique used in games which give you a birds-eye view of the action, and is sometimes called 2.5D. If youre making a game like this, you should also use the editor in3Dmode, because even though there is noperspective, you will still be working with 3D models and assets. Youll need to switch yourcameraandscene viewtoOrthographicthough.(scenes above fromSynty StudiosandBITGEM)

Many 2D games use flat graphics, sometimes called sprites, which have no three-dimensional geometry at all. They are drawn to the screen as flat images, and the games camera has no perspective. For this type of game, you should start the editor in 2D mode.

Some 2D games use 3D geometry for the environment and characters, but restrict thegameplayto two dimensions. For example, the camera may show a side scrolling view and the player can only move intwo dimensions, but game still uses 3D models for the obstacles and a 3D perspective for the camera. For these games, the 3D effect may serve a stylistic rather than functional purpose. This type of game isalsosometimes referred to as 2.5D. Although the gameplay is 2D, you will mostly be manipulating 3D models to build the game so you should start the editor in 3D mode.

Perhaps the gaming industry is one of the most difficult industries in this era, and that is in many ways that start with technical challenges, passing through an audience that is difficult to satisfy and ruthless even for the major companies if their products are not at the required level, and not an end to fierce competition and high failure rates and the difficulty of achieving profits that cover high production costs.

On the other hand, there are features of this industry that make survival in it possible. On the technical side, for example, the vast majority of games are not free of similar functions and repetitive patterns of data processing, which makes the reuse of the software modules of previous games in order to create new games possible. This, in turn, contributes to overcoming technical obstacles and shortening time and effort.

When you talk about making a game, you are here to mention the big process that involves dozens and possibly hundreds of tasks to accomplish in many areas. Making a game means producing, marketing, and publishing it, and all the administrative, technical, technical, financial, and legal procedures and steps involved in these operations. However, what is important for us in this series of lessons is the technical aspect which is game development, which is the process of building the final software product with all its components. This process does not necessarily include game design, as the design process has a broader perspective and focuses on such things as the story, the general characteristic of the game, the shapes of the stages and the nature of the opponents, as well as the rules of the game, its goals and terms of winning and losing.

Returning to the game development process, we find that many specializations and skills contribute to this process. There are painters, model designers, animation technicians, sound engineers, and director, in addition to - of course - programmers. This comprehensive view is important to know that the programmer's role in producing the game is only an integral role for the roles of other team members, though this image is beginning to change with the emergence of independent developers Indie Developers who perform many tasks besides programming.
