Which is the best technology? Why should we use MVC? Why should we use AngularJS? Which is the best technology Now- a-days, there are lots of new technologies in the world, so we may have confusion to choose the right and best technology to build our application. We can reuse the same Service for other communication devices mobile, iPad etc.

We get the struggle. This should get you covered in the following areas: the very basics of coding, like variables, functions and classes, and how to use them. What is scripting in Unity?
Now, scripting in Unity is different from pure programming. Instead, you focus on the gameplay in your scripts. Unity runs in a big loop. For example, it reads through the lights, the meshes, what the behaviors are, and it processes all of this information for you.
If you think about television, where, for example in North America, you have You direct Unity with the instructions that you write in your scripts, and Unity executes them frame after frame as fast as it can. Achieving a high frame rate means not only your game will look more fluid, but your scripts will also be executed more often, making controls more responsive. What languages can you use in Unity? A script must be attached to a GameObject in the scene in order to be called by Unity.
Scripts are written in a special language that Unity can understand. All the languages that Unity operates with are object-oriented scripting languages. Like any language, scripting languages have syntax, or parts of speech, and the primary parts are called variables, functions, and classes. Starting with What do these do? Variables start with a lowercase letter. Functions are collections of code that compare and manipulate these variables. Functions start with an uppercase letter. We organise code in functions so that they can be easily reused multiple times in different parts of the program.
Classes are a way to structure code to wrap collections of variables and functions together to create a template that defines the properties of an object. Scripting is primarily comparing these objects and their current states and values.
Variables In Unity, the scripts start by laying out the tools that you need at the top, and this is usually by declaring variables.
So, that means other people can access it and change its value. There are many reasons to choose between private or public. Private variables allow your code to be cleaner, since you know that the value of those variables can be changed only inside that class.
This makes debugging and maintaining the code easier. However, if you want objects to communicate between themselves you need some variables or functions to be public. Another important aspect of variables is the type. A type defines what kind of value is the variable holding in memory, e. Unity needs to know what type of object it is so that it knows how to handle it.
Another important thing about variables is the name. In C , the naming convention is camelCase: you start with a lowercase letter and add words, without spaces, starting with a capital letter, e. When Unity compiles the script, it makes public variables visible in the editor. See the image below from the inspector. Functions Scripts manipulate the variables by using functions. There are a number of functions that run automatically inside Unity.
See below: Awake is called only once when the GameObject with that component is instantiated. If a GameObject is inactive, then it will not be called until it is made active.
However, Awake is called even if the GameObject is active but the component is not enabled with the little checkbox next to its name. You can use Awake to initialize all the variables that you need to assign a value to. Start - like Awake, Start will be called if a GameObject is active, but only if the component is enabled. For more information on the differences with Awake, see this video. Update is called once per frame. This is where you put code to define the logic that runs continuously, like animations, AI, and other parts of the game that have to be constantly updated.
FixedUpdate is when you want to do physics work. Unity will look at all of the game objects, find all of the Updates, and call the LateUpdates. This is good for things like the camera.
Writing functions When writing a function, remember that functions start with the returned type of the function at the beginning, followed by the name of the function, and then the parameters in the parentheses if any.
Function names start with a capital letter and the body of the function goes between the curly brackets. Functions can do calculations and then return a value. You can ask a function to do something, process the information, then return an answer. If you use the type "void", then they are not returning anything. Classes Classes are collections of these variables and functions. For example, this script is a class: Bear in mind that the class name must match the file name of the C script for it to work.
And then to be attached to a GameObject, it has to derive from another class called MonoBehaviour which is automatically put there for you when you first create a script. Classes can also be public or private. In Unity, if you create a custom class, like in the example below, you have to ask it to serialize it. This means that it will be converted into simple data that Unity can look at in the inspector.
Variables, functions, and classes are just the basics of starting with coding in Unity.
