If you create a script with the above text in your code editor and then come back to Unity and assign the script to a GameObject, you’ll see that you can access and see the light variable declared as public in the Inspector, but you can’t see the private one. When we’re declaring your variables there are several visibility types, but the two most important ones are public and private. Here’s a script with some sample code in it (based on the Coding in Unity for the Absolute Beginner tutorial): Starting with 2018.1, you can also use Visual Studio for Unity Community, or other text editors such as Visual Studio, Notepad, or Sublime text. If you’re using a version of Unity until 2017.3, you’ll notice that it has a text editor called MonoDevelop: it can help us complete our code, it’ll let us know if we’re writing a wrong piece of code, and allows us to take shortcuts. Like any language, scripting languages have syntax, or parts of speech, and the primary parts are called variables, functions, and classes. All the languages that Unity operates with are object-oriented scripting languages. The language that’s used in Unity is called C# (pronounced C-sharp). And, it’s through this language that we can talk to the engine and give it our instructions. Scripts are written in a special language that Unity can understand. You direct Unity with the instructions that you write in your scripts, and Unity executes them frame after frame as fast as it can.Īchieving 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.Ī script must be attached to a GameObject in the scene in order to be called by Unity. It’s running single discrete frames, one after another. If you think about television, where, for example in North America, you have 29.5 frame/sec, Unity needs to do the same thing. For example, it reads through the lights, the meshes, what the behaviors are, and it processes all of this information for you. It reads all of the data that’s in a game scene. Instead, you focus on the gameplay in your scripts. you created a running app, you should realize that in Unity you don’t need to create the code that runs the application, because Unity does it for you. If you’ve done some pure programming, e.g. Now, scripting in Unity is different from pure programming.
