Hello. My name is Ken Geary, and in these lessons you will learn about creating code using C Sharp and Unity. C Sharp is a programming language that is commonly used in game development, including the Unity Game Engine. Within Unity, C Sharp is used to write scripts that control game behavior and interaction. These scripts are attached to game objects such as vehicles, enemies, and pickup items, and can be used to handle player input, physics, animations, audio, and other aspects of the game. Open the My Level scene. Go to assets scenes and double click My Level. We will clean up our layout by opening the Top Window menu, selecting Layouts and Default. Let's confirm that Visual Studio is our editor for Unity. Open, edit, then preferences. Click External Tools next to the external script editor, visual Studio should be listed. If not, click the drop down menu and select Visual Studio. This is important because the installation of Visual Studio has options added that use Unity code hints and helpers to make scripting for Unity easier. Close the preferences panel. To prepare for writing code, let's make a Scripts folder. Open the Assets folder. Right click. Create a scripts folder. Open up the scripts. Folder. To create a C sharp script, open the Assets menu. At the top, select Create, then select C Sharp script. We'll name the script Hello World. If you noticed, I made the H and W capital letters. This is called Camel Case, and it makes it very easy to read the words as one word. We do need to stop here and review something that's very important. You absolutely need to name a script as soon as it is created. Do not click away. If you do, click away and rename it afterwards. The script will be looking for unnamed script. Please check each script as follows select the script in the Project panel. In the Inspector, you will see a preview of the C Sharp script code. Confirm that the line that says Public Class is Hello World and spelled exactly as you name the script in the project panel, including the capital H and capital W. If there is a mismatch in your script, the script will not work properly. In Unity editor. Most coding errors for beginners is misspellings. Computer code is very unforgiving, and these exact spellings of names you give the variables and functions in your code. The second common issue with Beginners is that you can write many lines of correct code save your script, but when you hit Play in Unity Editor, nothing happens. That is because you need to add a script to any game object in the scene. You can attach a script to a prefab camera, light, et cetera. You can even add a script to an empty game object. This is used frequently for overall game control, such as health and score status. Right click in the Hierarchy panel and create an empty game object. Name it. Hello. To add a script to a game object. You can simply drag the script from the Project panel into the Inspector panel. Just make sure the proper game object is selected first. You can also add a script using the Add component button, and then search for the script and add it that way. Follow this process for all scripts you create and you will be off to a great start. One other note even if we do not save this scene, the script is already saved and available, much like when we created Prefabs Save My Level. And in the next lesson, we're going to learn how to start writing code using C sharp and unity. Thanks for watching.

Course Description

In these lessons, you will learn how to code C# (C Sharp) scripts to control GameObjects in Unity using the Visual Studio Editor. Scripting, or coding, is a critical aspect of game development in Unity, or any game engine, allowing users to create custom game mechanics and functionality to enhance gameplay. We’ll show you how Unity provides a powerful scripting API, and you’ll discover what you can achieve with it.

In order to create a game or interactive project in Unity, you will need to create some code to control actions and objects in your scene. Coding can seem overwhelming at first glance, but we will explain what C# is and how to create basic scripts to start building your skills to create more involved code. We’ll also cover syntax and error handling so that, when you’re done, you will have a basic interaction between an object and pickup Prefabs.
