By: Harrison Ferrone

Overview of this book

Over the years, the Learning C# by Developing Games with Unity series has established itself as a popular choice for getting up to speed with C#, a powerful and versatile programming language that can be applied in a wide array of application areas. This book presents a clear path for learning C# programming from the ground up without complex jargon or unclear programming logic, all while building a simple game with Unity. This fifth edition has been updated to introduce modern C# features with the latest version of the Unity game engine, and a new chapter has been added on intermediate collection types. Starting with the basics of software programming and the C# language, you’ll learn the core concepts of programming in C#, including variables, classes, and object-oriented programming. Once you’ve got to grips with C# programming, you’ll enter the world of Unity game development and discover how you can create C# scripts for simple game mechanics. Throughout the book, you’ll gain hands-on experience with programming best practices to help you take your Unity and C# skills to the next level. By the end of this book, you’ll be able to leverage the C# language to build your own real-world Unity game development projects.

Time for action – accessing the current transform component

Since LearningCurve is already attached to the Main Camera, let's grab the Transform component from the Main Camera and store it in a public variable:

  1. Add a new public Transform type variable, called camTransform, to LearningCurve:
       private Transform camTransform;
  1. Initialize camTransform in Start using the GetComponent method from the GameObject class:
    • Use the this keyword, since LearningCurve is attached to the same GameObject component as the Transform component.
  1. Access and debug the localPosition property of camTransform using dot notation:
 void Start()
{
camTransform
= this.GetComponent<Transform>();
Debug.Log(camTransform.localPosition);

}

We've added an uninitialized private Transform variable at the top of LearningCurve and initialized it using the GetComponent method inside Start. GetComponent finds the Transform component attached to this...
