Math For Games Understanding Circles
Course Description
We are pleased to bring the first course in the Math for Games Series. We aim to bring you a complete focused course each month, centered around the math we use everyday in game development. This first course will dedicate itself to understanding the circle, using the Unity Mathf Class, Scene View gizmos and C#. By the end of this course you will have the knowledge to build your own circles, that can have a variable set of points, can be opened or closed, and how to set up the gizmos for displaying your circle.

Course Lessons

1. Drawing the Circle Points

Lesson 1, Drawing the Circle Points
To get started with this course, we are going to learn how to draw the points of a circle and display them in the Scene View. This will provide the foundation to our circle.

2. Drawing the Circle Lines

Lesson 2, Drawing the Circle Lines
With our circle up and running, let’s look at a way to connect the points of the circle with lines and display those lines.

3. Modifying the Radius and Offset

Lesson 3, Modifying the Radius and Offset
A circle wouldn’t be all that great if we could change its radius or offset. In Lesson 3 we are going to learn how we can add on these modifications to our current circle code.

4. Drawing a Triangle inside of the Circle

Lesson 4, Drawing a Triangle inside of the Circle
As a fun addition to our circle math course, we decided to go ahead and throw a triangle into the circle to show how the use of sine and cosine generate a circle, from a visual standpoint.

5. Added Bonus

We felt it proper to add in a couple more fun math exercises we can do with a circle. Lesson 5 will show you how to calculate the circumference (or the outside length of a circle) and the area of a circle.
