Read Texture Data from C# Scripts

In this Unity tutorial you'll learn how to sample texture data from within your C# scripts and do something based on the sampled result. Specifically today we'll be using the grayscale value of the colors to choose a weighted random pixel. Once we know that we'll be updating a virtual texture on a SpriteRenderer to show us the bounds of where we were sampling and the specific pixel sampled each time.

Reading texture data in your scripts has a wide variety of applications in Unity. From Editor Scripting to show brushes, to runtime weighted bullet spread there's as many options as you can come up with!
