Unity 5 2D: Texture Rendering

Unity developers use textures all the time. This course explains how textures work under the hood at the pixel level, so you can learn how optimize textures for 2D games.

Get introduced to Texture2D and learn how to work with raw images and manipulate pixel data at run time for 2D games. This course covers how to create texture renderings from scratch. Learn how to access pixel data, read color data, add pixels, and remove pixels. Discover how to further customize Texture2D files for use in a game.
