Exploring Texture Packer

Texture Packer is a very popular piece of software that is used by industry professionals such as Disney, Zynga, and WG Games to create sprite sheets. You can download it from https://www.codeandweb.com/.

This is similar to how we created the images earlier when creating enemy animations. To create sprite sheet animation using Texture Packer, you also have to create the individual frames in Photoshop or Illustrator first. I have already made them and have each of the images for the individual frames ready.

You can use the trial version of Texture Packer to follow along the tutorial. When downloading, choose the version that is suitable for your operating system. Fortunately, Texture Packer is available for all major operating systems, including Linux.
