Generating Atlas Textures, And what does creating one achieve? To answer the first question, imagine this: you’ve created lots of different sprite images for your 2D game (all at different pixel dimensions)—one file for the player, one for each enemy, and one for each prop and power-up. That’s probably a lot of files! Then,

This included all filenames of textures inside the atlas, and their UV positions within the atlas. In closing that chapter, we tested the add-on functionality by assigning an Atla

However, because Unity is a 3D engine and our objects exist in three-dimensional space, we‘ll also need to convert screen space p

The preceding chapters focused on each of these issues in isolation, one at a time, and examined their implementation details and specifics. This chapter, and the one that follows, puts these ideas into practice in the form of a 2D game project. Spe

Of course, what‘s been presented in this book, however, should not be seen as the end of the line for 2D game development. It should be seen less as an ending point and more as a starting point. No book, no matter how larg
