Cut up spritesheets

- [Instructor] Now before we can start building our game…the last thing we need to go over is…how to cut up sprite sheets.…For now, we've been using individual sprites…and dragging them into the scene.…But a more efficient way of grouping sprites together…is to put them into a single texture.…Let's go into our jetroid artwork sprite sheet folder…and select the cave sprites.…It may be a little hard to see, but from the preview…they're actually multiple sprites inside…of this single texture.…

But by default, Unity doesn't know that.…We can go ahead and let Unity know that…this is actually a sprite sheet by changing…the sprite mode from single to multiple.…Now we need to cut up each of the sprites,…so let's go into the Sprite editor.…You'll also want to click Apply any time you make a change…to a texture, so let's go ahead and do that.…As you can see, we now have…the five tiles that'll make up our map.…You can actually drag and cut these out individually,…although this is a little bit time-consuming.…
