In newer versions of Unity, the Sprite Editor isn’t installed by default it’s moved into the package system and needs to be added. In the Inspector, the Sprite Mode is already set to Multiple (if not, change it, then click Apply). Both of these animations consist of multiple frames, which you can edit and slice using the Sprite Editor.Īssets/Sprites/Explosion/explosion-spritesheet.png has already been sliced and prepared into an animation for you, but Assets/Sprites/thruster-spritesheet.png still needs some attention.Ĭlick Assets/Sprites/thruster-spritesheet.png in the Project window. You’ll use two spritesheets in this game: one for the lander’s thruster animation, and one for an explosion animation. It’s convenient to pack multiple graphic elements into a single image for animations or objects that have lots of moving parts Unity makes it easy to manage these spritesheets with a built-in 2D spritesheet editor.

Of course, organization of your spritesheets is just as important as using them, but that’s for another tutorial! Sprite Editing

For a few dozen sprites, this isn’t a big deal, but as your game grows in complexity and scope, this could be a potential issue.īy using spritesheets, you’re making one draw call for lots of Sprites, thus giving your game a performance boost. The reason for using spritesheets is that every image you use in your game will take up one draw call. Examples: triangle, square, pentagon, hexagon.Ī spritesheet is a single image that contains lots of smaller individual images, like so:

Polygon: A custom polygon-shaped sprite that you can create many different types of primitive shapes with.

Multiple: A sprite with multiple elements, such as animations, or spritesheets with different parts for a character.

In the Inspector, there are three different modes in which you can use sprites: Sprite ModesĬlick a sprite in the Assets / Sprites folder. Now, delete the playership GameObject from the Hierarchy. That’s all it takes! The Sprite Renderer lets you display images as Sprites in both 2D and 3D scenes. Notice that Unity automatically attached a Sprite Renderer component, which contains your playership sprite, to the GameObject: In the Hierarchy, click the playership GameObject Unity created for you and look at its details in the Inspector. Then, drag the playership sprite from the Sprites folder into your Scene view: To see for yourself how easy the process is, first select the Scene view. To add a sprite to your game, drag and drop it from your Project folder into your Scene view. In a nutshell, Sprites are easy to work with in Unity, thanks to a great 2D workflow and built-in editor. However, Unity has special techniques for combining and managing these sprite textures to get super efficient performance in your games, as well as a convenient development experience. They are essentially standard textures you would usually use for 3D objects. This option has already been set in the starter project for you.Īt a high level, Sprites are simply just 2D Graphic objects. You can choose 2D or 3D mode when you create a project from scratch.

Note: 2D games in Unity - quite logically - use the 2D mode of the Unity Editor.
