These files can also include other information about a sprite, if desired, such as a group they belong to, such as "Animation 1" or "Character XYZ". To handle the issue of designating which part of the spritesheet contains an individual sprite, spritesheets are usually accompanied by a file that tells where each sprite is located, including its width and height, and if the image is rotated, how much the image was rotated (90, 180, or 270 degrees). These sprite images are not all the same size, they have varying widths and, in practice, sprites can have varying heights within a sheet (some spritesheet makers will have an option to included rotated images to try to use up more of the padded space). Let's call it simple programmer art we made to test the spritesheet system because that is currently our goal. The result is you either pad an image with unneeded pixel information, wasting space, or you can place multiple sprites together in an image, filling the padded space, and creating a sheet of sprites, more commonly referred to as a spritesheet.įor this tutorial, let us say this is our spritesheet we wish to work with: There is a summary of the video content on the bottom of the same page if you scroll down below the comments.Įssentially, some graphics hardware require images to be of certain dimensions, and sprite images do not always match these dimensions. The spritesheet concepts apply to other languages and libraries.įor a nice summary of spritesheets and why they are useful, check out the video on this page that was kindly given to me for this article by Michael Tanczos: What is a sprite sheet?. Basic programming knowledge is assumed, however, knowledge of C++ and SFML is not required.

It's a good fit for larger projects and professional game development.This article aims to introduce spritesheets and how to incorporate them into your game. TexturePacker: TexturePacker is a more polished paid tool that supports advanced features and workflows. ShoeBox: ShoeBox is a free, Adobe AIR-based sprite packing utility that is great for small projects or learning how SpriteSheets work. You will need to use a 3rd party tool to assemble your sprite sheet files. Maximizing batching is a complex topic, but when multiple Sprites all share a common BaseTexture, it makes it more likely that they can be batched together and rendered in a single call. into a single draw call is the main secret to how PixiJS can run so blazingly fast. WebGL rendering speed scales roughly with the number of draw calls made.

Converting a project from individual source images to shared sprite sheets can cut your download time in half, at no cost in quality.

The number of files itself is a key driver of download speed, because each request requires a round-trip to the webserver, and browsers are limited to how many files they can download simultaneously. This means that the user's browser can request and download far fewer files for the same number of Sprites. While downloading a SpriteSheet's texture requires moving the same (or even slightly more!) number of bytes, they're grouped into a single file. SpriteSheets help your project in two ways.įirst, by speeding up the loading process.

Each texture uses the same shared BaseTexture as its source.

The SpriteSheet object then parses the JSON, and creates a series of Texture objects, one for each source image, setting the source rectangle for each based on the JSON data. These two files, in combination, can be passed into a SpriteSheet constructor. It then writes out a JSON file with that information. The sprite packer then collects the images, and creates a new combined image.Īs this image is being created, the tool building it keeps track of the location of the rectangle where each source image is stored. The first step is to collect the images you want to combine. The basic idea of a spritesheet is to pack a series of images together into a single image, track where each source image ends up, and use that combined image as a shared BaseTexture for the resulting Sprites. While somewhat more complex to create and use, they are a key tool in optimizing your project. Now that you understand basic sprites, it's time to talk about a better way to create them - the Spritesheet class.Ī Spritesheet is a media format for more efficiently downloading and rendering Sprites.
