Sprite atlas

In computer graphicsa texture atlas also called a spritesheet or an image sprite in 2d game development is an image containing multiple smaller images, usually packed together to reduce overall dimensions. In an application where many small textures are used frequently, sprite atlas, it is often more efficient to store the textures in a texture atlas which is treated as a single unit by the graphics hardware, sprite atlas. Careful alignment may be needed to sprite atlas bleeding between sub textures when used with mipmapping and texture compression. In web developmentimages are packed into a sprite sheet to reduce the number of image resources that need to be fetched sprite atlas order to display a page.

Imagine you have a game in Unity where you use thousands of materials all across the project, whether for characters, NPCs, environments, UI, or anything else. In such cases, generating a lot of textures or meshes — or applying materials with multiple shaders — might increase something called "Draw Calls" in your game. A Draw Call is a call to the graphics API to draw an object — like a mesh — and draw call batches are the calls done to the graphics API in bulk to draw objects together. Having too many batches of draw calls in your game might slow down your game. Even worse, it might significantly affect your FPS and make your game unplayable if it isn't managed well.

Implemented in: UnityEngine. Thank you for helping us improve the quality of Unity Documentation. Although we cannot accept all submissions, we do read each suggested change from our users and will make updates where applicable. For some reason your suggested change could not be submitted. And thank you for taking the time to help us improve the quality of Unity Documentation. Sprite Atlas is an asset created within Unity. It is part of the built-in sprite packing solution. A Sprite Atlas stores a list of packable assets. Sprite or Folder. Before the packing process begins, these packable assets will be grouped and traversed to gather all the sprites from them. These will be used in the packing process.

And thank you for taking the time to help us improve the quality of Unity Documentation, sprite atlas. Having too many sprite atlas of draw calls in your game might slow down your game. To have a basic idea of what draw calls do, I have created a simple Unity scene with multiple UI images around them.

Unity creates the Sprite Atlas in the Assets folder, with the file extension. Version: Language : English. Unity Manual. Unity User Manual Sprite Atlas.

A 2D project uses sprites A 2D graphic objects. If you are used to working in 3D, Sprites are essentially just standard textures but there are special techniques for combining and managing sprite textures for efficiency and convenience during development. More info See in Glossary and other graphics to create the visuals of its scenes A Scene contains the environments and menus of your game. Think of each unique Scene file as a unique level. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. More info See in Glossary. This means a single project can contain many texture files.

Sprite Atlas is created via the menu option in the Editor and will stay as an asset Any media or data that can be used in your game or Project. An asset may come from a file created outside of Unity, such as a 3D model, an audio file or an image. Sprite Atlas asset provides a set of texture settings for the packed texture. Regardless what was the texture settings of the sprite A 2D graphic objects. If you are used to working in 3D, Sprites are essentially just standard textures but there are special techniques for combining and managing sprite textures for efficiency and convenience during development. More info See in Glossary being pack in an atlas, the result atlas texture will only respect the settings in the atlas asset. User will be able to create another Sprite Atlas A texture that is composed of several smaller textures. Also referred as a texture atlas, image sprite, sprite sheet or packed texture. Sprite Atlas See in Glossary asset and declared it is a variant of one existing Sprite Atlas in the project. You can change the sprite packing mode from Disabled to either:.

More info See in Glossary. Even worse, it might significantly affect your FPS and make your game unplayable if it isn't managed well. When the Editor is in Edit mode, sprites continue to use their original textures and not textures from a packed Sprite Atlas. A reference to a Sprite Atlas can be added later. The original version 1 of the Sprite A 2D graphic objects. Language English. DestroyImmediate Destroys the object obj immediately. This maximizes the density of Sprites in the combined Texture, and is enabled by default. If you select Sprite Atlas V2 - Enabled for Builds , Unity only packs Sprite Atlases when building Players, AssetBundles, or Addressable build scripts A piece of code that allows you to create your own Components, trigger game events, modify Component properties over time and respond to user input in any way you like. A Sprite can be loaded without referencing any Sprite Atlas. Suggest a change. Hidden categories: Articles with short description Short description matches Wikidata. Sprite atlas also packs them into a single power-of-4 image, which lets you compress the image simultaneously.

This property is disabled by default. Language English. ToString Returns the name of the object. You can either pack the whole folder into a sprite atlas or add single images to the list by adding them individually. This doubles the amount of memory required for Texture Assets, and can negatively affect performance. Disable this option if the Sprite Atlas contains Canvas UI element Textures, as when Unity rotates the Textures in the Sprite Atlas during packing, it rotates their orientation in the Scene A Scene contains the environments and menus of your game. Language : English. Check this box to allow the Sprites to rotate when Unity packs them into the Sprite Atlas. Unity creates the Sprite Atlas in the Assets folder, with the file extension. If you enable this property, Unity creates a copy of the Texture data.
