Applies to: Adobe Animate. Create a sprite sheet or texture atlas and export your animations for mobile apps and game engines. Import a texture atlas to Unity or any of your favorite game engines by using the plug-in.

Sprite Sheet A sprite sheet is a bitmap image file that contains several smaller graphics in a tiled grid arrangement. A sprite sheet containing the sprites in a frame-by-frame animation. Texture atlas Texture atlas is a collection of textures as a single large image or multiple images of the desired dimension.

Difference between a sprite sheet and texture atlas You can use either sprite sheet or texture atlas in your mobile apps as per your requirement. Number of bitmaps generated Based on number of frames used in sprite sheet, number of bitmap files can also increase resulting in the increase of sprite sheet size Only unique bitmaps are generated in sprite, thus reducing the total size.

Creating a sprite sheet. To create a sprite sheet, perform the following steps:. Right-click the selection and choose Generate Sprite Sheet. Export option Description Image dimension The total size in pixels of the sprite sheet. The default setting is Autosize, which sizes the sheet to fit all the sprites you include. Image format The file format of the exported sprite sheet. Border Padding Padding around the edges of the sprite sheet, in pixels.

Shape Padding Padding between each image within the sprite sheet, in pixels. Algorithm The technique used for packing the images into the sprite sheet.

Choose the format that best suits your intended workflow for the sprite sheet after export. This option is only available for some data formats. Trim This option saves space on the sprite sheet by trimming unused pixels from each symbol frame added to the sheet.

Stack Frames Selecting this option prevents duplicate frames within the selected symbols from being duplicated in the resulting sprite sheet. Export animations to mobile apps or gaming engines. In the Library , right click the movie clip. Select Generate Sprite Sheet. In the Sprite Sheet dialog box, select the required options. Click Export. How to export animations for mobile apps or gaming engines. Creating a texture atlas.

An illustration depicting the workflow for generating texture atlas and importing it into Unity. To generate texture atlas of your animation, perform the following steps:. Generate texture atlas. Choose the appropriate export options for texture atlas. Export option Description Image dimension The total size in pixels of the texture atlas. The default setting is Autosize, which sizes the sheet to fit all the images you include. Optimize dimensions When Optimize dimensions option is checked, it removes empty pixels from bitmaps and dimensions are not in power of two default option.

This is applicable for all the bitmaps generated. When Optimize dimensions option is unchecked, bitmaps are generated based on the selected dimensions.

Resolution Choose any value ranging from 0. Algorithm The technique used for packing the images into the texture atlas. The default is the JSON format. Flatten skewed objects to bitmap Select this option if you are using skewed transforms for your objects. Animate converts these objects into bitmap images as some of the game engines do not interpret skew transforms appropriately.

Optimize Animation. When Optimize animation. You can choose to export the symbol into multiple bitmaps based on the dimension. Generate texture atlas for multiple bitmaps. To preview the texture atlas output, click Preview tab. Preview the texture atlas after creating it. Finally, change the Duration value in the Animation patch to 0. The final step is to make the audio play when the interaction is detected.

So that the sound is triggered by the same signal that triggers the particles, connect this patch to the Turned On output of the Pulse patch. Use the Patch Editor to make an object move with the user like a puppet and add procedural animation.

At the moment the particles look like 2 streams of squares covering the scene: The sprite sheets will make each particle look like a piece of confetti, spinning as it falls.

To import the sprite sheets: Click Add Asset in the Assets panel. Select the sprite sheets from the sample content folder. Click Import From Computer Create the material To create a material for the particles: Select both particle systems in the Scene panel. You can select them at the same time by holding down command on your keyboard - or control on Windows machines. Set the Shader Type in the material to Flat.

Create an animation sequence To add an animation sequence to your project: Click Add Asset. Select Animation Sequence. You can do things like: Start the animations at random times after the effect has opened - by checking the box next to Randomize.

Make the animation play once, instead of looping continuously - by unchecking the box next to Loop. Add the sprite sheet to the animation sequence To do this: Select animationSequence0 in the Assets panel. Next to Diffuse , click the dropdown and select animationSequence0. In the Inspector: Each box should be checked next to Loop and Randomize. Creating a Sprite from a Sprite Sheet A sprite sheet is a way to combine sprites into a single file.

The SpriteFrame is loaded once and retained in the SpriteFrameCache Here is an example sprite sheet: It doesn't look like much but let's take a closer look at what is happening: As you can see the sprite sheet , at a minimum it reduces unneeded space and consolidates all sprites into a single file.

Let's tie this all together! Tools for creating Sprite Sheets Creating a sprite sheet manually is a tedious process. No results matching " ".
