Added a Unity-specific check to the Spritesheet generator that will not allow you to generate spritesheets larger than 16384 in a single dimension, the limit for textures in Unity.
Original Repo Description from Bogdan Rybak
Spritesheet generator is for those who work with Photoshop's animation functions and want to easily export their animations into a simple spritesheet.

- @SebaschenLiu - thanks for the awesome padding feature and UI enhancements <3
Download the raw version of the script
Place Spritesheet generator.jsx script into:
- Windows - C:\Program Files\Adobe\Your photoshop version\Presets\Scripts
- Mac - Applications > Your photoshop version > Presets > Scripts
Restart Photoshop if it was open.
The script will now be available under File -> Scripts menu as "Spritesheet Generator".
You can specify the frame range. The columns and rows will be automaticaly calculated - you can change them to suit your needs.
You also have the option to add padding in between frames to avoid bleeding.
Export options:
- Save as PNG - generates and then saves a PNG24 of the generated sprite sheet along with a _spritesheets.txt file in the same folder
- Generate document - generate your spritesheet into a new photoshop document with "Document Name" field and cell size as the name i.e. basic_attack_32x32
_spritesheets.txt will be created / updated everytime you use Save as PNG option and will store sprite sheet information for all generated pngs in the folder it resides. Extra options:
- Check "Separate Padding Data" to extract more detailed spritesheet information with padding information on each side (by default) The generated _spritesheets.txt format is:
Without Separate Padding Data (default):
spritename,cell width + padding left + padding right,cell height + padding top + padding bottom,number of frames
for example,
basic_attack.png,68,68,4
basic_attack_1.png,36,36,4
DustAnimationExample.png,22,10,4
With Separate Padding Data:
spritename,cell width,cell height,padding left,padding top,padding right, padding bottom,number of frames
for example,
basic_attack.png,64,64,2,2,2,2,4
basic_attack_1.png,32,32,2,2,2,2,4
DustAnimationExample.png,18,6,2,2,2,2,4
each entry uses a new line
This file exists so that you can setup whatever workflow within your game engine or other tools to read and slice your spritesheets.
