Installation

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.

Usage

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

Sprite sheet data file

_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.
