Flash Sprite Sheet Importer

A Unity plugin to help import Sprite Sheets generated from Adobe Animate (Flash)

Version 1.2.0 can be installed from this GitHub Link

Older version available on the Unity Asset Store

Getting Started

Adobe Animate Instructions

• Each sprite sheet can contain one or more movieclips.
• Export sprite sheets with their corresponding XML files (describing the location of all sprites).
• The Starling XML format now adds the possibility to use pivots from original movieclips.

Unity Instructions

• Get importer window by opening: Window -> Sprite Sheet Importer
• Then select a 2D Texture sprite sheet (alongside accompanying XML file).
• The Force Overwrite Pivot checkbox:
  • Shows a pull down menu to manually select a pivot position.
  • Can be used to ignore existing pivot data from the XML file.
  • Avoid using this option if the pivot point from Animate is already correct!
• The Generate Animation checkbox:
  • Creates an Animator for the sprite sheet.
  • Also creates Animations for each animation movieclip.
  • Shows a field to choose frames per second for those Animations.
  • Shows a Generate GameObject checkbox which can be used to create a GameObject with the Animator.
  • Warning: This function can overwrite previously generated elements without notice.
• Finally, press 'Import Sprites'.
