Hi TajRizek,
Minifantasy is a modular collection. All the animations where the base characters (the "naked" humanoids included in this pack) use different tools or weapons are presented in separate layers to permit users an easy customization. By providing characters and tools separately, Minifantasy users can create their own custom characters (using the base humanoids as base) or change the shape of the tools or weapons to make their own versions.
As for the shadows, they come in a separate layer because some devs prefer to create their own shadows using different "in-engine" techniques instead of using the shadow sprites. Providing shadows separately offers more versatility for using the assets.
To build up the animations you have two options:
- Render the layers in your game engine in this order:
- Shadow (if you decide to use them)
- Toolback
- Character
- Toolfront
or
- Put the layers together in Aseprite, GIMP or Photoshop and export the image as a single .png and use it as a single layer in your engine (.aseprite files are included in the asset pack from where you can export the different characters using the tools).
