Asset Manager

Project meant to make common tasks around assets easier to do. Exposes a cli currently to interact.

Current Commands

1. pack
   • Pack a directory of images to one spritesheet
   • generate a ron file detailing sprite locations
   • Uses sheep packager
2. strip
   • Iterates over images and outputs a separate directory of images without extra transparency.
   • Determines the perfect bounding box which still contains all non-zero alpha pixel values

assetmanager's Issues

Pack should show a progress bar

Packing can take a while.
look into some kind of progress bar for each step:

• loading images
• writing to file

Strip transparency from image

• Have a way to tell the program where images are located

• bottom / center etc

• Specify a common bounding box

• Load Image by most common medium length

• If there is no transparency in boundaries, go up a bounding box

• If there is transparency, calculate new bounding box, crop and save

Nice to have:

• Read in first 5/10 images and output common bounding boxes

Sheep may be packing images incorrectly

Its also not respecting max_width / max_height

Investigate pack outputting multiple sprite sheets

look into outputting multiple spritesheets so they can be power of 2 and not exceed max texture sizes.

Separate into cli and lib?

Separating into a cli and lib could make it easier for people to import certain functions and use them.
e.g.
A particle editor could load in a texture and show what it looks like with normal map?

Create script or some command to chain pipeline commands

Would be useful to take in an art directory and pass it through a pipeline of steps

1. strip
2. pack
   ...
   Future ideas
3. Generate normal maps

Pack images with tags

Add tags to amethyst format, like file name so you can query images in a SpriteSheet without knowing index

Pack should take in a directory

Strip transparency from a list of files or directory

Strip should read from a custom directory
Mainly so a user can have a separate art directory and those files will stay unaltered.

Investigate normal map generation
