SpriteSheet Detection package
It is not uncommon for games to have tens to hundreds of sprites. Loading each of these as an individual image would consume a lot of memory and processing power. To help manage sprites and avoid using so many images, many games use sprite sheets (also known as image sprites).
A sprite sheet consists of multiple sprites in one image. In other words, sprite sheets pack multiple sprites into a single picture. Using sprite sheet, video game developers create sprite sheet animation representing one or several animation sequences while only loading a single file:
Sprite Bounding Box
A frame (bounding box) can be used to delimit the sprite in the sprite sheet. This bounding box is defined with two 2D points
top_left and the
bottom_right, which their respective coordinates
y are relative to the top-left corner of the sprite sheet's image.
What the project does
- Detect sprites packed in an image (sheet) and draw their masks and bounding boxes into a new image with the same size of the original image.
- Present a 2D map of all the the sprites with their labels.
- Python 3.7 is required.
- Use git to clone the link
https://github.com/intek-training-jsc/sprite-sheet-hoaithu1.gitto your local directory.
- Change the your current working directory to where you git the project.
- Open terminal and type
pipenv install -e Pipfileto install virtual environment.
- For example:
>>> from spritesheet_detect.spriteutil import SpriteSheet >>> sprite_sheet = SpriteSheet('Barbarian.gif') >>> sprites, labels = sprite_sheet.find_sprites() >>> len(sprites) 39 >>> # Create the mask image with bounding boxes. >>> image = sprite_sheet.create_sprite_labels_image() >>> image.save('barbarian_bounding_boxes.png')
