Simple atlas file generator for libGDX

This python script generates atlas files for libGDX TextureAtlas class. You can use it with existing sprite sheets downloaded from sites like OpenGameArt.org.

Usage

python ./libgdx-sprite-sheet-to-atlas.py sprite-sheet-filename sprite-sheet-width-px sprite-sheet-height-px tile-width-px tile-height-px [tile-count-limit]

• sprite-sheet-filename - sprite sheet texture filename
• sprite-sheet-width-px - width of sprite sheet texture in pixels
• sprite-sheet-height-px - height of sprite sheet texture in pixels
• tile-width-px - width of single tile/sprite in pixels
• tile-height-px - height of single tile/sprite in pixels
• tile-count-limit - limit of generated tiles (optional)

Example

python ./libgdx-sprite-sheet-to-atlas.py mytiles.png 256 128 128 64

Generated mytiles.atlas:

mytiles.png
size: 256,128
format: RGBA8888
filter: Linear,Linear
repeat: none
mytiles_00000
  rotate: false
  xy: 0, 0
  size: 128, 64
  orig: 128, 64
  offset: 0, 0

Every tile in sprite sheet must have the same width and height.

Tiles are in horizontal order, without any gaps between.

Script doesn't check if passed arguments have any sense.
