LogicAtlas-CLI.exe [Flags]

-o Output filename (default: atlas)

--padding Pixel padding between sprites (default: 2)

C : Center (0.5, 0.5)

TL: Top-Left (0.0, 0.0)

BC: Bottom-Center (0.5, 1.0) - Great for characters

To pack a folder of RPG characters with Bottom-Center pivots (for feet alignment): code Bash

LogicAtlas-CLI.exe "./Sprites/Characters" -o Chars --pivot BC

The tool outputs a standard JSON. Parse it to set up your sprites automatically. code Gdscript

var data = JSON.parse_string(json_text) $Sprite2D.region_rect = Rect2(data.x, data.y, data.w, data.h) $Sprite2D.offset = Vector2(data.w * data.pivot_x, data.h * data.pivot_y)
