Use when a 2D character needs cosmetic atlas-slot, skeletal-skin, or palette swaps while gameplay collision, timing, and stats must remain unchanged.

The file

We split this skill into the rules it gives an agent

2 rules. About 0 are common, 1 is distinctive, and 1 is very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈1

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 1

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Very specific:

    Use with spine-skeletal. Do not load a missing spine-2d path.

    line 16
  2. Distinctive:

    After swap, re-check socket names (weapon, hand) against model-pipeline / character-rig contracts.

    line 23

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Sprite skin

Ask the column:

ColumnWhat swaps
atlas-slotone region in a sprite sheet
spine-skinSpine skin / slot attachment
palette-swapcolors only

Use with spine-skeletal. Do not load a missing spine-2d path.

Rules

  1. Skin is paint. Hitbox/hurtbox geometry is owned by hitbox-hurtbox; collision filters/layers are owned by collision-layers.
  2. A paid skin is cosmetic. See game-monetization. No paid i-frames.
  3. Atlas pack by draw order. Missing attachment falls back to a published default, not a crash.
  4. After swap, re-check socket names (weapon, hand) against model-pipeline / character-rig contracts.
  5. Pixel-animation sheets use atlas-slot, not a second skeleton.

Accept

Swap skin in the pause menu: same hitbox, same cancel window. A missing slot shows the default arm, not a hole in the hurtbox.
