# Builds the runtime resource pack PixelPics renders from (blockstates, models, textures, items,
|
|
# atlases, font) straight from Mojang's CLIENT jar — no launcher install needed. The plugin ships no
|
|
# assets itself; drop the resulting zip into plugins/PixelPics/resourcepack/. Run it once per
|
|
# Minecraft update. No pack.mcmeta needed (the client jar has none; the loader detects a zip by its
|
|
# vanilla blockstate files).
|
|
#
|
|
# Needs: curl, jq, unzip, zip.
|
|

# Usage: tools/build-vanilla-pack.sh 26.3 # -> ./vanilla-26.3.zip
|
|
# tools/build-vanilla-pack.sh 26.3 <output-dir> # -> <output-dir>/vanilla-26.3.zip
