# Stage the JRPG tutorial's own assets in the sandbox.

# Same job as sidescroller.sh, and the same reason: docs/21-tutorial-jrpg.md
# shows the reader real sprite and character files out of
# docs/tutorials/assets/jrpg, and a beginner following the chapter types what is
# on the page -- so what is on the page has to be a file that loads.
#
# Two directories are staged, because the checker looks in two places:
#
#   ./                a `json kind=sprite` block's spritesheet path is resolved
#                     relative to the sprite file, which lives in the sandbox root
#   ./sprites         tools/docs_checkjson.c loads everything here through
#                     akgl_sprite_load_json before it touches a `kind=character`
#                     block, since a character resolves its sprites by name
#
# $1 is the repository root. The caller runs this with the sandbox as the
# working directory.
