# This compiles the Luanti client with SDL2 support to run as native Wayland
# client. Change to 0 if you encounter any issues. When set to 0, the client
# runs without SDL2 support as an Xwayland client.
#
# You can also set this to 0 if you’re not using Wayland, without any real
# effect on how the Luanti client runs.
_use_sdl2=1


# The upstream archive ships the devtest game. To keep a small installation
# footprint, this PKGBUILD removes this game by default. Set this variable
# to 1 if you want to keep devtest.
#
# Devtest can be installed via CDB:
#  → https://content.luanti.org/packages/Luanti/devtest/
_install_devtest=0


# The additional files are individually loaded from my webserver. If you
# want to redistribute this PKGBUILD, just set another location.
#
# If you store the files alongside this PKGBUILD file, use '.' here.
