# This tool launches battle.net, waits for it to be ready, then launches your
# game via the launcher for easy steam integration.
#
# Inspired from bnetlauncher, which only works on Windows due to a dependency on WMI:
# https://github.com/dafzor/bnetlauncher
# 
# To use, please set the variables in the "Configuration" section - mainly, you
# need to set LUTRIS_BNET_IDENTIFIER to the "Identifier" for the Battle.net
# launcher in Lutris and LUTRIS_GAME_IDENTIFIER to the "Identifier" for the
# game EXE in Lutris. To find this value, open Lutris and right click your
# Battle.net launcher and click "configure" - there should be an "Identifier"
# value that is greyed out- do the same for your game exe.

# Configuration:
USE_LUTRIS=1 # set to 0 if you don't want lutris - you will need to set BIN below to your custom binary
LUTRIS_BIN="flatpak run net.lutris.Lutris"  # the system binary for lutris (default assumes flatpak install)
LUTRIS_BNET_IDENTIFIER="battlenet" # the "Identifier" for Battle.net launcher 
LUTRIS_GAME_IDENTIFIER="${1:-d2r}" # the "Identifier" for the game you want to run, default allows passing via CLI argument
GAME_EXE="D2R.exe" # wait until this game is exited
WAIT_GAME=1 # set to 0 to disable waiting for game
WAIT_TIMEOUT=60 # timeout to wait for game launch
KILL_LUTRIS=1 # set to 0 to keep Lutris & Battle.net open

echo "Playing $LUTRIS_GAME_IDENTIFIER"

# first, we run lutris & battle.net in the background
$LUTRIS_BIN lutris:rungame/$LUTRIS_BNET_IDENTIFIER &

# now, we wait for MAX_HELPER_COUNT to indicate battle.net is running
# I chose the value for MAX_HELPER_COUNT based on trial and error - you may
# have to increase or decrease the value if battle.net changes
MAX_HELPER_COUNT=3
HELPER_COUNT=0
while [ $HELPER_COUNT -lt $MAX_HELPER_COUNT ]; do
