Because Ankama still can't actually properly package for linux. (Ubuntu 18.04 Bionic tested)

dofus-setup-2.48.sh

#!/bin/bash

# This is a shitty workaround to Ankama not providing everything required in an actual package
# or even a proper dependency list.

# License: Unlicense, see bottom of file

if [ $# -ne 2 ]; then
  echo "Usage: $0 path/to/dofus.tar.gz path/to/place/game/folder"
  exit 0
fi

if [ ! -d $2 ]; then
  echo "Destination does not exist"
  echo "you can create it with:"
  echo "mkdir -p $2"
  exit 0
fi

#fix the fact that occasionally Ankama packs these without making certain files executable
#may remove this section in future versions, it has been nearly a year since the last time they messed this up.
if [ $EUID -ne 0 ]; then
   tar -xf $1 -C $2
   pushd $2 > /dev/null
   find . -print0 | xargs -0 -I '{}' file '{}' | grep "executable" | awk '{print $1}' | sed 's/.$//' | xargs chmod u+x
   echo "The script will relaunch and prompt for sudo to continue. it will take a lot of automated actions, so I hope you arent blindly trusting random code and read this. (5 seconds...)" 1>&2
   popd > /dev/null
   sleep 5
   sudo "$0" "$@"
   exit $?
fi

#sound dependency, After some testing, this one is no longer needed, removing from next version of script should this stay 
# apt install -y libasound2-plugins:i386

#outdated lib needed, but not packaged with (libpng12)
wget -q -O /tmp/libpng12.deb http://mirrors.kernel.org/ubuntu/pool/main/libp/libpng/libpng12-0_1.2.54-1ubuntu1_amd64.deb \
  && dpkg -i /tmp/libpng12.deb \
  && rm /tmp/libpng12.deb


#multiarch? hahaha
if ! dpkg --print-foreign-architectures | grep "i386"; then
   dpkg --add-architecture i386
fi


#wine dependency, but launching the game is a shell script :neutral-face:
#also, not just packaging a wine binary to keep from relying on system wine being a specific version...
wget -q -O https://dl.winehq.org/wine-builds/Release.key \
  && apt-key add Release.key
  && apt-add-repository https://dl.winehq.org/wine-builds/ubuntu/
  
apt update && apt install -y --install-recommends winehq-stable

# Other non-listed dependencies: 
# Accurate as of 2.47, fails on 2.48 without gtk2-engines-murrine:i386 or libcanberra-gtk-module:i386
# TODO: test which others are still needed, may still be all.
apt install -y \
  libxt6:i386 \
  libgtk2.0-0:i386 \
  libstdc++6:i386 \
  libxml2:i386 \
  libxslt1.1:i386 \

echo "You should be ready to run now."

Thanks for libpng12 trick :)

Any clue on how to implement something similar in arch?
