Un projet pour tester et apprivoiser godot. Ce n'est pas un client officiel. Utile également pour se balader dans les décors et voir les objets nouvellement créés dans un client godot.

Build

Before build and launch client, build module (before, we need include modules on godot source)

Build module

mkdir build
cd build
# Disable build directory on godot editor
touch .gdignore
# clone godot
git clone https://github.com/godotengine/godot.git
cd godot
# switch on release
#git checkout 3.1.2-stable
git checkout 3.2
# Create link with our module (or copy file to godot/modules - as you like)
cd modules
for file in ../../../modules/*
do
   if [ -d $file ]
   then
      if [ -L $file ]
      then
         echo "Create link $(basename $file)"
         ln -s $file .
      else
         echo "Link $(basename $file) exist"
      fi
   fi
done
cd ..
# Copy modules doc to godot
cp modules/*/doc_classes/* doc/classes/.
# Clean project (if you build before)
scons -j$(nproc) -c
# Build a debug version
scons -j$(nproc) platform=x11 target=debug
# or build release_debug
scons -j$(nproc) platform=x11 target=release_debug
# or build release -> becarefull, this version works on root project and impossible to launch editor
scons -j$(nproc) platform=x11 target=release tools=no

# Build optimized with GCC
scons -j$(nproc) platform=x11 target=release_debug use_lto=yes
# Build optimized with CLang
scons -j$(nproc) platform=x11 target=release_debug use_llvm=yes use_lld=yes
cd ../..

Generate doc

If you want, you can regenerate doc. (Normally it's generated)

cd build/godot
./bin/godot.x11.tools.64 --doctool .
cp modules/*/doc_classes/* doc/classes/.

Launch godot with module

cd build/godot
bin/godot.x11.tools.64
cd ../..

Package client khaganat

Configure export

Configure on project export (or edit file export_presets.cfg)

Ex.: export_presets.cfg

[preset.0]

name="khaganat.linux.64"
platform="Linux/X11"
runnable=true
custom_features=""
export_filter="all_resources"
include_filter=""
exclude_filter=""
export_path=""
patch_list=PoolStringArray(  )
script_export_mode=1
script_encryption_key=""

[preset.0.options]

texture_format/bptc=false
texture_format/s3tc=true
texture_format/etc=false
texture_format/etc2=false
texture_format/no_bptc_fallbacks=true
binary_format/64_bits=true
custom_template/release=""
custom_template/debug=""

Generate package

godot --path . --export khaganat.linux.64 khaganat.linux64.bin

Launch client khaganat

With godot

godot login_scene/login_scene.tsc

Library

NetworkConnection

NetworkConnection -> class to manage/use NetworkConnectionCore All times, connect on NetworkConnectionCore (to get singleton) and launch function The goal is to don't managed Singleton, this class manage At end of program, you need execute function "terminate_network_connection" to remove singleton.

NetworkConnectionCore -> class Singleton (uniq object) [contains network connexion, state connexion] _state_connexion[StateConnectionBase] : Object change class with state connexion [StateConnectionNotInitialized, StateConnectionLogin, StateConnectionSynchronize, StateConnectionConnected, StateConnectionQuit] _network_data [NetworkData] : Object state connexion (Tick receive, send, bit acknowledge) _queue [BitStreamQueue] : queue to store message UDP (just simple method to try re-order message receive by UDP) _socketUDP [Ref] : network connexion

  NetworkConnection(object A)             NetworkConnection(object B)     ...
         |                                       |

+-------+----+---------------------------------------+-----------------------------------------+ | NetworkConnectionCore * _network_data * _queue * _socketUDP * _state_connexion if StateConnectionConnected

ReferentialMessage

ReferentialMessage -> class to manage/use ReferentialMessageCore

ReferentialMessageCore -> class singleton (uniq object) [Manage data provide by msg.xml], we can encode/decode khaganat's message
