Anaïs Saraiva 4c7da4cab5 nosingleplayer 1.1.9 : menu titre résilient (repli vanilla) + launcher : plus de console noire Windows
Écran noir au menu titre sur les PC Windows (2 postes) : dans
TitleScreen.extractRenderState, les widgets sont dessinés juste APRÈS
extractPanorama. Toute exception dans la redirection du panorama
interrompt donc le rendu du menu entier (écran noir, sans bouton).

Mod nosingleplayer 1.1.9 :
- try/catch autour du fond custom + repli automatique sur le panorama
  vanilla (avant : écran noir définitif si la texture est refusée par
  le GPU ou absente du jar) ;
- try/catch autour de la construction du menu, et les widgets vanilla ne
  sont retirés qu'APRÈS la création des widgets SurviePote (avant : une
  exception laissait un menu vidé) ;
- ping serveur déplacé sur un thread dédié : il était lancé depuis
  extractWidgetRenderState, donc sur le thread de rendu (un DNS lent
  suffisait à figer le menu) ;
- log GPU au démarrage du menu (nom/vendor/pilote/backend) ;
- option de diagnostic -Dsurviepote.customTitle=false (menu vanilla).

Launcher : java.exe est lancé avec detached:true sans windowsHide ->
sur Windows, une console noire et vide s'ouvre par-dessus le jeu.
Ajout de windowsHide:true.

atlas : distribution.json regénéré (MD5/URL du nouveau jar).

Development

This section details the setup of a basic developmentment environment.

Getting Started

System Requirements


Clone and Install Dependencies

> git clone https://github.com/dscalzi/HeliosLauncher.git
> cd HeliosLauncher
> npm install

Launch Application

> npm start

Build Installers

To build for your current platform.

> npm run dist

Build for a specific platform.

Platform Command
Windows x64 npm run dist:win
macOS npm run dist:mac
Linux x64 npm run dist:linux

Builds for macOS may not work on Windows/Linux and vice-versa.


Visual Studio Code

All development of the launcher should be done using Visual Studio Code.

Paste the following into .vscode/launch.json

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Debug Main Process",
      "type": "node",
      "request": "launch",
      "cwd": "${workspaceFolder}",
      "program": "${workspaceFolder}/node_modules/electron/cli.js",
      "args" : ["."],
      "outputCapture": "std"
    },
    {
      "name": "Debug Renderer Process",
      "type": "chrome",
      "request": "launch",
      "runtimeExecutable": "${workspaceFolder}/node_modules/.bin/electron",
      "windows": {
        "runtimeExecutable": "${workspaceFolder}/node_modules/.bin/electron.cmd"
      },
      "runtimeArgs": [
        "${workspaceFolder}/.",
        "--remote-debugging-port=9222"
      ],
      "webRoot": "${workspaceFolder}"
    }
  ]
}

This adds two debug configurations.

Debug Main Process

This allows you to debug Electron's main process. You can debug scripts in the renderer process by opening the DevTools Window.

Debug Renderer Process

This allows you to debug Electron's renderer process. This requires you to install the Debugger for Chrome extension.

Note that you cannot open the DevTools window while using this debug configuration. Chromium only allows one debugger, opening another will crash the program.
