**Application Layer** (hardware \u0026 os - mainly platform-dependent things and core)\n  - **Game Logic Layer** (game logic)\n  - **Game View Layer** (game presentation - renderer \u0026 sound, also networking belongs to game view)\n      * **Network Layer**\n  - **Main** \u0026 **Desktop** (application startup)\n  \nAll this maven modules are dependencies from **main module** which are called from desktop module.\n  \nAdditional modules:\n\n  - Shared Commons Library (shared with proxy \u0026 gameserver, includes network protocol)\n  - desktop (contains natives for different platforms, belongs indirect to application layer)\n  \n## Game Directories\n\n  - data (all game specific data)\n  - temp (temporary files, write access required)\n  - docs (Documentation, will not be copied into zip archiv)\n  - assets (Work in Progress directory for artists, will not be copied into zip archiv)\n  - config (configuration files for game engine - but no game specific configuration files!)\n  \n## Flow Chart\n\n![Flowchart](./docs/Flowchart.png)\n  \n## Deploy shared-commons-library\n\n```bash\nmvn clean install deploy -DuniqueVersion=false\n```\n\n**Important**! If anything in shared-commons-library was changed, you have to increment version, else proxy server maybe doesn't get the right snapshot.\n  \n## Rebuild texture atlases\n\n**Important**! Textures which will be packed to texture atlases with data/misc/packer/packer.json config file will be cached in temp directory.\\\nTo rebuild them, you have to clear the cache with this optional parameter:\n\n```text\n-DclearCache=\"true\"\n```\n  \n## Build ZIP archiv\n\nMaven:\n```bash\nmvn clean install\n```\n\nThen you can find a ZIP Archiv in directory **desktop/target** with all files required for game.\n\n## Z-Level\n\nFinally a little not about the **z-level**. By default, 2D games have only two axes: x and y.\\\nBut maybe you also want to support a \"render order\" or even floors and underground tunnels.\\\nThen you need a **render order** and a specific system of layers to hide or show.\\\nI have introduced a z-level system as follows:\\\n\\\n**Every** tmx layer requires a **z-level**. Else the client cannot load them.\\\nAdditionally, you have to make the render order in tiled, so it's already right in tmx format.\\\nNext all your layers get a z-level like this: **floor.renderOrder**\\\nThe player is rendered on z-level **1.5** by default.\\\n\\\nFor **example**:\\\nz-level \"1.0\" is the **ground floor** and \"2.0\" is the second floor.\\\nIf you want to introduce a layer with street lights whose lamps should hanging over the player, you need a z-level \"1.6\".\\\nBut **attention**! If the player is in second floor, the lamp will not be rendered!\n\n## License\n\nThe source code is licensed under **Apache 2.0 license**.\\\nBut **assets in directory data/ can be licensed under different licenses**!
