Cytopia is a free, open source retro pixel-art city building game with a big focus on mods.

This PR removes the duplicate cmake code that was used to find the dependencies, now all the dependencies are defined in cmake/DependenciesConfig.cmake instead of the main CMakeLists.txt

Features:

• Unified the dependencies in one file, this makes it easier to see what versions are being used
• Replaced vcpkg with conan
• On-demand fallback on conan ¹
• Removed the pmm cmake-module

Fixes #785 Fixes #770 Fixes #834 Fixes #839

¹ Setting the cmake option CYTOPIA_LIB_PREFERENCE to SYSTEM will search the system first for dependencies, and then fall back on the Conan package if it hasn't been found

I've moved the cmake / cpack specific files to a seperate folder and i've included the CompileOptions.cmake.

Both windows and linux now use increased warning levels and treat warnings as errors.

All warnings that occured with the increased warning levels are fixed in this branch.

Writing to the current working dir can cause write access problems. Also, when Cytopia is update, existing settings and save games would be overwritten. Writing to another directory would help to sustain settings and save games throughout updates. Also, this is necessary for AUR packages

Prerequisite for #871

Things to do:

• [x] Find out the best location to store data (home dir on linux. MacOS too? %APPDATA% on windows? Android?)
• [x] On startup, check if our settings file already exists on the new location. if yes, use it, if no copy over the existing one and use it
• [x] Re-enable writing error.log file to the new location
• [x] Change path of save games to the new location

I have all the prerequisites mentioned but after git cloning the repo and making a build directory inside, I try the command "cmake -DCMAKE_BUILD_TYPE=Release ../Cytopia" mentioned in the build instructions but slightly modified (".." instead of "../Cytopia" since my build directory is inside my Cytopia dir I think this is fine.) and get the following

Hello everyone, I just saw your reddit post and wanted to try out it this game. I followed the build instructions from the gitand there where no errors in the build, however when i try to run the game I get the start screen but then when I click on any button I get the error

Assertion failure at SDL_QueryTexture_REAL (../source_subfolder/src/render/SDL_render.c:727), triggered 1 time: 'texture && texture->magic == &texture_magic'

Some help would be appreciated.

I managed to implement OpenAL Soft to play sounds in 3D.

To test this, compile with cmake -DENABLE_SDL2_MIXER=1 -DENABLE_OPENAL_SOFT=1, and change settings.json 3DAudioStatus to true for 3D audio. Also wear stereo headphones or use a surround sound system.

Use the alsoft-config program that came with OpenAL Soft installation to set up the audio device for simulated 3D audio.

Changes for each class.

AudioMixer

• Uses Macro USE_OPENAL_SOFT to initialize specific OpenAL Soft variables such as gAudioDevice, alContext to initialize OpenAL Soft system to play 3D sound.
• If OpenAL Soft is enabled by USE_OPENAL_SOFT and 3d audio is set to be used, SDL mixer will initialize in mono, mono audio files will be loaded, OpenAL Soft will play 3D audio.
• If OpenAL Soft is enabled by USE_OPENAL_SOFT and 3d audio is not set to be used, SDL mixer will initialize in stereo, stereo audio files will be loaded, OpenAL Soft will play audio in stereo. -If OpenAL Soft is not enabled, SDL mixer will initialize in stereo, stereo audio files will be loaded, SDL_Mixer will play audio in stereo.

SoundTrack

• buffer added to contain audio data for OpenAL Soft to play in stereo or 3D audio.
• source added to contain position of object in 3D space for OpenAL Soft to localize where to play audio in 3D space. Buffer is attached to source.
• buffer and source is similar to Mix_Chunk and gets initialized and destroyed in the same places as Mix_Chunk.

SettingsData, JSONSerialization

• Added Audio3DAudioStatus variable to set 3D audio on or off through settings.json.
• Added AudioConfig3DJSONFile to specifically load only mono versions of sound for use with 3D effect as stereo audio files can't be localized in 3D space under OpenAL Soft.

Game

• If OpenAL Soft is enabled by USE_OPENAL_SOFT and 3D audio is set to be used, AudioMixer will play the theme as if the sound is coming from in front of you from the computer.

Changes outside of classes

• CMakeLists.txt changed to include OpenAL Soft as an optional dependency.
• conanfile.txt.in changed to include OpenAL Soft as a package to download.
• Mono versions of sound produced and added to resources folder to be used for 3D effect. 21 audio files added.

Hi. I try to build it for macOS

I install from homebrew cmake, git and conan. Then:

brew install cmake git conan
git clone https://github.com/CytopiaTeam/Cytopia.git
cd Cytopia
git submodule update --init --recursive
mkdir build && cd build
cmake -DCMAKE_BUILD_TYPE=Release ..
make -j8
cmake --build . --target package

I try cmake just like this cmake ...

I got always error

A duplicate of #634 with additional commits that automatically address incorrect style, created by Restyled.

Since the original Pull Request was opened as a fork in a contributor's repository, we are unable to create a Pull Request branching from it with only the style fixes.

The following Restylers made fixes:

• clang-format
• whitespace

To incorporate these changes, you can either:

1. Merge this Pull Request instead of the original, or

2. Ask your contributor to locally incorporate these commits and push them to the original Pull Request

   Expand for example instructions

   ```console
   git remote add upstream https://github.com/CytopiaTeam/Cytopia.git
   git fetch upstream pull/<this PR number>/head
   git merge --ff-only FETCH_HEAD
   git push
   ```
   

NOTE: As work continues on the original Pull Request, this process will re-run and update (force-push) this Pull Request with updated style fixes as necessary. If the style is fixed manually at any point (i.e. this process finds no fixes to make), this Pull Request will be closed automatically.

Sorry if this was unexpected. To disable it, see our documentation.

Currently, many items, like trees or flowers, are overplacable, which allows users to build over them without destroying them first. Using this feature, users are able to replace the same item on a tile over and over again to get different variations. However, one annoying aspect of this is how you can occasionally place the same frame, which makes it seem like the game didn't place the item at all.

Therefore, I am suggesting a feature that would prevent the user from overplacing the same variation twice. For example, if the user overplaces a tree that's using its third variation, the new tree will have a 0% chance of using the third variation. This will ensure that a new item variation is placed every time.

• remove logic for build menu with ui natives widgets
• draw build menu aligment inplace
• draw and create only need elements
• avoid creating textures for all buttons in buildmenu

Remove the ui buttons at the bottom of the game and replace it by a new UI. There are several ideas on the discord server, but be creative :)

We need to show following:

• Building Menu in categories and subcategories, like we have now. (Terrain Edit, Roads, Zones, Water, Power, Emergency, Parks, Debug)
• Money count
• Population count
• RCI demand Indicators
• Settings button
• GameSpeed buttons

why: common approach of enhancing this architecture is to move it more into a fork/join approach, where you have a main execution thread, and at some points, parts of the work is split between threads.

• add thread pool implementation for workers
• add scenes ideas for split game logic such mainmenu, loading, map

explanation: https://vkguide.dev/docs/extra-chapter/multithreading

When the player clicks on "New Game" Display a dialog with settings for terrain.

Following settings are available in TerrainGenerator.cxx:

struct TerrainSettings
{
  int mapSize = 128;
  int seed = 0;         // If the seed is 0, a random seed will be generated by TerrainGenerator::generateTerrain()
  int seaLevel = 2;     // All tiles with elevation below this will be set as water.
  int treeDensity = 50; // 0% no trees, 100% All trees everywhere all the time.
  int mountainAmplitude =
      10;              // Both amplifies the mountain noise source, as well as biasing the mountain/plains blend. Expects 0-100.
  int waterAmount = 5; // Density of freshwater in addition to coastlines and rivers. Expects 0-100.
  int coasts =
      1; // 4 least significant bits are bitmasked, where 0 is a land border and 1 is a coastline. Remaining bits reserved for future use.
  int rivers = 1;              ///< Number of rivers to attempt generating.
  std::string biomes = "{}";   ///< JSON string of biomes to attempt using, plus any options associated with them.
  std::string advanced = "{}"; ///< JSON string of arbitrary advanced option data for future use or mods.
};

We need UI Elements for:

• DropDown Map Size
• Textfield Seed
• Slider Water (0-100)
• Slider Foliage density (0-100)
• Slider Mountain height (0-100)
• Slider for sea level
• DropDown Biome
• Checkbox Rivers

Buttons:

• Generate
• OK

Right now setMusicVolume changes all sound volume, not just music, and setSoundEffectsVolume does nothing. It's been like this for a while, I just wanted to create an issue so it wasn't forgotten about.
