The game's functionalities are organized into separate classes, utilizing Object-Oriented Programming (OOP) principles to make the codebase more modular and maintainable.
The Game class acts like the brain of the program, control various parts of the game.
TextureManagerclass is responsible for loading and rendering textures.SoundManagerclass is responsible for loading and playing sound effects.InputManagerclass is responsible for handling user input.- The
GameObjectclass is the base class for all game objects, which includes the player, enemies, bullets, ... Each of these classes inherits from theGameObjectclass and implements their own functionalities.
The core game loop is implemented in the Game class, which handle events -> update game objects -> render game objects -> repeat.
Update loop basically calls the GameStateManager class to handle the current state.
Most of state classes are also inherit from the MenuState class which base class is GameState.
These classes call StateParser class to parse the data from an external XML file which then render various game objects on the screen. The tinyxml2 library is used to parse the XML file.
The only exception is the PlayState class which call the LevelParser class instead. This class also parses the data from an external map file, but designed specifically for handling the Tiled map file format. The base64 and zlib libraries are used to decode the map data.
Due to the space between frame in some object sprite sheets, the collision detection is not pixel-perfect. Instead, the CollisionManager class check for outer edges of the object minus a fixed offset to determine the collision.

First, you need to make sure to have the following dependencies installed on your machine:
If you're running on Ubuntu, you can install them by running the following command:
sudo apt-get install -y libsdl2-dev libsdl2-2.0-0 libsdl2-image-dev libjpeg-dev libwebp-dev libtiff5-dev libsdl2-image-dev libsdl2-image-2.0-0 libmikmod-dev libfishsound1-dev libsmpeg-dev liboggz2-dev libflac-dev libfluidsynth-dev libsdl2-mixer-dev libsdl2-mixer-2.0-0 zlib1g-devTo build the project, navigate to the root directory and run the following command:
cmake -S . -B build
cmake --build buildIf the build process succeed, you can find the executable file in the build directory. To run the game, simply run the following command:
./build/Spectra
