AsteroidsGame
Yet Another Asteroids Game
This game was made as part of admission tests for MIPT GameDev Master Program.
Installation
cmake . from project root to build. The binary would be in project's bin folder. You can move it to /usr/local/bin. All resources are contained inside binary.
You can also try to run binaries from bin folder. MacOS binary was built on Big Sur 11.4. Linux binary was build in docker container. Commands to reproduce:
docker build . -t asteroidsbuild
docker run --volume /path/to/project/root:/app asteroidsbuild /bin/bash -c "cmake ../ && cmake --build ."
Gameplay
Left/Right to rotate. Upto Boost. Space to shoot. Game can paused at any moment with Esc key.
After crash you will be invicible for a few second. Your ship will blink. Crashing into asteroids also destoies them. Smaller asteroids will give you more score.
You can play in Infinite Mode where you have 3 lives and infinitly spawning asteroids or complete levels with fixed amount of asteroids.
In levels, asteroids movement is seamless with respect to bordres of the screen. In Infite mode it also seamless but the border is a bit wider then sceen.
Starship movement is always seamless.
Levels progress is stored on disk between game launches in /tmp folder.
Framework
Engine.h and Engine.cpp were provided and not modified. Game uses stb_images.h and stb_truetype for image and font processing.
Most of gameplay logic code can be found in GameFieldScene class. It draws game field and manages starship, asteroids and projectiels behaviour.
Geometry.cpp containes set of classes for processing points, lines and paths.
GameObject.cpp defines base GameObject class and bunch of game object that used in game: Starship, Asteroid, Projectile, TextObject, Star, Planet etc.
Scene.h defines base class for scenes, which are also game object. The difference is that scenes can containe and manipulate other game objetc. Main purpose of scenes is to describe logic inside one game screen (scene). Usually one Scene child defines one actual scene.
MenuScene.cpp and MenuScene.h containes UI scenes classes. Mostly different kind of menus.
MenuItem.cpp and MenuItem.h container UI game object classes.
SceneManeger.cpp implements manager that controls switching scenes for scene layers. There are 3 scene layers: Background, Game Field and UI. The only difference is rasterization order.
Rasterizer.cpp implements different kinds of rasterization algorithms used for drawing game objects and scenes.
GameState.h defines global game variables like lives and score that are accessble to all scene and game objects.
Settings
To modify some parameters before build you can tune macros values inside MagicNumbers.h. For example you can change MAX_ASTEROIDS_SIZE to 6 if think that they are too big.
