An intuitive and beginner friendly 2D game framework for C++.

Features • How to build • Get Started • Screenshots • Showcase • Support

NasNas is a lightweight cross platform modular 2D game framework.

It is entirely written in modern C++17, and uses SFML2 for rendering.

It provides a clean and easy to use API.

The framework is separated in multiple modules :

• Core is the only non-optional module. It is needed to create a NasNas application. It contains core classes and data needed by the framework.
• ECS is an efficient data driven Entity Component System. It allows you to attach components to entities and run systems on specific sets of components.
• Reslib contains the resource manager and resource loader. It handles resource loading and accessing in an elegant way.
• Tilemapping is a Tiled Map loader (.tmx). It seamlessly integrates with NasNas and speeds up development for tile based games.
• Tween allows you to animate any object using the provided or custom easing functions.
• UI contains the User Interface utilities. (WIP)
• More modules will be developed in the future !

Features

Implemented :

• Scene and Layers system
• Cameras and Shaders
• Application states (using StateStackApp or StateMachineApp)
• Automatic resource loader and manager
• Data oriented ECS inspired by entt with a bunch of provided components and defaults systems.
• Tiled map loader (.tmx)
• Text and bitmap fonts
• Customizable Transitions
• Flexible Tween and MultiTween utilities.
• Extensible Particles system
• Multi texture SpriteBatching
• App configuration and settings
• Debug text display in-game
• Convenient console Logger
• And more !

To do :

• Menus and UI

Future :

• Splash screens
• Levels and game events management
• In-game command line for debugging

You can find a global roadmap for the version 1.0 on the project board

Build

Desktop

Clone the repository.

git clone https://github.com/Madour/NasNas
cd NasNas

Then, you can build the static libraries with :

mkdir build && cd build
cmake ..
cmake --build . -j4

Finally, you can install those libraries using :

cmake --install .

Android

To build the framework for Android, please refer to the Android example's readme

Available CMake options :

• -DNASNAS_BUILD_ECS=OFF to disable the ECS module

• -DNASNAS_BUILD_RESLIB=OFF to disable the Reslib module

• -DNASNAS_BUILD_TILEMAPPING=OFF to disable the Tilemapping module

• -DNASNAS_BUILD_TWEEN=OFF to disable the Tween module

• -DNASNAS_BUILD_UI=OFF to disable the UI module

• -DNASNAS_EXAMPLES=ON to create the example applications targets

• -DNASNAS_BUILD_SFML=ON to download and build SFML inside the project (enabled automatically if SFML package is not found)

• -DNASNAS_STATIC_VCRT=ON to link the Visual C++ runtime statically (/MT) when using the Microsoft Visual C++ compiler

Get Started

Here is a sample code using NasNas framework, this will create a 720x480 window and log a string to the console :

#include <NasNas/Core.hpp>

class Game : public ns::App {
public:
    Game() : ns::App("My game", 720, 480) {
        ns_LOG("Created a NasNas app !");
    }
    void onEvent(const sf::Event& event) override {
        if (event.type == sf::Event::Closed)
            getWindow().close();
    }
    void update() override {}
};

int main() {
    Game g;
    g.run();
    return 0;
}

An introduction tutorial to learn how to use the framework can be found on the wiki.

Documentation can be found here.

You can also check examples source code for a small overview of what you can do with the framework.

Screenshots

All of these programs source code can be found in the examples folder.
