Tela

C++ multimedia and game-development library. Windowing, 2D rendering, and input via a pluggable backend system — no SDL or other intermediary.

Current: Linux · Wayland · OpenGL/EGL
Planned: Windows, X11, Vulkan

Dependencies

# Debian/Ubuntu — Wayland + OpenGL backend
sudo apt install libwayland-dev libdecor-0-dev wayland-protocols \
                 libgl-dev libegl-dev libepoxy-dev

Build

make          # builds libtela.a
make examples # builds libtela.a + examples

CMake directly:

cmake -S . -B build -DBUILD_EXAMPLES=ON
cmake --build build --parallel

Backend/renderer selection:

CMake option	Values	Default
PROJECT_PLATFORM	linux	linux
PROJECT_BACKEND	wayland	wayland
PROJECT_RENDERER	opengl	opengl

Usage

#include <tela/app.hpp>
#include <tela/input.hpp>

class MyScene : public tela::Scene {
public:
    MyScene() { add_child(player_); }

private:
    Player player_;
};

int main() {
    tela::App app({ .width = 800, .height = 600, .title = "My Game" });
    app.run<MyScene>();
}

Node Types

Type	Purpose
Node	Base; override process(float) and draw(Renderer&)
Scene	Root of the tree; owned by App
Timer	Fires a callback after a duration; start() / stop()
Node2D	Positioned node with set_position() / size() / set_rotation()
Sprite2D	Renders a texture; constructed from a ResourcePath or a Texture2D

Assets resolve via tela::Resources::path("assets/foo.png") relative to the binary. Input goes through the static tela::Input API; see examples/input.
