BROT

A lightweight game engine for lightweight 2D games.

How to use

• Installing SDL2.

# for arch based systems
sudo pacman -S sdl2 sdl2_image sdl2_ttf sdl2_mixer

Setup

Download, compile the source and install for include headers:

git clone https://github.com/Raisess/brot
cd brot
make all
make install

Headers

The headers are all on /usr/local/include/brot, so the path will be like this:

#include <brot/engine/core/Game.h>
#include <brot/engine/core/Scene.h>
#include <brot/engine/object/Entity.h>

Code Example

Draws a small square in the center of screen.

#include <brot/engine/core/Game.h>
#include <brot/engine/core/Scene.h>
#include <brot/engine/object/Entity.h>

using namespace Engine;

int main(int argc, char* arcv[]) {
  Game example("Example", argc, arcv);
  Scene main("main-scene");
  auto layer = main.push_layer();
  auto entity = Entity::Shared(example.ctx, "entity");
  layer->nodes.push_back(entity);

  entity->rect = true;
  entity->size = { 100, 100 };
  entity->position = example.ctx.window->get_size().xy() / 2;
  entity->offset = entity->size.xy().inverse() / 2;

  example.loop([&](int delta_time) {
    main.update(delta_time);
    main.draw();
  });

  return 0;
}

Compiling and running the Engine test program

NOTE: at this time I'm not providing the test assets, so you need to add your own to get this working...

make build_engine_test
