A simple c++ w/SDL2 game engine

DOCS HAVE BEEN FINISHED HOLY HELL THAT TOOK SO LONG

DOCS

Examples

ICNTBall, a 2D metroidvania platformer

Quickstart

The main fuction

int main()
{   
    GameManager::init({1920, 1080});

    GameManager::createEntity("Player");

    GameManager::doUpdateLoop();
    return 0;
}

This is what the main should look like, the init() must be ran first and will also set the 'original' resolution, note that this should be set once and left because changing it will change game behavior

Entities

Entity* player = GameManager::createEntity("Player");

Entites can be created with the GameManager::createEntity method. In the instance above the Entity is given the tag "Player".

Components

Entity* background = GameManager::createEntity("Background");
background->add<Sprite>();
background->get<Sprite>()->loadTexture("img/background.png");

Entity* background2 = GameManager::createEntity("Background");
// Require adds or gets depending on if the entity has the component
background2->require<Sprite>()->loadTexture("img/background.png");

Components can be created an added (Kinda like scripts)

class Player : public Component {
    public:
    void start() override {
        entity->require<Sprite>()->loadTexture("img/player.png");
    }

    void update(float deltaTime) override {
        entity->get<Sprite>()->angle.lookAt(box->getBox().getCenter(), InputManager::getMousePosition());
    }
};

The start method will run during the component initalization Update will of course run every game loop And then can be added to Entities

Entity* player = createEntity("Player");
player->add<Player>();
