Sinopsis

It is a simple 2d game demo with physics written in C++ using Unity3d-like gameobject/component system. I've tried to make it easy to extend and to upgrade

Code example

1. Add new empty GameObject to game world.

  auto& newGameObject = scene.createGameObject();

2. Add Physics component to this object. All components require GameObject reference. And physComponent needs some physics info: mass, static or dynamic, is affected by gravity or not.

  newGameObject.addComponent("Physics", new PhysComponent(newGameObject, 0.0f, false, false));

3. We can get component from GO by name.

  const auto currentPhysComponent = newGameObject.getComponent<PhysComponent>("Physics")

4. Set the collider of physComponent.

  currentPhysComponent -> setCollider(Collider::rectangleCollider(sf::Vector2f(1.0f,3.0f));

5. Set GameObject's position.

  newGameObject.getTransform().position = sf::Vector2f(3.0f,4.0f);

Installation

You will need SFML library to compile it.
