2d collision with tinyc2

collision2d

A small wrapper around tinyc2 using SFML's sf::Vector2f (for now).

Features

• For now circles, aabbs and rays are the only supported shape types
• Manifolds and raycasts can be calculated for all supported shapes

How to use

If you are already using SFML and tinyc2, it should be enough to add Collision.hpp and Collision.cpp to your project.
Then create your shapes

std::unique_ptr<Shape> shapeA = std::make_unique<Circle>(30.0f);
std::unique_ptr<Shape> shapeB = std::make_unique<Aabb>(60.0f, 80.0f);

Calculate a manifold

Manifold m;
m = solve(*shapeA, sf::Vector2f(300.0f, 200.0f), *shapeB, sf::Vector2f(250.0f, 250.0f));

And solve the collision

if (m.colliding)
{
        positionA -= m.normal * m.depth;
}
