Hey, I've implemented a simple circle collision detection system.
bool SEMath::circle_collision(const TVector& a, const TVector& b,
const float& r1, const float& r2)
{
// (x2-x1)^2 + (y2-y1)^2 <= (r1+r2)^2
float center_distance = square(b.x - a.x) + square(b.y - a.y);
float collision_distance = square(r1 + r2);
return center_distance <= collision_distance;
}
Upon collision, self circle will get it's opposite velocity (to bounce back) and the collided circle will get the get the velocity it was hit with:
CollidedActor->setVelocity(InActor->getVelocity());
InActor->setVelocity(InActor->getVelocity() * -1.f);
This works fine. But it's just a linear response. What I want is to consider at what angle the circles are colliding as well to be able to simulate a billiard like game by taking into account angular velocity as well but I have no idea how to approach this, any directions would be greatly appreciated. Thanks!
