Detailed Description

Owns the Bullet btDiscreteDynamicsWorld and all auxiliary collision structures (broadphase, dispatcher, solver).

One instance lives on the Engine singleton. PhysicsComponent pushes its RigidBody here via AddRigidBody; Engine::Run calls Update once per frame to step the simulation.

◆ Raycast()

bool mnd::PhysicsManager::Raycast	(	const vec3 &	from,
		const vec3 &	to,
		RayHit &	out
	)

Cast a ray from from to to and fill out with the closest hit. out.object is the GameObject behind the hit collision object, when one has been set via CollisionObject::SetOwner; otherwise null.
