Constructor & Destructor Documentation

RigidBody()

mnd::RigidBody::RigidBody	(	BodyType	type,
		const std::shared_ptr< Collider > &	collider,
		float	mass,
		float	friction
	)

Parameters

type	Simulation category.
collider	Shape used for collision (shared — the same Collider may back several bodies).
mass	Kilograms; ignored for Static bodies.
friction	Bullet friction coefficient in [0, 1].

References mnd::CollisionObject::m_contactListeners.

EnableCcd()

void mnd::RigidBody::EnableCcd	(	float	motionThreshold,
		float	sweptRadius
	)

Enable continuous collision detection (prevents tunneling for fast bodies). motionThreshold: velocity per step above which CCD kicks in (set < expected step distance). sweptRadius: embedded sphere radius used for the swept test (typically ~0.2× shape radius).
