void MWPhysics::PhysicsSystem::getActorsCollidingWith	(	const MWWorld::ConstPtr &	object,
		std::vector< MWWorld::Ptr > &	out
	)		const

Get the handle of all actors colliding with object in this frame.

Here is the call graph for this function:

void MWPhysics::PhysicsSystem::getActorsStandingOn	(	const MWWorld::ConstPtr &	object,
		std::vector< MWWorld::Ptr > &	out
	)		const

Get the handle of all actors standing on object in this frame.

osg::Vec3f MWPhysics::PhysicsSystem::getCollisionObjectPosition

(

const MWWorld::ConstPtr &

actor

)

const

Get the position of the collision shape for the actor. Use together with getHalfExtents() to get the collision bounds in world space.

Note

The collision shape's origin is in its center, so the position returned can be described as center of the actor collision box in world space.

const

Get physical half extents (scaled) of the given actor.

Here is the call graph for this function:

float MWPhysics::PhysicsSystem::getHitDistance	(	const osg::Vec3f &	point,
		const MWWorld::ConstPtr &	target
	)		const

Get distance from point to the collision shape of target. Uses a raycast to find where the target vector hits the collision shape and then calculates distance from the intersection point. This can be used to find out how much nearer we need to move to the target for a "getHitContact" to be successful.

Note

Only Actor targets are supported at the moment.

Here is the caller graph for this function:

bool MWPhysics::PhysicsSystem::isActorCollidingWith	(	const MWWorld::Ptr &	actor,
		const MWWorld::ConstPtr &	object

bool MWPhysics::PhysicsSystem::isActorStandingOn	(	const MWWorld::Ptr &	actor,
		const MWWorld::ConstPtr &	object
	)		const

Return true if actor has been standing on object in this frame This will trigger whenever the object is directly below the actor. It doesn't matter if the actor is stationary or moving.

void MWPhysics::PhysicsSystem::markAsNonSolid

(

const MWWorld::ConstPtr &
