Member Function Documentation

void MWPhysics::Actor::addCollisionMask ( int  collisionMask )

private

Here is the caller graph for this function:

void MWPhysics::Actor::enableCollisionBody

(

bool

collision

)

Enables or disables the external collision body. If disabled, other actors will not collide with this actor.

Here is the call graph for this function:

Here is the caller graph for this function:

void MWPhysics::Actor::enableCollisionMode

(

bool

collision

)

Sets the collisionMode for this actor. If disabled, the actor can fly and clip geometry.

int MWPhysics::Actor::getCollisionMask ( )

private

Here is the caller graph for this function:

bool MWPhysics::Actor::getCollisionMode ( ) const

inline

Here is the caller graph for this function:

btCollisionObject* MWPhysics::Actor::getCollisionObject ( ) const

inline

Here is the caller graph for this function:

osg::Vec3f MWPhysics::Actor::getCollisionObjectPosition

(

)

const

Returns the position of the collision body

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.

Here is the call graph for this function:

Here is the caller graph for this function:

osg::Vec3f MWPhysics::Actor::getHalfExtents

(

)

const

Returns the half extents of the collision body (scaled according to collision scale)

Here is the caller graph for this function:

const osg::Vec3f& MWPhysics::Actor::getInertialForce ( ) const

inline

Gets the current amount of inertial force (incl. gravity) affecting this physic actor

Here is the caller graph for this function:

bool MWPhysics::Actor::getOnGround ( ) const

inline

Here is the caller graph for this function:

osg::Vec3f MWPhysics::Actor::getPosition

(

)

const

Here is the caller graph for this function:

osg::Vec3f MWPhysics::Actor::getPreviousPosition

(

)

const

Here is the caller graph for this function:

osg::Vec3f MWPhysics::Actor::getRenderingHalfExtents

(

)

const

Returns the half extents of the collision body (scaled according to rendering scale)

Note

The reason we need this extra method is because of an inconsistency in MW - NPC race scales aren't applied to the collision shape, most likely to make environment collision testing easier. However in some cases (swimming level) we want the actual scale.

Here is the caller graph for this function:

bool MWPhysics::Actor::isWalkingOnWater

(

)

const

Here is the caller graph for this function:

Actor& MWPhysics::Actor::operator= ( const Actor &  )

private

void MWPhysics::Actor::setCanWaterWalk

(

bool

waterWalk

)

Sets whether this actor should be able to collide with the water surface.

Here is the call graph for this function:

Here is the caller graph for this function:

void MWPhysics::Actor::setInertialForce

(

const osg::Vec3f &

force

)

Sets the current amount of inertial force (incl. gravity) affecting this physic actor

Here is the caller graph for this function:

void MWPhysics::Actor::setOnGround

(

bool

grounded

)

Here is the caller graph for this function:

void MWPhysics::Actor::setPosition

(

const osg::Vec3f &

position

)

Store the current position into mPreviousPosition, then move to this position.

Here is the call graph for this function:

Here is the caller graph for this function:

void MWPhysics::Actor::setWalkingOnWater

(

bool

walkingOnWater

)

Sets whether this actor has been walking on the water surface in the last frame.

Here is the caller graph for this function:

void MWPhysics::Actor::updateCollisionMask ( )

private

Removes then re-adds the collision object to the dynamics world.

Here is the call graph for this function:

void MWPhysics::Actor::updateCollisionObjectPosition

(

)

Here is the call graph for this function:

Here is the caller graph for this function:

void MWPhysics::Actor::updatePosition

(

)

Set mPosition and mPreviousPosition to the position in the Ptr's RefData. This should be used when an object is "instantly" moved/teleported as opposed to being moved by the physics simulation.
