createBody()

void Moveable::createBody	(	float	mass,
		btTransform &	trans,
		btCollisionShape *	shape,
		float	restitution
	)

Creates the bullet rigid body for this moveable.

Parameters

mass	Mass of this object.
trans	Transform (=position and orientation) for this object).
shape	Bullet collision shape for this object.

flyUp()

void Moveable::flyUp ( )

virtual

Enter flying mode.

Reimplemented in Kart.

getIdent()

virtual const std::string & Moveable::getIdent ( ) const

inlinevirtual

Reimplemented in AbstractKart.

getRoll()

float Moveable::getRoll ( ) const

inline

Returns the roll of the kart between -pi and pi.

getVelocity()

virtual const btVector3 & Moveable::getVelocity ( ) const

inlinevirtual

Reimplemented in Cake.

reset()

void Moveable::reset ( )

virtual

The reset position must be set before calling reset.

Reimplemented in AbstractKart, Flyable, GhostKart, Kart, KartRewinder, and KartWithStats.

setNode()

void Moveable::setNode

(

scene::ISceneNode *

n

)

Sets the mesh for this model.

Parameters

n	The scene node.

setTrans()

void Moveable::setTrans

(

const btTransform &

t

)

Places this moveable at a certain location and stores this transform in this Moveable, so that it can be accessed easily.

Parameters

t	New transform for this moveable.

setVelocity()

virtual void Moveable::setVelocity ( const btVector3 &  v )

inlinevirtual

Reimplemented in Cake.

setXYZ()

virtual void Moveable::setXYZ ( const Vec3 &  a )

inlinevirtual

Sets the XYZ coordinates of the moveable.

Reimplemented in Kart.

update()

void Moveable::update ( int  ticks )

virtual

Updates the current position and rotation from the corresponding physics body, and then calls updateGraphics to position the model correctly.

Parameters

ticks

Number of physics time steps - should be 1.

Reimplemented in GhostKart, Kart, KartRewinder, and KartWithStats.

updateGraphics() [1/2]

void Moveable::updateGraphics ( const Vec3 &  offset_xyz = Vec3(0.0f, 0.0f, 0.0f), const btQuaternion &  rotation = btQuaternion(0.0f, 0.0f, 0.0f, 1.0f)  )

protectedvirtual

Updates the graphics model.

Mainly set the graphical position to be the same as the physics position, but uses offsets to position and rotation for special gfx effects (e.g. skidding will turn the karts more).

Parameters

offset_xyz	Offset to be added to the position.
rotation	Additional rotation.

updateGraphics() [2/2]

virtual void Moveable::updateGraphics ( float  dt )

pure virtual

Called once per rendered frame.

It is used to only update any graphical effects.

Parameters

dt	Time step size (since last call).

Implemented in Flyable, Plunger, GhostKart, Kart, and KartRewinder.

updatePosition()

void Moveable::updatePosition

(

)

Updates the current position and rotation.

This function is also called by ghost karts for getHeading() to work.
