Detailed Description

Implements a simple lap test.

A new lap is detected when the distance along the track reduces by a certain amount of time.

Constructor & Destructor Documentation

CheckLap()

CheckLap::CheckLap	(	const XMLNode &	node,
		unsigned int	index
	)

Constructor for a lap line.

Parameters

check_manager	Pointer to the check manager, which is needed when resetting e.g. new lap counters.
node	XML node containing the parameters for this checkline.

Member Function Documentation

clone()

virtual CheckStructure * CheckLap::clone ( )

inlinevirtual

Clone to child process for server usage (atm no sound or scripting).

Implements CheckStructure.

isTriggered()

bool CheckLap::isTriggered ( const Vec3 &  old_pos, const Vec3 &  new_pos, int  kart_index  )

virtual

True if going from old_pos to new_pos crosses this checkline.

This function is called from update (of the checkline structure).

Parameters

old_pos	Position in previous frame.
new_pos	Position in current frame.
kart_index	Index of the kart, can be used to store kart specific additional data.

Implements CheckStructure.

reset()

void CheckLap::reset ( const Track &  track )

virtual

Initialises the 'previous positions' of all karts with the start position defined for this track.

Parameters

track

The track object defining the start positions.

Reimplemented from CheckStructure.

triggeringCheckline()

virtual bool CheckLap::triggeringCheckline ( ) const

inlinevirtual

Reimplemented from CheckStructure.
