Detailed Description

This class implements a check point like item, but used only for scripting or sound trigger.

Constructor & Destructor Documentation

CheckTrigger()

CheckTrigger::CheckTrigger	(	const Vec3 &	center,
		float	distance,
		std::function< void(int)>	triggering_function
	)

Constructor for a check trigger.

Parameters

center	Center point of this trigger
distance	Kart within it between center will trigger
triggering_function	callback function to be used when triggered

Member Function Documentation

trigger()

virtual void CheckTrigger::trigger ( unsigned int  kart_index )

inlinevirtual

Is called when this check structure is triggered.

This then can cause a lap to be counted, animation to be started etc.

Reimplemented from CheckStructure.

Member Data Documentation

m_center

const Vec3 CheckTrigger::m_center

private

Center of the trigger.

m_distance2

const float CheckTrigger::m_distance2

private

Squared of the triggering distance.

m_last_triggered_time

uint64_t CheckTrigger::m_last_triggered_time

private

Time since last trigger, if any triggering between 2 seconds ignored (like items).

m_triggering_function

const std::function<void(int)> CheckTrigger::m_triggering_function

private

Function to call when triggered.
