Detailed Description

This class implements a check sphere that is used to change the ambient light if a kart is inside this sphere.

Besides a normal radius this sphere also has a 2nd 'inner' radius: player karts inside the inner radius will have the full new ambient light, karts outside the default light, and karts in between will mix the light dependent on distance.

Member Function Documentation

◆ clone()

virtual CheckStructure * CheckCylinder::clone ( )

inlinevirtual

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

Implements CheckStructure.

◆ isTriggered()

bool CheckCylinder::isTriggered	(	const Vec3 &	old_pos,
		const Vec3 &	new_pos,
		int	kart_id
	)

virtual

True if going from old_pos to new_pos enters or leaves this cylinder.

This function is called from update (of the checkline structure). It also updates the flag about which karts are inside

Parameters

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

Implements CheckStructure.

Member Data Documentation

◆ m_distance2

std::vector<float> CheckCylinder::m_distance2

private

Stores the distance of each kart from the center of this sphere.

This saves some computations.
