#include <channel.h>

Class Description

Channels define preferred navigation areas around an original Path section on NavMesh.

They are typically used to drive bots which inertia prevent to use reactive path follower to drive it correctly along the original path itself.

Trajectory provides a spline mode that needs a Channel to compute splines to drive the bot.

Inherits Kaim::RefCountBase< C, Stat >.

Member Function Documentation

const Vec3f & Kaim::Channel::GetEndPos ( ) const

inline

Returns the channel end position, i.e.

the m_pathPos of its last Gate.

Precondition: The Channel must not be empty.

KyUInt32 Kaim::Channel::GetFirstPathNodeIdx ( ) const

inline

Return PathNodeIdx of the first gate.

KyUInt32 Kaim::Channel::GetGatePathNodeIdx ( KyUInt32 gateIndex ) const

inline

Return PathNodeIdx of the gate at gateIndex.

KyResult Kaim::Channel::GetSectionFromPositionAndSeed	(	const Kaim::Vec3f &	previousPosition,
		KyUInt32	previousSectionIdx,
		const Kaim::Vec3f &	newPosition,
		KyUInt32 &	newSectionIdx
	)		const

Given a previous position and its section, computes the section for a new position that is supposed to be near the previous one.

KyResult Kaim::Channel::GetSectionFromPositionAndSeed_AlongBubble	(	const Bubble &	bubble,
		const Kaim::Vec3f &	previousPosition,
		KyUInt32	previousSectionIdx,
		const Kaim::Vec3f &	newPosition,
		KyUInt32 &	newSectionIdx
	)		const

Given a previous position and its section, computes the section for a new position that is supposed to be accessible from the previous one following a circle arc.

bool Kaim::Channel::IsPositionInSection	(	const Vec2f &	position,
		KyUInt32	sectionIndex,
		KyUInt32 &	positionFlags
	)		const

Checks a provided 2D position is inside a channel section.

It updates positionFlags with a combination of the RelativePositionToChannelSectionFlag.

bool Kaim::Channel::IsPositionInSection	(	const Vec2f &	position,
		KyUInt32	sectionIndex
	)		const

inline

Just checks a provided 2D position is inside a channel section.
