Member Enumeration Documentation

AnimationPhase

enum Swatter::AnimationPhase : uint8_t

private

State of the animation, the swatter is successively:

• aiming (default state) => it's turning to the nearest target
• going down to the target
• going up from the target

Constructor & Destructor Documentation

Swatter()

Swatter::Swatter	(	AbstractKart *	kart,
		int16_t	bomb_ticks,
		int	ticks,
		Attachment *	attachment
	)

Constructor: creates a swatter at a given attachment for a kart.

If there was a bomb attached, it triggers the replace bomb animations.

Parameters

attachment	The attachment instance where the swatter is attached to.
kart	The kart to which the swatter is attached.
bomb_ticks	Remaining bomb time in ticks, -1 if none.
ticks	Swatter duration.
attachment	class attachment from karts.

Member Function Documentation

isSwatterReady()

bool Swatter::isSwatterReady ( ) const

inline

Returns if the swatter is currently aiming, i.e.

can be used to swat an incoming projectile.

pointToTarget()

void Swatter::pointToTarget ( )

private

If there is a current target, point to it, otherwise adopt the default position.

If there is a current target, point in its direction, otherwise adopt the default position.

restoreState()

void Swatter::restoreState ( BareNetworkString *  buffer )

virtual

Reimplemented from AttachmentPlugin.

saveState()

void Swatter::saveState ( BareNetworkString *  buffer ) const

virtual

Reimplemented from AttachmentPlugin.

updateAndTestFinished()

bool Swatter::updateAndTestFinished ( int  ticks )

virtual

Updates an armed swatter: it checks for any karts that are close enough and not invulnerable, it swats the kart.

Parameters

ticks

Time step size.

Returns

True if the attachment should be discarded.

Implements AttachmentPlugin.
