Member Function Documentation

◆ getHitEffect()

virtual HitEffect * Plunger::getHitEffect ( ) const

inlinevirtual

No hit effect when it ends.

Reimplemented from Flyable.

◆ hit()

bool Plunger::hit	(	AbstractKart *	kart,
		PhysicalObject *	obj = `NULL`
	)

virtual

Virtual function called when the plunger hits something.

The plunger is special in that it is not deleted when hitting an object. Instead it stays around (though not as a graphical or physical object) till the rubber band expires.

Parameters

kart	Pointer to the kart hit (NULL if not a kart).
obj	Pointer to PhysicalObject object if hit (NULL otherwise).

Returns: True if there was actually a hit (i.e. not owner, and target is not immune), false otherwise.

Reimplemented from Flyable.

◆ hitTrack()

void Plunger::hitTrack ( )

virtual

Called when the plunger hits the track.

In this case, notify the rubber band, and remove the plunger (but keep it alive).

Reimplemented from Flyable.

◆ onDeleteFlyable()

void Plunger::onDeleteFlyable ( )

virtual

Reimplemented from Flyable.

◆ onFireFlyable()

void Plunger::onFireFlyable ( )

virtual

Call when the item is (re-)fired (during rewind if needed) by projectile_manager.

Reimplemented from Flyable.

◆ restoreState()

void Plunger::restoreState	(	BareNetworkString *	buffer,
		int	count
	)

virtual

Called when a state needs to be replayed.

This is called during rewind, i.e. when going forward in time again, and only for confirmed states.

Reimplemented from Flyable.

◆ saveState()

BareNetworkString * Plunger::saveState ( std::vector< std::string > * ru )

virtual

Provides a copy of the state of the object in one memory buffer.

The memory is managed by the RewindManager.

Parameters

[out] ru The unique identity of rewinder writing to.

Returns: The address of the memory buffer with the state.

Reimplemented from Flyable.

◆ setKeepAlive()

void Plunger::setKeepAlive ( int16_t ticks )

inline

Sets the keep-alive value.

Setting it to 0 will remove the plunger at the next update - which is used if the rubber band snaps.

◆ updateAndDelete()

bool Plunger::updateAndDelete ( int ticks )

virtual

Updates the plunger in each frame.

If this function returns true, the object will be removed by the projectile manager.

Parameters

dt	Time step size.

Returns: True of this object should be removed.

Reimplemented from Flyable.

◆ updateGraphics()

void Plunger::updateGraphics ( float dt )

virtual

Called once per rendered frame.

It is used to only update any graphical effects.

Parameters

dt	Time step size (since last call).

Reimplemented from Flyable.
