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 ( )

bool Swatter::updateAndTestFinished ( )

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.
