Note

For Kinoko, we introduce a slight performance improvement by early returning once the correct segment is found.

getCurrSegmentLength()

f32 Kinoko::Field::RailSmoothInterpolator::getCurrSegmentLength ( ) const

inlinenodiscardoverridevirtual0x806EF09C

getCurrVel()

f32 Kinoko::Field::RailSmoothInterpolator::getCurrVel ( )

inlinenodiscardoverridevirtual0x806EF93C

As a Kinoko-specific optimization, m_velocity calculation is deferred until this function is called, since few objects actually read the current velocity.

m_velocityPending

bool Kinoko::Field::RailSmoothInterpolator::m_velocityPending

private

Whether m_velocity needs to be recomputed from m_curPos and m_prevPos.

Kinoko-specific optimization. Few objects read getCurrSpeed(), so calc() defers computing m_velocity until it is read.
