示例1: MaxSpeed
void CShadowController::MaxSpeed( const Vector &velocity, const AngularImpulse &angularVelocity )
{
IVP_Core *pCore = m_pObject->GetObject()->get_core();
// limit additional velocity to that which is not amplifying the current velocity
IVP_U_Float_Point ivpVel;
ConvertPositionToIVP( velocity, ivpVel );
IVP_U_Float_Point available = ivpVel;
m_currentSpeed = ivpVel;
// normalize and save length
float length = ivpVel.real_length_plus_normize();
float dot = ivpVel.dot_product( &pCore->speed );
if ( dot > 0 )
{
ivpVel.mult( dot * length );
available.subtract( &ivpVel );
}
IVP_Float_PointAbs( m_shadow.maxSpeed, available );
// same for angular, project on to current and remove redundant (amplifying) input
IVP_U_Float_Point ivpAng;
ConvertAngularImpulseToIVP( angularVelocity, ivpAng );
IVP_U_Float_Point availableAng = ivpAng;
float lengthAng = ivpAng.real_length_plus_normize();
