示例1: DoSimulationDrag
//-----------------------------------------------------------------------------
// Purpose: Water drag.
//-----------------------------------------------------------------------------
void IVP_Controller_Raycast_Airboat::DoSimulationDrag( IVP_Raycast_Airboat_Pontoon_Temp *pTempPontoons,

{
// Get the forward vector in world-space.

matWorldFromCore->get_col( IVP_COORDINATE_INDEX( index_z ), &vecForwardWS );
// Get the airboat speed and direction.
IVP_U_Float_Point vecAirboatDir = pAirboatCore->speed;
vecAirboatDir.normize();
IVP_FLOAT flSpeed = ( IVP_FLOAT )pAirboatCore->speed.real_length();
IVP_FLOAT flSpeed2 = flSpeed * flSpeed;
// Increase drag the more perpendicular the airboat gets to the direction of motion.
// IVP_FLOAT flDragTurnScale = vecAirboatDir.dot_product( &vecForwardWS );
// flDragTurnScale = ( 1.0f - flDragTurnScale ) + 1.0f;
// Calculate the drag.

// Apply the drag force opposite to the direction of motion.
