virtual bool DtRailObstructionAnalyzer::closestObstructionInLane ( int  lane, const std::list< DtRailObstructionPtr > &  obstructionList, DtRailObstructionPtr &  obstruction, bool  checkForwardOnly  ) const

virtual

Finds the closest obstruction in the list that blocks the specified lane.

Parameters

obstruction

The returned obstruction, if found.

Returns

True if any obstruction is found.

Note

This function using the current positions of the obstructions, and does not take any obstruction velocities into account.

virtual bool DtRailObstructionAnalyzer::firstHitObstructionInLane ( int  lane, double  railVelocity, double  railStartOffset, const std::list< DtRailObstructionPtr > &  obstructionList, DtRailObstructionPtr &  obstruction, double &  hitTime  ) const

virtual

Finds the first obstruction that will be hit in the specified lane, using the specified velocity along the rail. This uses the positions and velocities of the obstructions in the list.

Parameters

obstruction	The returned obstruction.
hitTime	The amount of time before the collision would occur.
railVelocity	The velocity along the rail which the entity doing this check is traveling.
railStartOffset	The distance ahead from 0 on the rail that is considered part of the entity doing this check. Typically 0 is the entity center, so this is the half length of the entity.

Returns

True if any obstruction is found.

virtual bool DtRailObstructionAnalyzer::timeToHit ( double  railVelocity, double  railStartOffset, const DtRailObstructionPtr &  obstruction, double &  hitTime  ) const
