Detailed Description

DtHumanMovementActuator is a simple movement actuator for lifeforms.

Developer Description: It moves in the requested speed (clamped by the max speed of the entity) and direction. The entity will speed up, slow down, and turn instantly when the requested values change.

Uses Descriptor Type: DtHumanMovementActuatorDescriptor

virtual void DtHumanMovementActuator::computeAndSetPosture ( )
protectedvirtual

The main method for everything to do with posture in this actuator.

This determines the correct posture based on the input port and speed of the entity, and then sets this posture to the state repository.

virtual DtLifeformState DtHumanMovementActuator::computeDynamicPosture ( DtLifeformStaticPosture  staticPosture)
protectedvirtual

Determines the correct dynamic posture for the entity based on the desired static posture passed in, and the current state of the entity.

virtual DtLifeformStaticPosture DtHumanMovementActuator::restrictPostureForTerrain ( DtLifeformStaticPosture  desiredPosture)
protectedvirtual
Returns
The static posture closest to the desired posture that is allowed on the current terrain. For example, standing upright on a steep hill is not allowed, so the return would be prone.
virtual bool DtHumanMovementActuator::checkForTerrainCollisions ( ) const
protectedvirtual
Returns
Boolean signifying whether or not the terrain should be checked for collisions with the entity's bounding volume while it moves. If this returns true, the entity will not move through the terrain. If this is false, it may move through terrain polygons, such as building walls when moving to a new location.
Note
it currently just returns the value of the user specified parameter in the automotivePSR.
virtual bool DtHumanMovementActuator::checkBlockedByTerrain ( const DtVector oldLocalPosition,
DtVector newLocalProjectedLocation 
)
protectedvirtual

Checks for terrain polygons between specified old and new positions.

virtual double DtHumanMovementActuator::maxUprightTerrainPitch ( ) const
protectedvirtual
Returns
Maximum terrain pitch at which entity can maintain a static upright posture (i.e. standing posture). Actuator will switch to a prone posture when terrain pitch exceeds this value. Units in radians. Returns value from myHumanMovementActuatorDescriptor if it exists, otherwise, returns 0.5236 (30 degrees) by default.
virtual double DtHumanMovementActuator::maxWalkingSpeed ( ) const
protectedvirtual
Returns
Maximum speed at which entity will walk. Actuator will switch from a walking posture to a running posture when current speed exceeds this value. Returns value from myHumanmovementActuatorDescriptor if it exists, otherwise returns 2.0 by default. Units in meters/second.
virtual void DtHumanMovementActuator::initializeStaticToDynamicPostureMap ( )
protectedvirtual

Initializes contents of myStaticToDynamicPostureMap, used.
