Member Data Documentation

DtRwBoolean DtRoadMovementDescriptor::myClampToGround

protected

Parameter Name: clamp-to-ground
Parameter Description: Specifies whether or not to clamp to the terrain when moving the entity.

If not clamped, the entity is positioned on the road segment, which is assumed to be planar. This is much cheaper, computationally, than looking up a terrain elevation. If this parameter is false, then use-high-fidelity-ground-clamping is ignored.
Parameter Default Value: True

DtRwBoolean DtRoadMovementDescriptor::myUseHighFidelityGroundClamping

protected

Parameter Name: use-high-fidelity-ground-clamping
Parameter Description: Specifies whether or not to use all four of the entity's support points when determining the orientation/placement of the entities, or to use just the center support point.

For most entities on most terrains, the single support point is an acceptable trade-off, but the default value is true to ensure more correct behavior in general. For complex terrains, large numbers of ground entities (especially individual platform entities), this can be a noticeable performance improvement.
Parameter Default Value: True

Note

Implementation Detail: This only affects the placement of entities in the update() function, when calculating orientation, and does not affect general placement, which is done through the entity state repository.

DtRwReal DtRoadMovementDescriptor::myConvoySpeedFactor

protected

Parameter Name: convoy-follow-speed-factor
Parameter Description: This is the factor by with to multiply our ordered speed to allow us to catch up/slow down to get within the follow threshold of the convoy follow distance.

Parameter Default Value: 1.2;

DtRwObjectTypeList DtRoadMovementDescriptor::myPassableObjectTypes

protected

Parameter Name: passable-object-types
Parameter Description: Object types to treat as potential obstructions that we can drive around.

Parameter Default Value:

DtRwUnsigned DtRoadMovementDescriptor::myExtraLanes

protected

Parameter Name: extra-lanes-each-direction
Parameter Description: Extra lanes added to each direction of path segments.

Parameter Default Value: 0
