unreal.PlanarVelocityObservation

class unreal.PlanarVelocityObservation(outer: Object | None = None, name: Name | str = 'None')

Bases: LearningAgentsObservation

An observation of a velocity projected onto a plane.

C++ Source:

  • Plugin: LearningAgents

  • Module: LearningAgents

  • File: LearningAgentsObservations.h

Editor Properties: (see get_editor_property/set_editor_property)

  • interactor (LearningAgentsInteractor): [Read-Only] Reference to the Interactor this observation is associated with.

classmethod add_planar_velocity_observation(interactor, name='None', scale=200.000000, axis0=[1.000000, 0.000000, 0.000000], axis1=[0.000000, 1.000000, 0.000000]) → PlanarVelocityObservation

Adds a new planar velocity observation to the given agent interactor. The axis parameters define the plane. Call during ULearningAgentsInteractor::SetupObservations event.

Parameters:

  • interactor (LearningAgentsInteractor) – The agent interactor to add this observation to.

  • name (Name) – The name of this new observation. Used for debugging.

  • scale (float) – Used to normalize the data for the observation.

  • axis0 (Vector) – The forward axis of the plane.

  • axis1 (Vector) – The right axis of the plane.

Returns:

The newly created observation.

Return type:

PlanarVelocityObservation

set_planar_velocity_observation(agent_id=-1, velocity, relative_rotation=[0.000000, 0.000000, 0.000000]) → None

Sets the data for this observation. The relative rotation can be used to make this observation relative to the agent’s perspective, e.g. by passing the agent’s forward rotation. Call during ULearningAgentsInteractor::SetObservations event.

Parameters:

  • agent_id (int32) – The agent id this data corresponds to.

  • velocity (Vector) – The velocity currently being observed.

  • relative_rotation (Rotator) – The frame of reference rotation.
