Syntax

[RequireComponent(typeof(Agent))]
[AddComponentMenu("ML Agents/Demonstration Recorder", 0)]
public class DemonstrationRecorder : MonoBehaviour

Remarks

Add this component to the GameObject containing an Agent to enable recording the agent for imitation learning. You must implement the Heuristic(ActionBuffers) function of the agent to provide manual control in order to record demonstrations.

See Imitation Learning - Recording Demonstrations for more information.

Fields

DemonstrationDirectory

Directory to save the demo files. Will default to a "Demonstrations/" folder in the Application data path if not specified.

Declaration

[FormerlySerializedAs("demonstrationDirectory")]
[Tooltip("Directory to save the demo files. Will default to {Application.dataPath}/Demonstrations if not specified.")]
public string DemonstrationDirectory

Field Value

Type	Description
String

DemonstrationName

Base demonstration file name. If multiple files are saved, the additional filenames will have a sequence of unique numbers appended.

Declaration

[FormerlySerializedAs("demonstrationName")]
[Tooltip("Base demonstration file name. If multiple files are saved, the additional filenames will have a unique number appended.")]
public string DemonstrationName

Field Value

Type	Description
