Class GridSensorComponent
A SensorComponent that creates a GridSensorBase.
Namespace: Unity.MLAgents.Sensors
Syntax
public class GridSensorComponent : SensorComponentFields
m_SensorName
Declaration
protected string m_SensorNameField Value
| Type | Description |
|---|---|
| String |
Properties
AgentGameObject
The reference of the root of the agent. This is used to disambiguate objects with the same tag as the agent. Defaults to current GameObject.
Declaration
public GameObject AgentGameObject { get; set; }Property Value
| Type | Description |
|---|---|
| GameObject |
CellScale
The scale of each grid cell. Note that changing this after the sensor is created has no effect.
Declaration
public Vector3 CellScale { get; set; }Property Value
| Type | Description |
|---|---|
| Vector3 |
ColliderMask
The layer mask.
Declaration
public LayerMask ColliderMask { get; set; }Property Value
| Type | Description |
|---|---|
| LayerMask |
CompressionType
The compression type to use for the sensor.
Declaration
public SensorCompressionType CompressionType { get; set; }Property Value
| Type | Description |
|---|---|
| SensorCompressionType |
DebugColors
Array of Colors used for the grid gizmos.
Declaration
public Color[] DebugColors { get; set; }Property Value
| Type | Description |
|---|---|
| Color[] |
DetectableTags
List of tags that are detected. Note that changing this after the sensor is created has no effect.
Declaration
public string[] DetectableTags { get; set; }Property Value
| Type | Description |
|---|---|
| String[] |
GizmoYOffset
The height of the gizmos grid.
Declaration
public float GizmoYOffset { get; set; }Property Value
| Type | Description |
|---|---|
| Single |
GridSize
The number of grid on each side. Note that changing this after the sensor is created has no effect.
Declaration
public Vector3Int GridSize { get; set; }Property Value
| Type | Description |
|---|---|
| Vector3Int |
InitialColliderBufferSize
The Estimated Max Number of Colliders to expect per cell. This number is used to pre-allocate an array of Colliders in order to take advantage of the OverlapBoxNonAlloc Physics API. If the number of colliders found is >= InitialColliderBufferSize the array will be resized to double its current size. The hard coded absolute size is 500. Note that changing this after the sensor is created has no effect.
Declaration
public int InitialColliderBufferSize { get; set; }Property Value
| Type | Description |
|---|---|
| Int32 |
MaxColliderBufferSize
The absolute max size of the Collider buffer used in the non-allocating Physics calls. In other words the Collider buffer will never grow beyond this number even if there are more Colliders in the Grid Cell. Note that changing this after the sensor is created has no effect.
Declaration
public int MaxColliderBufferSize { get; set; }Property Value
| Type | Description |
|---|---|
| Int32 |
ObservationStacks
Whether to stack previous observations. Using 1 means no previous observations. Note that changing this after the sensor is created has no effect.
Declaration
public int ObservationStacks { get; set; }Property Value
| Type | Description |
|---|---|
| Int32 |
RotateWithAgent
Rotate the grid based on the direction the agent is facing.
Declaration
public bool RotateWithAgent { get; set; }Property Value
| Type | Description |
|---|---|
| Boolean |
SensorName
Name of the generated
Declaration
public string SensorName { get; set; }Property Value
| Type | Description |
|---|---|
| String |
ShowGizmos
Whether to show gizmos or not.
Declaration
public bool ShowGizmos { get; set; }Property Value
| Type | Description |
|---|---|
| Boolean |
Methods
CreateSensors()
Create the ISensors. This is called by the Agent when it is initialized.
Declaration
public override ISensor[] CreateSensors()Returns
| Type | Description |
|---|---|
| ISensor[] | Created ISensor objects. |
Overrides
GetGridSensors()
Get an array of GridSensors to be added in this component. Override this method and return custom GridSensor implementations.
Declaration
protected virtual GridSensorBase[] GetGridSensors()Returns
| Type | Description |
|---|---|
| GridSensorBase[] | Array of grid sensors to be added to the component. |
