Syntax

public struct ActionSpec

Fields

BranchSizes

An array of branch sizes for our action space.

For an IActuator that uses a Discrete SpaceType, the number of branches is the Length of the Array and each index contains the branch size. The cumulative sum of the total number of discrete actions can be retrieved by the SumOfDiscreteBranchSizes property.

For an IActuator with a Continuous it will be null.

Declaration

public readonly int[] BranchSizes

Field Value

Type	Description
Int32[]

Properties

NumContinuousActions

The number of actions for a Continuous SpaceType.

Declaration

public int NumContinuousActions { get; }

Property Value

Type	Description
Int32

NumDiscreteActions

The number of branches for a Discrete SpaceType.

Declaration

public int NumDiscreteActions { get; }

Property Value

Type	Description
Int32

SumOfDiscreteBranchSizes

Get the total number of Discrete Actions that can be taken by calculating the Sum of all of the Discrete Action branch sizes.

Declaration

public int SumOfDiscreteBranchSizes { get; }

Property Value

Type	Description
Int32

Methods

MakeContinuous(Int32)

Creates a Continuous ActionSpec with the number of actions available.

Declaration

public static ActionSpec MakeContinuous(int numActions)

Parameters

Type	Name	Description
Int32	numActions	The number of actions available.

Returns

Type	Description
ActionSpec	An Continuous ActionSpec initialized with the number of actions available.

MakeDiscrete(Int32[])

Creates a Discrete ActionSpec with the array of branch sizes that represents the action space.

Declaration

public static ActionSpec MakeDiscrete(params int[] branchSizes)

Parameters

Type	Name	Description
Int32[]	branchSizes	The array of branch sizes for the discrete action space. Each index contains the number of actions available for that branch.

Returns

Type	Description
ActionSpec	An Discrete ActionSpec initialized with the array of branch sizes.
