AImitationPlayerController

A Blueprint-extendable PlayerController that implements the single-agent imitation interface.

This class provides a convenient base for creating human demonstration collection scenarios. It includes helper functions for Enhanced Input integration.

To use:Create a Blueprint subclass of this controller Set the InputMappingContext property to your IMC asset (action space is built automatically from it) Override DefineObservationSpace to define the observation space Override Reset and Step to implement environment behavior

void DefineObservationSpace(FInstancedStruct &OutObservationSpace)

Define the observation space for this environment.

Parameters

  • OutObservationSpace (FInstancedStruct)

DefineObservationSpaceTyped

inline void
DefineObservationSpaceTyped(TInstancedStruct<FSpace> &OutObservationSpace)

Type-safe wrapper for DefineObservationSpace.

Parameters

Reset

void Reset(FInitialAgentState &OutAgentState)

Reset the environment and return the agent’s initial state.

Parameters

  • OutAgentState (FInitialAgentState)

Step

void Step(FImitationAgentState &OutAgentState)

Execute one environment step and return the agent’s imitation state.

Parameters

  • OutAgentState (FImitationAgentState)

Attributes
