Dependencies: IAgent, IPolicy

Simple synchronous stepper implementation.

A straightforward stepper that performs the full observation-inference-action loop synchronously on the calling thread. On each Step() call:

Collects observations from all agents
Performs batched inference using the policy
Applies the resulting actions to the agents

This stepper blocks during policy inference and is suitable for simple scenarios or policies with fast inference times.

Public Functions

Symbol	Details
`Init`	Initialize the stepper with the given agents and policy.
`Step`	Execute one step of the agent-policy loop.

Init

inline virtual bool Init(const TArray&lt;TScriptInterface&lt;IAgent&gt;&gt; &InAgents,
                         const TScriptInterface&lt;IPolicy&gt; &InPolicy) override

Initialize the stepper with the given agents and policy.

Parameters

InAgents – [in] The array of agents to manage
InPolicy – [in] The policy to use for inference

Returns:

true if initialization succeeded, false otherwise

#	Direction	Name	Type	Description
1	—	`InAgents`	`const TArray< TScriptInterface< IAgent > > &`	The array of agents to manage
2	—	`InPolicy`	`const TScriptInterface< IPolicy > &`	The policy to use for inference

Step

inline void Step()

Execute one step of the agent-policy loop.

Performs the full observation-inference-action cycle synchronously:

Collects observations from all agents
Calls the policy’s BatchedThink method
Applies the resulting actions to each agent

This method blocks during policy inference.
