IadsCommsAgent.cs -> IADS Proxy for supporting mailbox message sending and recieving. Created a proxy that extends IAgent so that Mailbox can support IADS. Mailbox only supports Agents and adding a proxy makes IADS a part of an agent.

Code Review

This pull request adds the IadsCommsAgent class to handle mailbox communication as a proxy. The review feedback suggests correcting a typo in the class description and replacing Time.time with a deterministic fallback value for elapsed time.

Using Time.time as a fallback for SimManager.Instance.ElapsedTime can lead to non-deterministic behavior. In a simulation, Time.time represents real-time since the application started and does not account for simulation-specific logic such as pausing, time-scaling, or custom clock offsets managed by SimManager. If SimManager is expected to be present during simulation, falling back to Time.time might mask initialization issues or cause timing discrepancies.

public float ElapsedTime => SimManager.Instance != null ? SimManager.Instance.ElapsedTime : 0f;

📝 Walkthrough

Walkthrough

A new file Assets/Scripts/IADS/IadsCommsAgent.cs introduces the IadsCommsAgent class, a MonoBehaviour implementing the IAgent interface as a communications-only proxy. The class exposes configuration properties for a HierarchicalAgent, movement vectors, and agent components (Movement, Controller, Sensor, TargetModel). State accessors provide position, velocity, acceleration, elapsed time, and transform information. Several IAgent methods that involve movement capabilities or target-model lifecycle operations intentionally throw NotSupportedException with descriptive messages. A Terminate() method handles agent termination with event notification.

⚠️ Potential issue | 🟠 Major

Ensure HierarchicalAgent is never null.

Assets/Scripts/Hierarchical/HierarchicalAgent.cs:47-48 dereferences agent.HierarchicalAgent inside OnTerminated handlers. If this proxy terminates before HierarchicalAgent is initialized, this can throw at runtime.

+    _hierarchicalAgent ??= new HierarchicalAgent(this);
+  }

   public HierarchicalAgent HierarchicalAgent {
