Given a scenario where an farmer agent walks around a meadow that is randomly generated with a farmer, horse, pig, chicken and various obstacles like trees and boulders. does the following scripts look okay? If not what may i need to change? farmeragent.cs using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.AI; using Unity.MLAgents; using Unity.MLAgents.Actuators; using Unity.MLAgents.Sensors; public class FarmerAgent : Agent { public GameObject horse; public GameObject pig; public GameObject chicken; public GameObject foodPrefab; public Transform foodDropPoint; public NavMeshAgent navMeshAgent; private bool isHorseFed; private bool isPigFed; private bool isChickenFed; private List<GameObject> foodObjects = new List<GameObject>(); private void Start() { navMeshAgent = GetComponent<NavMeshAgent>(); } public override void OnEpisodeBegin() { isHorseFed = false; isPigFed = false; isChickenFed = false; // Reset animal hunger horse.GetComponent<AnimalAgent>().isFed = false; pig.GetComponent<AnimalAgent>().isFed = false; chicken.GetComponent<AnimalAgent>().isFed = false; // Destroy all food objects foreach (GameObject foodObject in foodObjects) { Destroy(foodObject); } // Spawn new food objects for (int i = 0; i < 3; i++) { Vector3 randomPosition = new Vector3(Random.Range(-5f, 5f), 0f, Random.Range(-5f, 5f)); GameObject foodObject = Instantiate(foodPrefab, randomPosition + foodDropPoint.position, Quaternion.identity); foodObjects.Add(foodObject); } // Move farmer to random position Vector3 farmerPosition = new Vector3(Random.Range(-4f, 4f), 0f, Random.Range(-4f, 4f)); navMeshAgent.Warp(farmerPosition); } public override void CollectObservations(VectorSensor sensor) { // Is each animal fed? sensor.AddObservation(isHorseFed); sensor.AddObservation(isPigFed); sensor.AddObservation(isChickenFed); } public override void OnActionReceived(ActionBuffers actions) { Vector3 position = transform.position; Vector3 forward = transform.forward; float moveSpeed = 0f; float turnSpeed = 0f; int action = actions.DiscreteActions[0]; switch (action) { case 0: // Move forward moveSpeed = 1f; break; case 1: // Move backward moveSpeed = -1f; break; case 2: // Turn left turnSpeed = -1f; break; case 3: // Turn right turnSpeed = 1f; break; case 4: // Drop apple for horse DropFood(horse, FoodType.Apple); break; case 5: // Drop truffle for pig DropFood(pig, FoodType.Truffle); break; case 6: // Drop corn for chicken DropFood(chicken, FoodType.Corn); break; default: break; } // Apply movement and rotation transform.Translate(moveSpeed * Time.deltaTime * transform.forward, Space.World); transform.Rotate(0f, turnSpeed * Time.deltaTime * 100f, 0f); // Update perception sensors horseSensor.UpdateSensor(); pigSensor.UpdateSensor(); chickenSensor.UpdateSensor(); } private void DropFood(GameObject animal, FoodType foodType) { if (animal == null) { return; } Vector3 dropPosition = animal.transform.position + Vector3.up; GameObject foodObject.
