简介

AI游戏逻辑生成利用大模型辅助生成游戏中的核心代码，包括状态机、AI行为树、战斗系统和道具系统等，加速游戏开发流程。

AI生成Unity C#脚本

// AI生成的Unity敌人AI控制器
using UnityEngine;
using UnityEngine.AI;

public class EnemyAI : MonoBehaviour
{
    public enum State { Idle, Patrol, Chase, Attack, Dead }
    
    [Header("状态")]
    public State currentState = State.Idle;
    
    [Header("参数")]
    public float detectRange = 10f;
    public float attackRange = 2f;
    public float moveSpeed = 3.5f;
    public float attackCooldown = 1.5f;
    public int maxHealth = 100;
    
    private NavMeshAgent agent;
    private Transform player;
    private int currentHealth;
    private float lastAttackTime;
    private Vector3 patrolTarget;
    
    void Start()
    {
        agent = GetComponent<NavMeshAgent>();
        agent.speed = moveSpeed;
        player = GameObject.FindGameObjectWithTag("Player").transform;
        currentHealth = maxHealth;
        SetPatrolTarget();
    }
    
    void Update()
    {
        if (currentState == State.Dead) return;
        
        float distanceToPlayer = Vector3.Distance(transform.position, player.position);
        
        switch (currentState)
        {
            case State.Idle:
                if (distanceToPlayer < detectRange)
                    currentState = State.Chase;
                else if (Random.Range(0f, 1f) < 0.01f)
                    currentState = State.Patrol;
                break;
            
            case State.Patrol:
                agent.SetDestination(patrolTarget);
                if (distanceToPlayer < detectRange)
                    currentState = State.Chase;
                else if (Vector3.Distance(transform.position, patrolTarget) < 1f)
                    SetPatrolTarget();
                break;
            
            case State.Chase:
                agent.SetDestination(player.position);
                if (distanceToPlayer < attackRange)
                    currentState = State.Attack;
                else if (distanceToPlayer > detectRange * 1.5f)
                    currentState = State.Idle;
                break;
            
            case State.Attack:
                agent.SetDestination(transform.position);
                if (distanceToPlayer > attackRange)
                    currentState = State.Chase;
                else if (Time.time - lastAttackTime > attackCooldown)
                {
                    Attack();
                    lastAttackTime = Time.time;
                }
                break;
        }
    }
    
    void Attack()
    {
        player.GetComponent<PlayerHealth>().TakeDamage(10);
    }
    
    public void TakeDamage(int damage)
    {
        currentHealth -= damage;
        if (currentHealth <= 0)
        {
            currentState = State.Dead;
            agent.enabled = false;
            Destroy(gameObject, 3f);
        }
    }
    
    void SetPatrolTarget()
    {
        patrolTarget = transform.position + Random.insideUnitSphere * 10f;
        patrolTarget.y = transform.position.y;
    }
}

AI生成行为树

// AI生成的简单行为树节点
public abstract class BTNode
{
    public enum Status { Success, Failure, Running }
    public abstract Status Execute();
}

public class Sequence : BTNode
{
    private List<BTNode> children = new List<BTNode>();
    
    public Sequence(params BTNode[] nodes) { children.AddRange(nodes); }
    
    public override Status Execute()
    {
        foreach (var child in children)
        {
            var status = child.Execute();
            if (status != Status.Success) return status;
        }
        return Status.Success;
    }
}

public class Selector : BTNode
{
    private List<BTNode> children = new List<BTNode>();
    
    public Selector(params BTNode[] nodes) { children.AddRange(nodes); }
    
    public override Status Execute()
    {
        foreach (var child in children)
        {
            var status = child.Execute();
            if (status != Status.Failure) return status;
        }
        return Status.Failure;
    }
}

小结

AI游戏逻辑生成能快速产出状态机、行为树等核心系统代码。生成的代码需手动调优参数（检测范围、移动速度等）和添加动画事件。建议先用AI生成原型，再在实际场景中迭代优化。
