角色控制器生成
using UnityEngine;

public class PlayerController : MonoBehaviour
{
    [Header("Movement Settings")]
    public float moveSpeed = 5f;
    public float jumpForce = 7f;
    public float gravity = -9.81f;

        isGrounded = controller.isGrounded;
        if (isGrounded && velocity.y < 0)
        {
            velocity.y = -2f;
        }
        
        // 移动输入
        float horizontal = Input.GetAxis("Horizontal");
        float vertical = Input.GetAxis("Vertical");
        Vector3 move = transform.right * horizontal + transform.forward * vertical;
        controller.Move(move * moveSpeed * Time.deltaTime);
        
        // 跳跃处理
        if (Input.GetButtonDown("Jump") && isGrounded)
        {
            velocity.y = Mathf.Sqrt(jumpForce * -2f * gravity);
        }
        
        // 重力应用
        velocity.y += gravity * Time.deltaTime;

        currentState = newState;
        stateActions[currentState]?.Invoke();
    }
    
    private void HandleMenuState()
    {
        Time.timeScale = 0f;
        // 显示菜单UI
    }
    
    private void HandlePlayingState()
    {
        Time.timeScale = 1f;
        // 隐藏菜单UI
    }
    
    // 其他状态处理方法...

高级功能与最佳实践

跨文件上下文理解

aiXcoder-7B支持跨文件代码生成,能够理解项目中的相关文件:

from hf_mini.utils import input_wrapper

# 生成基于其他文件上下文的代码
context = input_wrapper(
    code_string="""// 基于PlayerStats.cs的上下文
public class EnemyAI : MonoBehaviour
{
    private PlayerStats playerStats;
    
    void Start()
    {
        playerStats = FindObjectOfType<PlayerStats>();
    }
    
    void Update()
    {
        // 根据玩家状态调整AI行为""",
    later_code="\n    }\n}",
    path="EnemyAI.cs"
)

性能优化配置

# 使用量化减少显存占用
from transformers import BitsAndBytesConfig

bnb_config = BitsAndBytesConfig(load_in_4bit=True)
model = AutoModelForCausalLM.from_pretrained(
    "aiXcoder/aixcoder-7b-base",
    quantization_config=bnb_config,
    device_map="auto",
    attn_implementation='flash_attention_2'
)

# 内存使用统计
print(f"模型内存占用: {model.get_memory_footprint() / 2**20:.2f} MB")
print(f"最大显存分配: {torch.cuda.max_memory_allocated() / 2**20:.2f} MB")

微调自定义游戏代码

训练游戏专用模型

# 使用自有游戏代码微调
accelerate launch finetune.py \
    --model_id "aiXcoder/aixcoder-7b-base" \
    --dataset_path "./my_game_code" \
    --dataset_text_field "content" \
    --max_seq_length 2048 \
    --max_steps 5000 \
    --learning_rate 2e-5 \
    --fim_rate 0.6 \
    --num_proc 4

微调数据准备

创建游戏代码训练数据集:

{
  "code_string": "using UnityEngine;\n\npublic class GameManager : MonoBehaviour\n{",
  "later_code": "\n    public void StartGame()\n    {\n        // 初始化游戏逻辑",
  "path": "GameManager.cs",
  "language": "csharp"
}

常见问题与解决方案

问题1:生成的代码不符合项目规范

解决方案

# 在提示中添加项目规范
prompt = """// 项目规范:使用PascalCase命名类,camelCase命名变量
// 使用XML注释文档
// 遵循Unity编码标准

public class """

问题2:生成长代码时结构不完整

解决方案

# 使用结构化FIM提示
structured_prompt = input_wrapper(
    code_string="if (playerHealth <= 0)",
    later_code="\n    }",
    path="PlayerController.cs"
)

问题3:多文件上下文理解不足

解决方案

# 提供相关文件信息
context = """
// 相关文件:InventorySystem.cs, ItemDatabase.cs
// 当前文件:PlayerEquipment.cs

public class PlayerEquipment : MonoBehaviour
{
    private InventorySystem inventory;
"""
