+# 废弃方法修复记录
+
+## 修复日期
+2024年
+
+## 修复的废弃方法
+
+### 1. Go 标准库 - `math/rand`
+
+#### 修复内容：
+- **废弃方法**: `rand.Seed(time.Now().UnixNano())`
+- **修复方案**: 完全移除该调用
+- **原因**: Go 1.20+ 中随机数生成器自动种子化，不再需要手动调用 `rand.Seed()`
+- **文件**: `main.go`
+
+#### 变更：
+```go
+// 修复前
+import (
+    "math/rand"
+    "time"
+)
+
+func main() {
+    rand.Seed(time.Now().UnixNano())
+    // ...
+}
+
+// 修复后
+func main() {
+    // 不再需要 rand.Seed() 调用
+    // ...
+}
+```
+
+### 2. Ebitengine v2.5+ - 图形绘制 API
+
+#### 修复内容：
+- **废弃方法**: `ebitenutil.DrawRect()` 和 `ebitenutil.DrawLine()`
+- **新方法**: `vector.DrawFilledRect()` 和 `vector.StrokeLine()`
+- **原因**: Ebitengine v2.5 后推荐使用性能更好的 vector 包
+- **文件**: `internal/game/game.go`
+
+#### 主要变更：
+
+**矩形绘制：**
+```go
+// 修复前
+ebitenutil.DrawRect(screen, x, y, width, height, color)
+
+// 修复后
+vector.DrawFilledRect(screen, float32(x), float32(y), float32(width), float32(height), color, false)
+```
+
+**线条绘制：**
+```go
+// 修复前
+ebitenutil.DrawLine(screen, x1, y1, x2, y2, color)
+
+// 修复后  
+vector.StrokeLine(screen, float32(x1), float32(y1), float32(x2), float32(y2), 1, color, false)
+```
+
+#### 修复位置：
+1. 游戏背景绘制
+2. 预览区域背景
+3. 网格线绘制
+4. 方块绘制 (`drawBlock` 方法)
+5. 幽灵方块绘制
+6. 下一个方块预览
+
+### 3. 导入包更新
+
+添加了新的导入：
+```go
+import (
+    // ... 其他导入
+    "github.com/hajimehoshi/ebiten/v2/vector"
+)
+```
+
+## 性能优势
+
+### Vector API 优势：
+1. **更好的性能**: vector 包使用 GPU 加速绘制
+2. **更准确的渲染**: 减少了像素对齐问题
+3. **未来兼容性**: 与 Ebitengine 的发展方向一致
+
+### 随机数优化：
+1. **自动优化**: Go 1.20+ 的随机数生成器自动优化
+2. **更好的随机性**: 不需要手动种子化
+3. **代码简化**: 减少了样板代码
+
+## 验证结果
+
+- ✅ 编译成功
+- ✅ Lint 检查通过 (无废弃警告)
+- ✅ 功能测试正常
+- ✅ 多平台构建正常
+
+## 影响评估
+
+- **兼容性**: 完全向前兼容
+- **功能**: 无功能变化，纯技术升级
+- **性能**: 理论上性能有所提升
+- **维护性**: 符合最新最佳实践
+
+## 建议
+
+1. 定期运行 `make check` 检查代码质量
+2. 关注 Ebitengine 官方更新，及时采用新 API
+3. 保持 Go 版本更新以享受最新优化
