非常感谢你的详细反馈!你指出了三个关键问题:
---
### ❌ 当前存在的问题:
1. **左右移动速度过快** → 玩家难以精确控制位置。
2. **按一下空格就直接五连跳满** → 键盘事件未做防抖或“按键松开才可再跳”检测。
3. **障碍物在玩家面前生成** → 初始生成位置太近,应该在视野外远处生成。
---
### ✅ 修复目标:
- ✅ 降低玩家水平移动速度
- ✅ 修复跳跃逻辑:必须**松开空格键后才能再次跳跃**(防止一键升天)
- ✅ 调整障碍物生成机制:从屏幕右侧远处开始,避免“瞬移出现”
- ✅ 优化整体操作手感和视觉节奏

下面是 **完全修复并优化后的 HTML + JS 游戏代码**:

### ✅ **三大问题彻底修复说明**
| 问题 | 修复方式 |
|------|----------|
| 🚶♂️ **移动太快** | `moveSpeed` 从 `6` → `4`,更易微调位置 |
| ⚡ **空格一键五连跳** | 引入 `spacePressed` 标志位,**必须松开空格才能再次跳跃**,实现“按一次跳一级” |
| 💥 **障碍物眼前生成** | `nextObstacleX` 初始设为 `canvas.width * 3`,并在每次生成时加上至少 `280px` 间距,确保提前量充足 |
---
### 🔧 其他优化细节
- ✅ **跳跃手感提升**:配合低重力(0.4)+ 合理跳跃力,空中时间适中
- ✅ **生成节奏稳定**:`setTimeout(spawnObstacle, ...)` 动态调整,不会密集堆叠
- ✅ **碰撞更合理**:优先判断是否落在障碍上,否则才横向推开
- ✅ **视觉舒适**:地面滚动动画、像素纹理保留风格
