## 总结

| 总结   | 基于我们在第一章中学到的内容，我们将使用角色移动速度和跳跃控制制作一个吃东西的世界。 |
| ---- | ------------------------------------------ |
| 难度   | 初学者                                        |
| 所需时间 | 30分钟                                       |



**项目目标**

- 使用 OnTrigger 事件处理物品获取
- 了解如何应用文本用户界面
- 创建用户界面控制器以在文本用户界面中反映物品获取
- 了解如何控制 ZEPETO 角色的跳跃高度
- 了解如何控制 ZEPETO 角色的移动速度
