## Summary

| Summary       | Based on what we learned in Chapter 1, we will make an item eating world using character movement speed and jump control. |
| ------------- | ------------------------------------------------------------------------------------------------------------------------- |
| Difficulty    | Beginner                                                                                                                  |
| Time Required | 30 Minutes                                                                                                                |



**Project Goals**

- Handling of item acquisition using OnTrigger event
- Understand how to apply Text UI
- Create UI Controller to reflect item acquisition in Text UI
- Understand how to control the height of the ZEPETO character's jump
- Understand how to control the movement speed of ZEPETO characters
