## 概要

| 概要    | 第1章で学んだことに基づいて、キャラクターの移動速度とジャンプ制御を使用してアイテムを食べる世界を作ります。 |
| ----- | ------------------------------------------------------ |
| 難易度   | 初心者                                                    |
| 必要な時間 | 30分                                                    |



**プロジェクトの目標**

- OnTriggerイベントを使用したアイテム取得の処理
- Text UIの適用方法を理解する
- アイテム取得をText UIに反映させるUIコントローラーを作成する
- ZEPETOキャラクターのジャンプの高さを制御する方法を理解する
- ZEPETOキャラクターの移動速度を制御する方法を理解する
