Learn how create 2D Idle Clicker Game in Unity Section6 学習メモ

Last updated at Posted at 2023-03-05

概要

Learn how create 2D Idle Clicker Game in Unity Section6の学習メモです。
動きを把握するため、クラス図を書いたり実際に動かした際の試行錯誤を記録に残しています

開発環境

IDE:Rider
Unity:2019.4.40
OS:Windows10

図

実装したい動き

aaaaaaaaaaa.gif

1.Upgrade用のUIを開く。
2.Upgradeボタンを押すとMinerがUpgradeされる。

クラス図

image.png

クラス名 説明
BaseUpgrade Upgradeクラス、今後実装予定のElevator Warehouseの継承元にもなります。
ShaftUpgrade 継承元はBaseUpgrade。オーバライドしている関数はExecuteUpgradeのみ
UpgradePanelInfo UpgradeUIを構成する画像類を束ねているクラス。ScriptableObjectを作成
UpgradeManager UpgradeUIを開閉する際に使われるクラス。
ShaftUI uGui関係のクラス。今回の場合だとUpgradeUIの表示、更新ボタン押した後の画面更新を担当

これで合ってるの？Observerパターンが2つあるから困惑してます。

赤枠のObserverパターン
Upgradeを実行する処理に使われている。
BaseUpgrade（Observale）で現在のレベルの内部処理が行われ、ShaftUI(Observer)でUI側に反映しています。

黄枠のObserverパターン
UpgradeUIを開く処理に使われている。
ボタンを押すと、ShaftUI（Observale）のメソッドが実行され、UpgradeManagerクラス(Observer)で内部処理を行う。

イベント処理(ShaftUI)と内部処理(Upgrade)を分離することが目的と考えられる。
イベント処理と内部処理の依存関係を逆転させるために使っている感じがある。

実装

UnityEditor上の設定

Upgradesボタン押す前

image.png

オブジェクト名 説明
UpgradeManager UpgradeManagerスクリプトがアタッチされている。
Shaft Shaft,ShaftUI,ShaftUpgradeスクリプトがアタッチされる。
Upgarde-Button UpgradeUIを開くボタン。ShaftUI.OpenUpgradeContainerメソッドがアタッチされている。

UPgradesボタン押した後

オブジェクト名 説明
Close-Button UIを閉じる。UpgradeManager.OpenCloseUpgradeContainerメソッドがアタッチされている。
Upgarde-Button Upgradeを実行するボタン。UpgradeManager.Upgradeがアタッチされている。

各処理の説明
1.ShaftUIクラスのOpenUpgradeContainer
デリデートを使ってOnUpgradeRequestを実行する。（引数も渡している。）
OnUpgradeRequestにはUpgradeManager.ShaftUpgradeRequestが登録されている。

2.UpgradeManageクラスのUpdateUpgradeInfo
デリケートから渡された変数selectedShaftとselectedUpgradeをprivate変数に渡している。

3.UpgradeManageクラスのUpdateUpgradeInfo
shaftMinerInfoからの情報（アイコン　アイコンのテキスト）を取得。

4.UpgradeManageクラスのUpdateShaftPanelValues
Shaft、ShaftUpgradeクラスの情報（パラメーターの数値など）を取得する。

5.BaseUpgradeクラスのGetNextBoostProgress
ProgressBarの現在値を算出する。

6.UpgradeManageクラスのOpenCloseUpgradeContainer
UpgradeUIをactiveにする。

Upgradeする

1.BaseUpgradeクラスのUpgradeCompleted
所持金の処理
2.BaseUpgradeクラスのUpgradeNextBoostLevel

3.ShaftUpgradeのExecuteUpgrade
Shaft特有のUpgrade処理を実装する。
具体的には採掘スピード、運搬量の改善。
Upgrade数が10の倍数となると従業員の追加、移動速度が改善される。

4.UpgradeManagerのUpdateShaftPanelValues
UIの数値更新

5.BaseUpgradeクラスのGetNextBoostProgress
プログレスバーのUIを更新

Upgradeする（１０回）

上のUpgrade処理と類似した処理。
1-3を10回繰り返した後、4,5を実行する

感想

クラス図が増えて処理を追うのが難しいですね。ElevatorやWareHouseの場合でも実際に手を動かして習熟する必要があると思います。(Section7, Section8)

UpgradeManagerクラスの責務にuGui要素が含まれているのが気になりましたね。
ShaftUpgradeUI的なクラス設けて分けた方が良いのではと思った。

C#の文法でネックになっている点はActionとコルーチンだと気づきました。
他のUnityの講座でもよく使われている事例が多いので使いこなせたほうがいいですね。
