大学生が有料スマホゲームを作った全てを公開するよ(3)ゲームの構造・パズルとアクションの仕組み(前編)
の続き。

今回は、使ったスクリプトコンポーネントを全て公開しておく。
前回の記事も参考にしながら見てくれると良いと思う。

細かく触れると多すぎるので、
今回は工夫した点を特記する程度になってしまい申し訳ない。

もし需要があれば、掘り下げた記事も書くかもしれない。
スクリプトは、クリックすると表示されるよ。

作ったスクリプト及びコンポーネント一覧

ステージオブジェクト

スクリプト

プレイヤー、ブロック、敵、アイテム、その他のステージオブジェクトが継承する親クラス
SetStats関数では、int配列でオブジェクトの初期化情報を取得する。

StageObject.cs
StageObject.cs
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class StageObject : MonoBehaviour
{
    public SOType sotype = SOType.Unknown;
    public string SOstate = "";
    protected GameObject GC;

    public void Start()
    {
        Init();
    }

    /// <summary>
    /// Sets the stats.
    /// </summary>
    /// <param name="stats">int配列ください</param>
    public virtual void SetStats(int[] stats)
    {

    }

    protected virtual void Init()
    {
        //GameControllerのGameObjectを取得
        GC = GameObject.FindGameObjectWithTag("GameController");
    }

    public virtual void OnShiftStart()
    {

    }

    public virtual void OnShiftEnd()
    {

    }

public virtual void Die(){
        Destroy (gameObject);
    }

    //ゲッターの意味...
    public SOType GetSOType(){
        return sotype;
    }
}

コンポーネント

ステージオブジェクトは以下のコンポーネントを持っている。

  • Transform
  • ParticleSystem
  • CircleCollider 2D
  • Rigidbody 2D

ただし、必要に応じて以下の場合もある。

  • CircleCollider2DをBoxCollider2Dで代用
  • Animatorコンポーネントを持つ

あまり重要ではないので、基本は同じだと考えてもらって良い。

プレイヤー

pertica_shift_low.gif

Character.cs親クラス
PlayerクラスとEnemyクラスはChracter.cs継承している。

基本的にはRigidbodyCircleColliderを使って物理挙動を制御している。

入れ替わり時の時を止める処理は、timescale0にすることで実現してる。
エフェクト関係はtimescaleの影響を受けないように、Unscaledの設定にしている。

Character.cs
Character.cs
using System.Collections;
using System.Collections.Generic;

using UnityEngine.SceneManagement;

    protected int HP;

    public bool isDead(){

ブロック

pertica_reflectionwall.gif

全てBlockクラスを継承しているが、今のところ処理はなくBlockクラスは意味がなくなってしまった。

SwitchWallに関しては見た目をパーティクルに頼っているため、SetActiveの切り替えは違和感があった。(一瞬でパーティクルが消えるため)
スイッチ壁の切り替えの時は、ParticleSystemをPlayしたりStopして対応している。

Enemyクラスを親クラスとしている。
元々、HPを設けるつもりだったが今は必要ないので名残で使ってしまっている。

壁にぶつかった時の反射に関しては、Rigidbodyを使っている。
Physics2Dの設定でVelocity Thresholdを0にしないと低速の跳ね返りが無視されてしまい、変な跳ね返り方をするので要注意。

カメラ

このゲーム(pertica)のカメラはかなり特殊だ。
まず1つのシーンにカメラが3つある。

  • ScreenCamera
  • MainCamera
  • StarCamera

ほとんどはMainCameraの映像を利用する。
2Dの為、MainCameraはProjectionをOrthographicに設定する。
でもそれだと背景の星立体感が無くなった。

そこで、背景専用StarCameraを用意しMainCameraの子オブジェクトにした。

また、perticaは画面のアスペクト比が変わるとゲームが成り立たない。
全ての端末でアスペクト比を揃える必要があった。

でもそれだとスマホの画面に余白が出来てしまう。
余白部分をタップしても反応させるためにScreenCameraを用意したんだ。

UI

UIは特にスクリプトを作っていない。
uGUIButtonOnClickをインスペクター上で設定するだけで済ませている。
大抵GameManagerの関数を呼び出す事が多い。

BGM・SE

BGM、SEstaticなクラスを作る事で簡単に音を流せるように工夫している。

BGMSourceScriptを持つゲームオブジェクトを作成。
BGM_Dataという名前のスクリプタブルオブジェクトを作る。

BGM_Dataにファイルkeyを設定する。
BGMPlayer.PlayBGM(key)で簡単に再生が可能。
SEも同様の手順で使える。

コメント

需要があるか謎だが、スクリプトを全文公開してみた。

結構冗長な書き方をしてたり、コメント文が少ない。
実はいくつかバグも見つかってる...。

読むのが大変だと思うけど、実際に動いているコードだから信用はして良い。

このコードでどんな事が出来るかは、ゲームを見た方が早いかもしれない。

このゲームperticaは以下のリンクからインストールできるよ。

さて、次回はゲームのデザインの話でも書こうかな。
