注意
本記事で掲載されている動作の実装方法及びプログラムのソースコードは最適な方法ではない可能性があります。今後不具合等が判明した場合には修正及び改良をおこなう可能性があります。
また今後自分で同機能を実装する場合の参考にする可能性もあるためソースコードだけではなく説明しつつ記事を進めていきます。
Unityによる自作ゲーム開発進捗その２０になります！
今回は遊撃キャラクターを作成して戦闘レーンの変更指示を実装しました。
戦闘画面のUIはまだ作成していないので【1, 2, 3】【8, 9, 0】のキーボードボタンで指示を出せるようにしています。
既存のスクリプトを２つ新しいスクリプトを２つ更新します。
以下に動画でのコピー用にソースコードを掲載しています。

*/現在は【PlayerController】から入力をおこない【CharacterManager】経由で【遊撃部隊のキャラクター】へ指示が伝わるようにしています。

if (Input.GetKeyDown("0")) m_character_script.AttackerCommand(2, Number.Right); // タスク６【PlayerController】からの入力により【CharacterManager】の関数である【AttackerCommand】を呼び出しています。
public void AttackerCommand(int a_attacker, int a_position) {
switch (a_position) {
case Number.Left:
if (a_attacker == 1) {
m_attacker1_position = Number.Left;
m_knight_script.LineChange("Left", m_left_state); // タスク３
} else {
m_attacker2_position = Number.Left;
m_bishop_script.LineChange("Left", m_left_state); // タスク３
}
break;

if (a_attacker == 1) {
m_attacker1_position = Number.Center;
m_knight_script.LineChange("Center", m_center_state); // タスク３
} else {
m_attacker2_position = Number.Center;
m_bishop_script.LineChange("Center", m_center_state); // タスク３
}

} else {
m_attacker2_position = Number.Right;
m_bishop_script.LineChange("Right", m_right_state); // タスク３
}
break;
}
}【AttackerCommand】では引数１の数値により遊撃部隊１か２を指定するようにして引数２で守らせるレーンの数値を受け取り遊撃部隊に付いている関数【LineChange】を呼び出すようにしています。
public void LineChange(string a_line, int a_number) {
m_base_state = a_number;
for (int l_loop = 0; l_loop <= a_number; l_loop += 1) {
GameObject l_object = GameObject.Find(string.Format("{0}Base{1}", a_line, l_loop));
m_serch_object[l_loop] = l_object.transform.Find(string.Format("SetPositionA{0}", m_attacker));
}
m_navmesh_agent.SetDestination(m_serch_object[m_base_state].transform.position);
m_animator.SetBool("animation_move", true);
e_state = STATE.SET;
}【LineChange】関数では守るべき拠点が入っている配列内容を書き換えています。
書き換えた後に変更先の一番前線の拠点へ向かっていくようにしています。
今回作成した【Knight】と【Bishop】については現在各レーンを防衛している指揮官キャラクターと同様のプログラムに加えて初期化関数でレーン防衛キャラクターか遊撃キャラクターか指定可能なシステムにしています。
次回以降に他の指揮官キャラクターにも反映してキャラクターの入れ替えに対応する予定です。
