ミサイルを追加

前回、敵(タレット)を作成したので、攻撃のバリエーションを増やす為にもミサイルを追加します。

ミサイルスクリプトでは以下の処理をする。
・移動処理（目標に一定角速度以下で回転しながら巡行）
・衝突を検知したら削除★
・有効時間経過で失速し落下★
・ダメージ等必要な情報を渡したり渡されたり★

★の部分は以前作成した弾丸スクリプトと同じなので、
継承を使いたいと思います。
親クラスとしてShotクラス、
その子クラスにBulletクラス、Missileクラスといった感じに作成します。

以下のようになりました。

public class Shot : MonoBehaviour {
	public float speed = 100;
	public int effectiveTime = 30;
	public float damage = 100;
	protected int elapsedTime = 0;
	protected Vector3 movementSpeed;

	void Start () {
		Rigidbody rigidbody = GetComponent<Rigidbody>();
		movementSpeed = new Vector3 (0,0,speed);
		rigidbody.velocity = transform.rotation * movementSpeed;
		elapsedTime = effectiveTime;
	}

	void OnCollisionEnter(){
		Destroy (this.gameObject);
	}

	public void Create(float damage,float speed,int effectiveTime){
		this.speed = speed;
		this.damage = damage;
		this.effectiveTime = effectiveTime;
	}

	void Update () {
		elapsedTime--;

	}

	protected void OutRange(){
		if (elapsedTime <= 0) {
			Rigidbody rigidbody = GetComponent<Rigidbody>();
			rigidbody.drag = 0.2f;
			Vector3 tmpSpeed = rigidbody.velocity;
			tmpSpeed.y -= 0.8f; 
			rigidbody.velocity = tmpSpeed;
			transform.rotation = Quaternion.LookRotation (tmpSpeed);
			if (elapsedTime <= -300) {
				Destroy (this.gameObject);
			}
		}
	}
}

public class Shot : MonoBehaviour {

public float speed = 100;

public int effectiveTime = 30;

public float damage = 100;

protected int elapsedTime = 0;

protected Vector3 movementSpeed;

void Start () {

Rigidbody rigidbody = GetComponent<Rigidbody>();

movementSpeed = new Vector3 (0,0,speed);

rigidbody.velocity = transform.rotation * movementSpeed;

elapsedTime = effectiveTime;

}

void OnCollisionEnter(){

Destroy (this.gameObject);

}

public void Create(float damage,float speed,int effectiveTime){

this.speed = speed;

this.damage = damage;

this.effectiveTime = effectiveTime;

}

void Update () {

elapsedTime--;

}

protected void OutRange(){

if (elapsedTime <= 0) {

Rigidbody rigidbody = GetComponent<Rigidbody>();

rigidbody.drag = 0.2f;

Vector3 tmpSpeed = rigidbody.velocity;

tmpSpeed.y -= 0.8f;

rigidbody.velocity = tmpSpeed;

transform.rotation = Quaternion.LookRotation (tmpSpeed);

if (elapsedTime <= -300) {

Destroy (this.gameObject);

}

以下のようにミサイルタレットを作成できました。
