私が抱えている問題は、落としたアイテムに銃に弾薬を加えることです。FindObjectOfTypeがnullを返す
すべてのメソッドと変数でGunクラスを構築しました。 はライフルが、私は今、敵のx量はピックアップをドロップする「ピック」システムを追加してい完璧な問題なし
作品 銃クラスから派生ライフルクラスを内蔵します。
この
public class AddARAmmo : MonoBehaviour
{
private Rifle rifle;
private void Awake()
{
rifle = FindObjectOfType<Rifle>();
}
private void OnTriggerEnter(Collider other)
{
if (other.tag == string.Format("Player"))
{
rifle.AddAmmo(30);
Destroy(gameObject);
}
}
}
をピックアップする項目のスクリプトライフル銃のスクリプトは一種の長いですが、ここでは関係のものがガンの基本クラスからでは、パブリック抽象クラスです..... 。
ライフルクラスで次にpublic int bulletsInStock;
public void AddAmmo(int ammoToAdd)
{
bulletsInStock += ammoToAdd;
UpdateAmmo();// updates on screen Ammo
}
......
public override void Modifiers() // This is where the guns starts are stored
{
bulletSpeed = 2777f;
bulletsInStock = 200;
bulletsInMag = 30;
bulletPoolSize = 40;
desiredRPS = 15;
muzzleFlashPoolSize = 10;
}
私は設定していないオブジェクト参照を取得していますインスタンスに
ライフルスクリプトはゲーム階層のライフルにあるので、それを見つけるはずです。 誰かが間違っていると思っていますか？
のは、スクリプト名を言ってみましょう：ここ
