私は個人的なプロジェクトに取り組んでいますが、まだXNAとC＃に非常に精通しています（VisualBasicとC++の経験があります）。このプロジェクトは、実際のゲームを開始する前に、コードとアルゴリズムをテストしているだけです。
私が抱えている問題は、Enterキーを押したときにマップ上に球をスポーンしようとしていますが、非常に基本的な衝突検出があるため、球を互いにまたはプレーヤーの上にスポーンさせたくありません。システム。
特に問題は、原点で部屋を見つけることができるはずなのに、部屋を見つけると奇妙な長方形が返されることです。また、球を別の球の上にスポーンすることもあります。プレーヤーを球体に移動すると、クラッシュが発生します。
ここに問題があるはずです-
if (currentKeyState.IsKeyDown(Keys.Enter) && newBallDelay == 0)
{
Npcs newBall = new Npcs();
//find room
Rectangle rect;
if (findRoom(newBall, ref rect))
{
newBall.postion = new Vector2(rect.X, rect.Y);
characters.Add(newBall); //adds to a list of Npcs which is drawn in a foreach loop
newBallDelay = 1; //prevents from adding too many spheres at once
}
}
これは
bool findRoom(Npcs newObject, ref Rectangle rectObject)
{
Rectangle player = new Rectangle((int)spritelocation.X, (int)spritelocation.Y, (int)sprite.Bounds.Width/4, (int)sprite.Bounds.Height/4);
Rectangle check;
for (int i = 0; i < characters.Count; i++)
{
check = new Rectangle((int)characters[i].postion.X, (int)characters[i].postion.Y, (int)characters[i].size.X, (int)characters[i].size.Y);
for (int j = 0; j < 50; j++)
{
rectObject = new Rectangle(i * (int)newObject.size.X * 2, j * (int)newObject.size.Y * 2, (int)newObject.size.X, (int)newObject.size.Y); //size.X and size.Y are the height and width of the object, this creates rectangular grid to check through.
if (!rectObject.Intersects(player) && !rectObject.Intersects(check))
return (true);
}
}
return (false);
}
関連性があるとは思えませんが、newballdelayについては、これを更新しています
if (newBallDelay > 0)
{
newBallDelay++;
if (newBallDelay == 50)
newBallDelay = 0;
}
ご覧いただきありがとうございます。繰り返しになりますが、私はこのサイトに不慣れであり、コーディングに不慣れであると考えるべきだと思います。そのため、ヒントやアドバイスをいただければ幸いです。
編集：内側のforループを修正しました。jではなくiをチェックしてインクリメントしていました。それでも同じ問題。
編集2：FindRoomアルゴリズムは、その場に何かがあるかどうかに関係なく、2つの位置のいずれかを返すようです。
編集3：わずかな問題が見つかりましたスプライトを適切に検出するには、スプライトの長方形の高さと幅を4で割る必要があります。
これが役立つ場合の私のコード全体です（それが乱雑で適切な規則に準拠していない場合は申し訳ありませんが、私はまだ学習中です）
